Pray pardon me milady Tatiana; I fear I could not help but overhear you

asking about knife steels as I loitered on this bridge. May I converse

with you about this?

 

I am afraid I did not catch what tools you have access to so I will

provide various options.

 

The old file, (and I mean "old" file, some modern files are playing

fast and loose with case-hardening and powder metallurgy!) is oft used

due to its carbon content, often being close to 1%!, ease of procurement

and the advantage of it being already tempered to a hard and brittle state.

This  is an advantage to people who have not access to a forge, kiln, torch

or other commonly used method of heat treating a blade. The file, already

being tempered too hard, is drawn to a tougher temper using a kitchen oven,

(depending on the file and how you plan to use/mis-use the knife and how you

like the blade, you would bake it at 400-550 F), then worked into the blade

being carefull to keep the temperature of the blade cooler than the drawing

temperature. The disadvantage is that the metal is still harder than

annealed stock and so it is more difficult to work.

 

If you were to step into a machine shop; you could ask for any of a number

of steels, based on what you wanted from your blade and what tools you

have access to.

Among them:

 

O-1, commonly available, fairly cheap, known and used by knifemakers for years.

This steel will rust and is heat treated by heating to its curie temperature

and quenching in oil.  In annealed state you can file/grind/abrade it to shape.

 

5160, commonly available as leaf spring stock--ask a springshop to buy scraps,

the pieces along the road oft contain hidden cracks and stresses! It should

be cheap. This material also will rust, and has a lower carbon content than O-1

so you will draw it to a different temperature after quenching it, (I prefer

an oil quench for 5160 as well)

 

440C, probably the most used steel by custom knifemakers. This is a stainless

steel that is very resistant to rust, takes a mirror polish and holds an edge.

(I can't talk about heat treat since I don't use this one much, a good

knifemaking book like _The Complete Bladesmith_ by Jim Hrisoulas should

cover it, (I never can remember Jim's sca name), or Machinery's handbook,

or ask at the machine shop). Probably more expensive than the others.

 

Steels not in ones best interest to try working by hand as a beginners project

include such things as D2, Stellite, VascoWear,... most being hard to work

and needing precise heat treating to get your money's worth from these alloys.

 

When I teach bladesmithing I usually try to use a simple straight carbon steel

like 1080, 1075, 1095; often salvaged from old farm equipment, spark tested,

and drawn to personal preference. Its only on their third knife that we start

talking about pattern welding!  (Morcant you lucked out!)

For knifemaking and other cutting questions may I make two

recommendations.

 

A.  Get an Atlanta Cutlery catalog.  Some good basic supplies and blank

blades.  Call 1-800-883-0300 and ask for a catalog.

 

B.  Check out the gun shows in your area.  I have rarely been to a gun

show where there was not someone selling brass fittings and bar stock for

hilts.  I got some decent exotic wood scales at a show this past weekend.

 

    Stock removal method is the easiest to master for a beginner.  You can

clamp a belt sander in a vice to approximate a table sander and get some

passable results.  To use tool steel, (such as old files) you either have

to spend a lot on abrasives or anneal the stuff to soften it first.

    A Glover pocket reference is good info.  It contains a lot on

engineering formulae and other neat info.  One thing is the relationship

to heated steel color and temperature for the type of steel.  A good quick

reference if you don't do forging regularly.

 

  Try junkyards for stock. One of the best shortswords I turned out (when

I had access to a forge many moons ago) started life as a leaf spring from

an old Packard.

 

Hope it helps,

I recently took a beginning knife-making class and now I'm all

pumped to make some sharp cutty things for my scribe's box.  The

instructor of the class advocated using old files to begin with.  

My question to any knowledgable person out there is:  If I walked

into my local metal shop to get suitable metal to make a small knife

(for eating, carving quills, gen.utility, etc.), what kind of bar

stock would I request?  

 

Many thanks for the assitance,

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I like ATS-34. Not quite as rust-resistant as 440c, but it seems to work

better for me. Easy to grind and hardens nicely. Will hold an edge better

than 440c, though it's not quite as strong. It won't darken and look

rustic (rusty?) with age, but for a general SCA knife you probably want

something stainless. Most knifemaker's supplys will have as much ATS as

any industrialized nation could ever want, but you probably have to buy a

foot of it at least.

