halicon kent gable wanted to know more about knife steels i told him you and dale was the ones to talk two..your friend stephen...buy the way how have you been?
Chris, I thought I'd drop you a line to make sure you have no intentions of quitting. I know you and Don go into the more technical end of cutlery that leaves most of us way behind. Ya'll need to be a little more patient with us, we don't have the knowledge on the subject ya'll pocess. I hope to learn alot more from you in the future. Stay with us good buddy.
I'm still waiting for my new Higonokami from Japan. In the meantime, here are three other springless pocket knives. Unfortunately, I don't own an old penny knife.
Sheldon knife- Also called "Current," it was patented in 1966 for budding and grafting.
Pat Crawford- I think Pat designed this in the middle 1970's and had it made in Japan.
Boye- A small, dropped-edge folder made of high-quality cast SS and a nickel-silver case.
I thought your comments were excellent, but I got excited and bought one on ebay as soon as I posted your picture. I know, childish of me. When it comes I'll take a pic and see what you think of it.
Always interested in the comments of others, thanks.
I'd love to be able to have and use some of the tools that I've seen. I am, however, just a simple front porch whittler that tends to make do with what I have. I do, though, like a more convex edge for the rough "scraping" that I do to shape a pit.
I also need to ensure that whatever tool I use is ergonomically suitable for my hands. Had Carporal Tunnel surgery on both hands and am dealing with arthritis now. Lot of the tools that are out there have very small handles.
I do get some pleasure in sharpening with an Arkansas oil stone, something about the relaxation of going slow and easy to get the result wanted. Am interested in the European oil stone that you spoke of. Tell me more.
Chris .. I think we're talking about similar processes .. your's refined .. mine accidental !!!
work-harden
vb
(Engineering / Metallurgy) (tr) to increase the strength or hardness of (a metal) by a mechanical process, such as tension, compression, or torsion
work-hardeningn
risk of work-hardened tools
Work hardening can cause other problems as well. Tests conducted at Old Sturbridge Village in 1980 showed that the faces of anvils, normally tempered to around 55 on the Rockwell C scale, can work harden to as high as 72 on the Rockwell C scale after many years of hard service. This is a major cause of anvil failure. The face becomes so embrittled by repeated hammering that it eventually chips, spalls, cracks, or breaks away from the body.
Work embrittlement happens to forging hammers as well, and the wise smith retempers his hammers periodically to relive some of the stresses that have built up in them over time. ––Ray Larsen
I'm kinda sorta familiar with "work hardening". That is .. I've witnessed it's effects.
Let me do some more checking .. I'm guessing similar "reactions" occur .. perhaps @ a slower rate for wk hardening .. let me check some more & I'll get back to you.
That's interesting .. forging tools @ those low of temps .. is it a slow process ???

The Higonokami is so simple in design, as well as handsome. And I have a hunch it is good steel. Think I'll try to add one to my collection.
