Carbon V definately came first. It was the brainchild of the Metal God, Dan Maragni, & was, in my opinion, what put Cold Steel on the map all those years ago.
When Cold Steel came to Camillus to make their carbon steel knives, they did not want to pay for the vast amount of steel that had to be purchased in order to have a custom steel made to their specifications.
Consequently Cold Steel agreed that Camillus could also use the steel (& pay them a royalty, I believe) but could not call it Carbon V.
I came up with the name 0170-6C, based on an almost close (but NOT) steel produced by Sharron Steel called 0170-6.
All this is historical trivia.
The real issue for those who understand is Heat Treatment!
The reason that the Camillus Beckers perform so well is that Dan Maragni set up a system of heat treatment at Camillus for the Cold Steel knives, & oversaw almost every batch of knives produced. What we learnt about heat treating Cold Steel seeped over to the Becker knives.
All that is now lost forever!
In my humble opinion, the values of the Camillus Beckers may not rise significantly in the collector market, but for those interested in a high performance user, get them while you can. Without Maragni's methods, I don't care what a future maker of Beckers uses, they will just be well designed carbon steel knives covered in powder coat!
I dearly hope I am wrong & the new maker will consider trying to improve their methods. Time will tell..............