Used files found at flea markets/yard sales will do what you need. Old

sayz or hacksaw blades work too. Chainsaw bars too.

If ou want good quality metal ask for 1095 or other 10xx number

metal.thats plain carbon steel. use 1045 - 1095

440 stainless is okay too as is D2 tool steel.

Try old Circular saw blades, until you get a good handle on the tricks.

They make good blades that hold up well, to everyday use.

Greetings

        There are several types of steel that will make excellent knives and

other cutting edge tools.  First you have to decide how you want to harden the

material oil, water , brine, or other exotic solutions. Water is the easiest

to get which would mean using a tool steel called W1 or W2.  If you decide to

use oil watch out for the flash back but O1 is an excellent knife steel.  Old

files and springs can be used but often there are stress cracks already in the

material when you get it used, many a blade has been lost to un seen cracks

that usually show up when you harden it.  New material is the best and that

way you know what you are getting.  Some suppliers will be able to give you a

copy of the hardening and tempering sequence for the particular tool steels

that they carry.  A word of caution these sheets are based on labratory

testing and as a blade smith your temperatures will be more by eye than

pyrometer.

        Best of Luck

Watch out for circular saw blades.  While the old ones were made with a good L6

steel mostly, many of the newer ones are made with high speed steels.  this

means that while you CAN make a knife out of them it is hard to forge and hard

to grind (not to ment

ion it is a pain in the rump to forge or cut a small pattern out of a circular

sheet of steel.)

      I would recommend going to your local wrecking yard and picking up a fairly

thin leaf spring.  If you have access to a table saw (NOT a skilsaw) put a

metal cutting blade (fiberberglass and emery thing) and cutting knife length

and width pieces out of it.

  If you have no saw then you will spend most of your time forging the profile

down.  I have had huge amounts of luck with this technique.  Besides you can

sometimes get the leaf springs gratis if they are broken. Good luck.

L.S.

 

I do not advocate the use of previously broken leaf springs for knife stock.

Failure mode for the spring seems to be the creation of multiple cracks

in the steel one of which propagates catastrophically, leaving the others

hidden in the metal to be discovered *after* you have already put a lot

of work into the blade.  Instead; go to a local spring maker and get their

"left-overs"  pieces left after they cut a length of stock for a spring.

If you talk nicely; they may give you 10 pounds or so of pieces free.

Otherwise I have always been able to buy at the going scrap rate.

 

After being "burned" a couple of times I have stopped using roadkill springs

and am much happier with the "good stuff"

Since this is a response to my own response I shall respond.  VERY GOOD POINT.

I have never made a large blade from a leaf spring because you never know

exactly what is in them but I have made many small ones and this may explain

the mysterious failure of a couple.  I shall now shop at the local spring maker like you.  Thanks

As far as Indian quality on edged weapons go..this varies, widely!  I have

run spectro's on all sorts of various and sundry items, both new and "old"

(200+ years) and the quality is subjective.

 

As it stands, professionally speaking, myself I wouldn't buy anything from

Museum replicas IF I was looking for a serious "social problem" solver,

(but then again, I am in the position of being able to make much better

items myself...Others are not as fortunate.).BUT  for the most part, as

far as what re-enactors and SCA types look for..Hey have at it. But

beware, as quality is variable from MRL... I have seen some decent stuff

come from them as well as a boat anchor or two..

 

MRL does however fill a niche, the one between the $40.00 cheapie sword

and the $750.00 and up custom....You do get what you pay for from a

reputable company, and this does apply to MRL.

 

If you are looking for something that looks decent and will not fall apart

in you hands, look at MRL...If you want a sword that is as good as you can

find...Well, you will have to go to a REPUTABLE blade maker and you should

be prepared to pay more, considerably more than the few hundred dollars

that MRL blades run.

 

I have seen some decent blades (especially those from the New Delhi Gun

House) that are wonderful, made from top quality materials and others,

still from India that were made from some "mystery metal" ...Unable to

harden, with very low (less than 30 points) carbon content...

 

All I can suggest is to look at the item, ask for a warranty and use you

best judgement....

In reply to your inquiry about blades..

 

After the first Crusade, the pattern welded blade pretty much disappeared due

to the time required to properly make them.. There was simply too much of a

demand for arms and the smiths tended to go towards the carburized iron...

While these made a servicable blade, the quality wasn't all that good...
