Joe, not that it lessens your point any, but I would suggest avoiding such statements as "I see that they collectively have over 100 years experience in the shop".

To the uninitiated it may sound impressive, but businesses often try to use that type of statement as a lure, and it could mean they have 100 people with 1 year of experience, 1 person with 50 years of experience and 100 minions, or 5 guys with 20 years of experience, and they would all result in *VERY* different products.

I know that's not the case with A&A, but we should always be mindful of what we pass on to thems that follow these threads behind us.... Happy

As far as what a quality blade *should* be able to do or not do, and the potential of the medium of Steel, I just wanted to share with everyone the requirements for the Journeyman status in the American Bladesmith Society, as it serves as a benchmark by which expert knifemakers judge their peers. The only difference between the "Journeyman" and "Master" status, is that the Master's test requires the same feats of a Pattern welded blade.

Excerpted from http://www.americanbladesmith.com/ABS_JSTest.htm

Below are the requirements of the piece itself, and note that *NO* stropping or honing is allowed between the test phases:

The applicant must have personally forged and performed all work on the test blade, with no other person physically assisting in its construction or heat-treating.

Only forged blades may be tested. Applicants for Journeyman Smith must test with a carbon steel knife. Damascus or laminated blades are not allowed as test blades for those seeking Journeyman Smith status.

Once the test begins, no work, not even light stropping, may be done to the test blade.

TEST KNIFE SPECIFICATIONS:
- Overall Length of Knife: Maximum fifteen (15) inches.
- Blade Width: Maximum two (2) inches.
- Blade Length: Maximum ten (10) inches from point to the beginning of either the guard, bolster, or handle of the - blade.
- Handle Configuration: Any handle configuration is acceptable with or without guard, bolsters, ferrule, etc.
- Handle material is irrelevant and solely the choice of the applicant.
- Blade Material: The Journeyman Smith may test with any forged steel of his or her choice except Damascus.

The test must be conducted in the following sequence:

NOTE: ALL TESTS MUST BE PERFORMED BY THE APPLICANT, EXCEPT AS SPECIFICALLY PROVIDED FOR IN THE ROPE CUTTING. THE MASTER SMITH IS TO SUPERVISE AND SERVE AS THE OFFICIAL ABS WITNESS.

1. ROPE CUTTING: THE PURPOSE OF THIS TEST IS TO TEST THE EDGE GEOMETRY AND SHARPNESS.
Applicant is responsible for supplying the test rope and ensuring that it is a minimum of one (1) inch in diameter. If the applicant brings a larger rope, the applicant will be judged using the same criteria as though the rope was one-inch (1) in diameter. The rope is to be hung in a safe manner, so that the end of the rope to be cut hangs loose without touching the floor or any other object. As a safety precaution, the rope is not to be hand held by another person during the rope-cutting test. The hanging end of the rope is to be marked with tape or a marker to clearly indicate the area that is to be cut. The cut must be approximately six (6) inches from the end of the free hanging rope. A minimum of one (1) cut must be made. The applicant is to aim at the mark with a two (2) inch margin of high or low being acceptable. The applicant must sever the rope in two with one stroke. If the applicant fails on the first attempt, the Master Smith will allow two more attempts. However, if the Master Smith believes that the failure to sever the rope is due to the lack of skill or strength of the applicant, the Master Smith may attempt the rope cutting with the test knife. This is a test of the applicant’s ability to make a knife, not to cut with it. If neither the applicant nor the Master Smith successfully cuts the rope, the applicant fails.

2. WOOD CHOPPING: THE PURPOSE OF THIS TEST IS TO DEMONSTRATE EDGE TOUGHNESS.
The chopping test is to be conducted with 2x4 construction grade wood stud. The 2x4 may be either hand held or clamped into a vise or other safe devise. A chopping motion (no whittling) is to be used. The 2x4 must be chopped completely through a minimum of two (2) times. The applicant may choose the area of the 2x4 through which to chop. Following the chopping test, the Master Smith will inspect the edge to determine if there is any noticeable damage to the blade. Any nicks, chips, flat spots, rolled edges, or other deformations of the blade will result in failing the test.

3. SHAVING HAIR: THE PURPOSE OF THIS TEST IS TO DEMONSTRATE EDGE RETENTION.
After the Master Smith approves the quality of the edge, the blade will be returned to the applicant. The applicant must then shave hair using the section of the blade that was most frequently used in the cutting and chopping portions of the test. Enough hair must be shaved to demonstrate that the edge remains keen and shaving sharp.

