Bladesmith’s Shop Tool Definitions

 

I have written a few shop tool definitions from a knifemakers perspective ©

FORGE
a refractory chamber heated to high temperature , then used to convert once usable metal into useless black scale or  artificial meteorites.
The forge consumes ridiculous volumes of evermore expensive propane from tanks the size of a small refrigerator that you have to lug down to the moving truck franchise store for refilling  and lift by yourself back into your truck because they are forbidden from helping you by corporate decree  in order to herniate that last good disc in your spine because you patronized their business.
also note that the forge has the potential to produce prodigious volumes of exhaust laden with toxic metal vapors and 20% carbon monoxide requiring continuous  cooperation of three huge noisy oscillating fans to dilute the risk of suffocation while ensuring either windchill or heat stroke  of the shop occupants depending on the season (except the resident mutant vermin, which are immune to extremes of temperature).
TONGS
large  and surprisingly heavy long metal plier-like tools used to retrieve red-hot artificial meteorites from the forge while pinching your fingers with a mechanical advantage five times greater than regular pliers
ANVIL
a solid steel tool which costs it’s weight in gold , used to back-up the action of a hammer in such a way that the red-hot metal being struck is launched unpredictably but usually towards your face at great velocity as the now very hot tongs slip and pinch your tissues while simultaneously burning you
TOE
a distal body appendage which mysteriously attracts falling objects (see hammer)
HYDRAULIC PRESS
a fearsome beast of a tool which can squeeze hot metal between it’s jaws to either flatten it or launch it at great speed off into the shop in order to ignite the one combustable item in the entire shop area (your new winter coat) all the while making terrifying squeaking and popping noises which can only occur in metal under 40 tons of pressure
WIRE FEED WELDER
A device which uses large amounts of high voltage to dim the lights in your workshop and tanks of expensive inert gasses in order to almost instantaneously convert a rolled spool of wire into horrible tangles of metal unsuitable for any birds nest while sending sparks out into the shop at surprising distances towards your socks, the inside of the cuff of the welding gloves you are wearing during the attempted operation and the other combustable items in the shop.
These actions are usually very quick and short in duration but the consequent actions of getting the hot slag off your skin, extinguishing your socks , immersing your new coat in the rusty water of the quenching barrel  and unwinding the wire tangle to get ready for the next attempted usage may take up the rest of the day which you had hoped would be productive
STICK WELDER
a less expensive , less complicated but equally power-demanding version of above  which does not create tangles of wire but   still creates the secondary effects as above with the added features of spitting molten metal slag everywhere around the item which was attempted to be welded. The slag is remarkably adherent to everything especially nicely polished or painted metal , and your skin , which it reaches by burning through your clothing like a high energy laser beam.
ETCHING SOLUTION
a special liquid laden with acid  or super-saturates of chemicals such as ferric chloride intended to eat away the outer layers of laminated steel objects such as labor intensive knives to demonstrate the pattern of the laminations and the hidden flaws in the steel which you have been working on for 3 days steady to then find that the item is unusable.
Etching solution will also instantly stain your skin brown until / unless it is replaced by new skin and reaches your skin by eating through anything in the way much like the molecular acid  blood of the of the creature  in the movie “Alien”.
QUENCHING BARREL
a container intended to hold clean water to cool hot steel , extinguish smoldering clothing and sustain mutant vermin which have invaded the shop and nested in your best coat which had been put safely away from the reach of welder slag into the cabinet that was supposed to be secure because of metal construction and the key, which has been lost in the bottom of the rusty water of the quenching barrel. Never drink from this barrel.
HAMMER
a volume of  randomly tempered steel in variable inferior configurations usually semi-attached to the end of a stick of marginal strength, conformation and durability  , which is intended to be used to force butter yellow hot metal covered with liquid glass flux from one distorted form into another while liberating a stimulating spray of the molten 20 Mule Team laundry borax mixed with termite powder and fluorospar intended to protect the metal surface from oxidation in the forge but which usually protects it from welding properly.
 Impact of the hammer transmits force to the  object being stuck, especially so if the object was not intended to be squashed. Generally speaking, the hammer may inadvertently become unleashed at maximal velocity when your glove which had been made hard  and greasy by satan’s appearance at the oil quenching ritual loses it’s grip, thereby launching into an observable primary trajectory and due to the handle, unpredictable secondary path to whatever is breakable and or painful within the workshop. (see Toe). Hammers are mystically attracted to breakable or soon to be painful unintended objects.
Occasionally (usually when new and used for the first time) the hammer head and handle will unexpectedly part ways in the most dangerous manner possible by separation at the hammer eye or breakage of the handle into sharp porcupine quills that stick into your face and mask while the hammer head ricochets about in search of breakable sensate objects (except vermin, which are invisible to hammers)
HIGH SPEED 2″x72″ BELT GRINDER
a device intended to grind hardened steel into pointy sharp knife-like objects all of which have the potential to be launched point first at high velocity into your liver, but usually used to convert swords into toothpicks and huge volumes of small particles of metal which escape the water filled bucket placed directly below  intended to catch the hot grinding sparks, so as to embed in your clothing , skin, and best coat back in the vermin nest cabinet.
Please note that the high speed belts used in the grinder can slice the end off your glove in a microsecond giving you an instant of clear view of your finger tip capillary arcade no longer contained by skin before more blood than you ever imagined could be in the end of your finger begins flowing so vigorously that it takes multiple wraps of black electrical tape to slow it down enough to apply crazy glue to stop the bleeding and affirm that the now bare nerve endings in the grinding zone are indeed alive now very angry at having been doused with crazyglue
