The true history of S30V development

By way of introduction my name is Dick Barber and worked as a metallurgist for 25 years with Crucible prior to leaving for my current position.
While at Crucible I was involved with directing our alloy development as chairmen of the technical review committee. During that time I attended the Oregon knife collectors meeting in Eugene where I met Chris Reeve who at that time was using BG 42. I asked Chris why he was not using our materials and he told me that if we made something better he would buy it. This conversation was the beginning of a project that I sheparded through our alloy development process to make a better knife steel. During that time Ed Severson and myself conducted inverviews with many other knife makers but Chris was the only one who had access to the early alloys which were made. In fact material for the first heat of S30V we made in the research lab was given to Chris to work with. From that material he made 4 knives, one was given to me, one to Ed Severson, Chris kept one and Scott Cook who ground the blades kept the fourth. Those knives were tested and compared to other materials and several suggestions were made for improvement in the alloy. From that point a second set of materials were melted and tested in the lab. From that came the origional CPM S30V as well as the later CPM S35VN. As a reward for his interest and feedback on the product Chris was the first maker who had access to commercial quantities of the alloy. Some have said in many posts that Chris had no involvement in the development process. I can say that if you were not there then you should not comment on what did or did not happen. I can say as one who was there that were it not for Chris and his persistance in pushing me there would not have been a CPM S30V or the alloys that followed.
 
Welcome to the forums sir, good to hear of steel history first hand such as this.

Welcome, and thanks for your insightful post:thumbup:

My favorite Sebenza steel is BG 42, but I also like S30V, and S35VN.

Thanks for the story. It certainly clears up what seems to have been .... differing views of the events.
 
When CPM S30V was concieved we were looking for an improved basket of properties. There are materials that can get harder, some are tougher, some will hold an edge longer and many are much easer to cut grind and heat treat. What we tried to do with this project was to look for an alloy that would workable for the knife makers and give the best combination of toughness edge retention and corrosion resistance. BG-42 is probably a little easier to work with but will not resist edge wear as well since it has fewer and softer carbides.
 
Thanks for the factual commentary Dick, and welcome to the forum. If it is OK with you, I think that your descriptive should become part of the larger "CRK Timeline" sticky for everyone to reference as the years pass. This question will come up again in the future no doubt.

I've seen 'opinions' all over the net about Chris' involvement in S30V's development, so it's good to hear it from the proverbila 'horses mouth'.

Thanks for posting.
 
Thanks for sharing! I only have one CRK, but I have more S30V knives than any other steel, so I'm always happy to learn more about it.
 
Very interesting post. Thank you for bringing S30V to life. Great all-round steel.
 
s30v......Works great on Ohio whitetails....................Love it..............................carl
 
Thanks for S30V got many blades in it one of my favorites for being low maintenance. It holds and edge, is very corrosion resistant in my use.