4. BENDING: THE PURPOSE OF THIS TEST IS TO SHOW THAT THE APPLICANT IS ABLE TO HEAT TREAT A KNIFE WITH A SOFT BACK AND A HARD EDGE.
The bending of the blade is the final test. Safety gear should be worn. At the discretion of the applicant or the Master Smith, the edge may be dulled prior to bending. The Master Smith will mark a line across the width of the blade approximately 1/3 distance from the tip of the blade. The blade will then be inserted into a vise, tip first, such that the blade is placed into the vise up to the mark on the blade. If the vise jaws are rough, smooth metal inserts shall be located on each side of the clamped portion of the blade to protect the blade, when bending the test knife. The blade shall be bent by force applied to the handle. A leverage device, such as a pipe may be used as long as it does not pose a safety risk. The use of such a device is at the sole risk of the applicant and at the discretion of the supervising Master Smith. The applicant will then bend the blade ninety (90) degrees. The supervising Master Smith will signal the applicant when the ninety (90) degree angle has been reached. The blade is allowed to crack at the edge on bending but not beyond approximately two thirds (2/3rds) the width of the blade. However, if any part of the blade chips or any part of the blade or tang breaks off, the applicant fails. Because of the many variables in the size, geometry, and temper line of the blade, the Master Smith using his/her judgment, shall determine if the extent or location of the fracture line is acceptable. The decision of the Master Smith is final.



So, in order, sever a free hanging 1" rope in one stroke, chop two 2x4's, and shave hair, all without "nicks, chips, flat spots, rolled edges, or other deformations", and no stropping or honing in between. I'd be surprised if the Classic swords we all admire even required a re-polish, merely a simple wipedown and rehoned edge if engaged against "fleshy" targets for posterity testing.

With that in mind, surviving a cut at a pork shoulder to me doesn't sound too unrealistic an expectation. The dead bone comments have been all said, but I think the message was missed on Swordforum, and never made it back here. It's not 'dead' bone that matters, it's 'dry' bone. As long as you have a fairly fresh piece of meat and bone, where reasonable precautions have been made to not let it dry out, it's a fairly valid test, and is probably more forgiving than anything other than a "green" 2x4 ("green" meaning a moisture content higher than 6% or so).

Certainly a knife has different requirements than a sword, as well as many people aim for how to create "the" piece to get them their status, and may not adhere to the standards once they have achieved it, but the intent is that *every* well made blade should be able to undergo this process and survive (the bending test being to the "extreme").

So, given that we know how a quality blade *should* hold up, we can plug that into the end product, and ask how our family of makers test for that result. I think everyone here (Gus, Tinker, et. al) has done a fair job of describing their process, and as we all attest to, these guys *do* deliver quality goods. Do they neccesarily test at the level of scrutiny described above? No, but I think they handle a certain amount of it, and could probably pass 75% of their products through without breaking a sweat, as well as there is a large audience of happy customers backing them up.

Should some new guy roll into town, think back to the ABS requirements, and be sure to ask the maker how he tests his finished products, and see if the objectives of a quality blade are looked at and adhered to, and how well it may stack up against the ABS guidelines.

Angus, Tinker, Craig, Peter, I'm saving my pennies.... Happy

Sincerely,
Matthew

I like looking at the site, and once I started digging around I found new stuff!

New to me anyway. Big Grin

Matthew,

I know but the point I was trying to make is that it can be relevant, if presented in proper context, for them.

I would have to say we are definitely in the heroic effort category. Though some days it feels more like the French Foreign Legion kind of heroic than the Henry the Vth type Eek!

In our process I would say the largest group of items that move through our assembly process on average is about 3 or 4. It just seems to give us the best result. Often individual swords are done start to finish due to scheduling and sometimes they are just bastards to get together right. We have a sneaky suspicion that they do have personalities.

Interesting points on the maturity level of companies. It is one of those things that one does not spend much time considering on a daily basis but it is crucial to long term success. Though I often think success in the sword business is equivalent to survival.

Craig,

I know you guys put in heroic effort with results that match. The "maturity" is for the process, not the company exactly - you can have very mature companies that have always relied on finding and retaining talented people whom they expect a lot of. Not sure this can be applied very well to sword companies of the sort we are talking about - not even sure it applies well to all software companies. The main questions are valid though - if quality control is maintained mostly through personal vigilance on the part of a few individuals, things will slip through that are substandard if those individuals relax that vigilance. And that has to occur sometimes - even if heroic, you guys are only human. It is not a knock against anyone, and returning such a product, or questioning one should not be considered an insult to the company, on either side. I know that all of "you guys" - Albion, Atrim, A&A are always willing to make things right if it should happened - and I think the large majority of of this community is quite comfortable with that.