SAFETY GLASSES
poly carbonate clear or specially tinted eyeware to protect your eyes from frying while looking into the hot forge or  being penetrated by flying objects when working in the shop , especially while using the belt grinder. Generally these tight fitting glasses make sweat drip directly into your eyes causing a burning feeling, then excessive tearing and interfere with your vision while reaching into the hot forge to retrieve hot artificial meteorites or grinding potential missiles and glove/finger tips on the belt grinder
MASK RESPIRATOR
a safety  device intended to be worn over your nose and mouth to protect you from inhaling dangerous particles or fumes from the shop environment. These are highly combustible if placed too close to the hot forge, if hit by a spark of hot metal at the anvil or belt grinder and have the added feature of displacing your safety glasses a bit so hot grit ejected from the belt grinder at high velocities can have chance for a trajectory to your eyes
Safety masks are surprisingly expensive and if you buy them via the internet are usually late in arriving , thereby causing you many unproductive days waiting for a new box of masks to arrive and finally forcing you to use old masks which have been taped over the burn holes and spontaneously fermented the volatiles accumulated from your breath into an aroma reminiscent of the bottom of the cat box after being used vigorously by your two cats during  that two week vacation to meet your crazy relatives in mississippi including your uncle who only has one tooth in his head.
GORILLA GLUE
a high performance expanding water proof adhesive activated by moisture intended for gluing handles onto the metal tooth picks you grind from swords which unintentionally spreads like a bad rumor to your clothing and hands despite nitrile gloves which you discover are solubilized by etching solution or gorilla glue.
Once on your skin, it turns black and will stay that way unless replaced by new skin or removed by uncomfortable , vigorous mechanical abrasion using your wife’s pedicure file which you clandestinely commandeer whenever she lets you enter back into the house to take a shower .
EPOXY GLUE
a high performance non-expanding two part adhesive which either never sets and remains permanently sticky or rapidly sets in an exothermic manner melting your mixing cup and permanently affixing the toothpick handles in misalignment while solubilizing your cheap nitrile gloves from china so as to gain access to your skin to accrue unwanted debris for later removal through vigorous mechanical abrasion.
CRAZY GLUE
a quick setting clear acrylic solution best used for hemostasis and testing residual sensory nerve function
POISON RAT BAIT
because your vigilant wife sees a rat walking on top of  the wall behind your pool which separates the civilized portion of your yard from Clampetville where your shop resides, then instructs the pest man (who ordinarily walks around your yard every two weeks spraying water and pretending to kill cockroaches) to kill the rat. He then places a mix of long acting tasteless anticoagulant poison and yummy (for vermin) suet enclosed in a   pet proof feeder box which the stupid filthy vermin eat, then die.
Then your dog secretively gorges upon dead rats and bleeds internally resulting in it’s  emergency admission to the canine ICU requiring multiple transfusions,  fractionated serum replacements  and your veterinarian finally being able to buy that new Porsche.
The poisoned rats which  were not eaten by your dog had taken agonal hiding in various corners of the shop and later make their location known by emitting “the dead rat smell” which is permanently absorbed by what remains of your once new coat. It is not a good summertime smell in your shop until 5 years afterwards and all the dumb rats have been removed from the diabolical vermin community.
ELECTRICAL TAPE
a multi purpose shop item used for holding knives and handles in misalignment while gluing for permanent misalignment, hemostasis, covering  holes in your fetid used masks, and thermally bonding onto whatever surface it is close to when hit by hot slag or molten flux.
MOBILE PHONE
an expensive device you keep in your pocket while you are working in the shop which your wife uses to notify you when lunch is ready or when toilets overflow . It never rings unless your hands are coated with glue and always falls out of your pocket into the quenching barrel when you are extinguishing your clothing thereby necessitating another visit to the cellphone store where the clerk calls you ” mister Sir”.
HOT PIPE
something you NEVER quench  more that once in your life, trust me on this one
SURFACE GRINDER
very heavy and difficult to move , a once upon a time precision machine which you bought via craig’s list when you once had money with the intention of making folding knives and beautiful distal tapered blades .  However it has been sitting for 3 years blocking your garage which is too full of stuff to park the car in there anyway, and gets moved to a new location in front of your workshop roll up door to block it from errant vehicles.
QUENCHING OIL
accumulated waste oil from the neighborhood mixed with ATF to achieve a lower viscosity intended for immersion tempering of hot steel to achieve destructive thermal shock fracturing of expensive complex steel items you worked on for many days.
Each quenching creates a huge cloud of smoke which always floats over to the hot forge where it ignites in an impressive fashion as if Satan were appearing while generating a small concussive sonic boom event which triggers the urban gunshot detection system stimulating the METRO police SWAT team to break through the door of your shop with weapons drawn in the first use of their medium armor urban assault vehicle ram accessory from DHS while wearing their new blue UN helmets.
They are mad because your surface grinder was in the way, causing their LAV to high-center and get stuck there.  You are  lucky they don’t shoot you but they “impound” all of your knives and give you a ticket for having an unlicensed commercial manufacturing facility in your yard while instructing that you have 30 days to tear down your shop because it does not meet the new building codes.
In addition , because of the quenching oil, you must pay an up front cash-only large arbitrary fee to have the site remediated by the EPA or they will confiscate your house. In their onslaught, they determine that your quenching tank is an unauthorized pond which has threatened the health of the shop vermin, which they declare a new endangered species.  The only reason you are released from handcuffs is that your wife hears the noise , goes past the pool wall  out to the shop and recognizes the lieutenant as the husband of her tennis partner who she calls to intervene by texting instructions to her ken doll to let you go.
There are more but I just got a call that I need to go plunge the toilet

