So I received this knife about 10 yrs ago from my brother inlaw (it's not a buck). and just last week I decided to do a little research on it. I was able to find out who made it and I got lucky and found contact info on him, so I gave him a call and what he told me was he had about 200 knife blanks cast out of stainless at a foundry, he then took them home and ground and polished them. Then he took 10 at a time to the ( buck factory in socal ) to have them heat treated for about 2 bucks apiece. This was in 1981 to 1984. I didn't know that this service was ever offered and I wonder if it still is. I just thought I would share this bit of trivia. Does anybody have any knowledge on this subject ?

My understanding is..... Paul Bos, semi retired, has an in house side business doing custom heat treating. Paul Farner now runs the heat treatment department.
You can see a listing of the custom services offered on the Buck factory website here... http://www.buckknives.com/about-knives/heat-treating/

Badhammer was a little quicker with the right info.....

Buck still offers heat treating using the Boss system. If you look in the heat treating section of their website it gives pricing and directions
 
I seem to learn something new every day. Thank you desotosky and badhammer, I knew someone would have the right answer.
 
Even in the 60's Paul Boss was doing heat treating and Buck started using him contractually for their heat treating work. Normally knife blanks are not cast, they are ground to shape. Then heat treated. DM
 
This is an unusual 1 piece dive knife made by gus marsh. Sea wolf knife co. U.s.a and it was made from cast stainless steel. Not only is the knife and manufacturing unusual but so is the whole story. There is some info on blade forum if any one is interested, I don't know how to add the link but if you check sea wolf knife co. U.s.a you will find it.
 
Custom knife maker David Boyle makes knives cast from dendritic 440C. The process is specialized and involved. And Mr. Boss heat treated this? DM

I guess S30V steel is cast into sheets first, due to it being a powdered steel...

Not cast. Hot Isostatic Pressed. Those are quite different processes.

Cast: The alloy is melted and poured into a mold.

HIP process: The powder goes into a form then it is heated and compressed, but not truly melted.

HIPped parts have significantly better properties than castings.
The dendritic casting process is not a standard casting process.
