Sterile Camillus BK-9 ??

Regarding one of the questions you asked on the original thread, It's been my experience that the stampings on the blade happen early in the manufacturing process. Usually shortly after the blank has been cut from the bare stock and while the steel is in an annealed state.

Thanks, sac troop. That's what I thought was the usual process, but I figured it was better to ask and be thought uninformed rather than spout an opinion and be proven a dumba$$.
 
I can't honestly say it would happen in every case. I think it would be somewhat dependent on the processing of the material. Certainly in the "old days" when forging was still at least part of the process it was the most sensible thing to do to apply the stamping when the metal was still very hot and malleable. As it is today with most products being of some kind of "stock removal" process, I suppose as long as the steal was in an annealed state they could stamp it whenever.
That being said I have a Camillus/Becker BK2 blade that was only ground to the primary bevel and it has it's factory stamping where you'd expect to see it.
 
Many knives since before the turn of the century have been fineblanked in dies. I have a "sterile" Schrade XT-2B knife, complete including blade coating and final edge. I also have factory blanks in every stage of production. Most, not all, have the tang stamps applied before heat and cryo treating. A few, particularly protos do not. I think Mr. Gibbs or another knowledgable former employee can tell us more about the process for tang marking and how knives might escape it in production.
 
Codger, great point about the fine blanking. I'm a little familiar with the process as it's been quite common in the automotive industry for a long time. Someone told me that it started in Europe around the 1920's. Certainly would be great way to produce large numbers of uniform blanks.
 
Of course you understood I meant the turn of this century? Schrade was well into conversion of many patterns when their balloon went up. I assume (but do not know) that their sister Camillus was likewise engaging in fineblanking. This allowed them to combine several process steps into one. And reduced the amount of work required to remove flash and rough edges from knife blanks. Or so it was explained to me by a former Schrade engineer.
 
As much as I hate to admit that I've entered a new century I was assuming you meant the turn of the last one.:)
I'm not really sure about the 1920's time frame. Only that I recalled hearing that.