Klingon Kleaver Warranty Repair

Image

IMG_0795 IMG_3515 IMG_3516 IMG_3518 IMG_3521I Recently  I had a new experience with the return of a knife for repair.

Not just a knife but a Klingon Kleaver complete with Electo-Etched Klingon Writing.

The tang had separated from the blade body but was still tightly installed in the handle.

The Klingon  field repair cutting tools technician has thermally fused the blade onto another tang while carefully protecting the blade temper through application of heat sink material and salvaged the “Cook or Fight” etching intact. see    KLI.Org
 
Thereafter, the blade was shortened by mechanical abrasion belt grinder approximately the dorsal skin thickness of a DenIb Qatlh  (Denebian Slime devil) and a new ricasso was established . The thermal fusion repair was not fully ground and was left as what it represents , a prideful scar for a tool well used.  Although now shortened, the blade retains good balance for kitchen craft and battle,with sufficient size of edge to dispatch jaghla’
A new brass ferrule has been machined, polished and fitted along with a new pressure impregnated stabilized olive wood handle of proprietary contour/configuration which has been attached using a binary catalyzed polymer.
The saya has been sanded smooth and new penetrating tung oil finish applied to enhance it’s appearance and serviceability.
The blade has been diamond honed after a careful flatside  polish to revive the cutting edge to renewed razor sharpness which was demonstrated on cellulose sheet.
The blade should be fully serviceable in one earth rotational period and is awaiting transport back to the owner.

 

Regarding Bob Kramer

This post by SamWise is referencing  Knifemaker artisan Robert Kramer. Why is that?

Well, I have been working away in my little personal sphere for the last 20 years or so and independently decided upon a pattern for inlay because I liked the symmetry.

For at least the last 15 years or so I have incorporated the three rods or three tubes inside another  tube as a decorative item in the handles of knives which I made.

I was recently introduced to the fact that Mr Kramer has had the similar appearing inlays in his knives and in fact, in his trade mark name.

So I went on the internet  and visited his site Kramerknives.com .  Sure enough, there was the triple rod inside a circle design complementing some very nice knives. His website indicates that he had started making knives in 1994 and had immersed himself in study so as to pass the ABS Master bladesmith testing. I have never met HIm , nor seen his knives in the first person.

Although I have been using this design for many years I had never registered it as a trademark.

So, for the record from this time forward I will unilaterally abandon the 3 circles/rods  inside  One circle design and begin using a different inlay which I believe is unique , although I have not done a search of marks and trademarks to know for sure.  The expense of doing a search is not something I want to sustain at this time.

So I now introduce my new inlay which looks like a Sun or a gear inside a circle. It looks very nice to me and as far as I know is unique to me.  If anyone comes forth with the same design I would be surprised , however, I have been surprised before.

Radius Knives

About Radius Knives

Knife making is an  unusual passion. Mine started back when I was a child and found an old case pocket folder by the train track. It had been sharpened vigorously and was missing it’s scales. I was given a scrap of walnut wood that I carefully planed to thickness and fitted to the existing pins. I even inlayed the name badge. To this day I have that knife in my desk pencil drawer.

Some 19 or 20 years ago I had decided to learn blacksmithing in order to make an ornamental fireplace poker. I searched for books and ended up with “Edge of the Anvil ” by Jack Andrews and Alexander Weyger’s nice books ( Modern Blacksmith and The Making of Tools ) which taught how to make a forge, use the anvil and draw temper.

I made a truck drum forge and salvaged an old kirby vacuum for a blower. In no time at all I was burning up steel and coal.

Early efforts looked more meteoric than useful metal craft but I persisted even after catching the dog on fire with flux spatter. ( The dog was perfectly fine, only a little singed on her dorsal fur).

I had learned how to make little ram’s heads, crocodile heads, snake heads and some other stylized forms on pulls and knobs.

Then I needed a hatchet , so I made 100 of them from OCS (old chevy springs). After that I made some knives from old files and knifemaking soon took over smithing.

I found the excellent books on pattern steel by Jim Hrisoulas invaluable. I had the good fortune to meet him at a SOF show and We have been friends ever since. His review of my work and suggestions for improving my skills has been a blessing.

Over time I have become reasonably adept at hand laminating carbon steels to make standard patterns in steel reliably. I am about to transition to power forging soon as my budget permits. I have been lucky to get power hammer instruction by jim Hrisoulas and the genius for stainless pattern steels,  Devin Thomas.

The quality of my cutlery has continually improved with each series of forms that I have completed. Back when I was throwing  pots in college I would make 100 of a form to gain skills and eventually  became  very adept at high fire stoneware . Applying the same diligence to blade smithing has guided my growth as a knifemaker exploring fixed blades.

Recently I have been making kitchen knives especially large Chinese pattern variations and gyuto forms. Increasing demand for these knives from friends and their referrals has resulted in this website. I have decided to offer several standard patterns and wildcard efforts here.

Recent inspiration resulted in a  new shotgun accessory which is process for patent. I will offer that device for sale here as well.

Knifemaking as Art and Craft

Making pattern steel is enjoyable at many levels. Planning for a pattern and selection of steel is the first phase. Consideration of the manual technique for the desired final pattern determines the sequence of needed steps .

Occasionally , I will have a knife in mind before I make the steel, but usually I make the steel without any predetermined final form.

Manual methods limit the productivity one can reasonably expect. Hammering by hand on an anvil is no competition with a hydraulic press or a big power hammer although the steps are the same. Access to a hot rolling mill and a blanchard grinder magnify ones effort significantly.

I was elated to try Devin’s 150kg ram powerhammer under his instruction. Now I need to figure out how to get one myself!

So as with art , a craft can mature through practice and the guidance of journeymen given to the apprentice.

 

Methods and Materials

Heat is a vital ingredient for bladesmithing and pattern steel making. Mechanical force is applied to hot steel to weld layers together and move the steel to the desired conformation. Having worked with clay I think about the steel  in a similar fashion , the heat makes the steel more ductile for mechanical forming.  Hammering hot steel on an anvil is the basic process.

Grinding is an important method beyond filing and scraping. I use an assortment of power grinders and have a well used Bader II 2 X 72″ belt grinder . Grinding technique is another practiced skill . Having a good grinder, good fresh belts  and experience improves outcome.

Initially , I had been interested in more of a primitive approach to metal smithing without measurements. Lately I have been convinced By Devin Thomas that measurement is a good thing, so I even bought some calipers! Even I can learn.

Heat treating is another aspect of bladesmithing that can be as complicated and elaborate as one can imagine. Consideration of the kind of steel is important if one wants to have a reliably fabricated product instead of a fractured paperweight.  I think every knifemaker has heard that unwanted “PING” after quenching that tells you “OOPS”.

Usually I direct oil quench but have used quench plate technique for thin forms like cleavers or gyutos.  Differential hardening is another sub-craft that can result in remarkable Hamon lines in the finished blades.  Japanese blade tradition has well developed clay-hardening practices using secret clay mixtures which are passed from master to apprentice. I have dabbled in differential heat treating.

Steels

The discovery of iron and it’s carbonized form (steel) are the lineage to modern bladesmithing. As more scientific understanding of metals has come about there has been a proliferation of specialty steels including stainless steels, tool steels and powder metal composites.

Usually I work with simple steels like L-6 or 1095 and limited stainless steels like  AEB-L.  If I can build my experience with a few predictable steels later I will have a stronger foundation to explore more exotic metals. Eventually I would like to transition to power methods and become proficient at making high performance pattern stainless steel.  ( one needs to have goals!)
