Does custom or factory hold any blades fitted with these steels?

If not any bladesmith are would be prepared to make me a nice blade with one?

This piece of text come right from the Crucible-site. This is not my only source, and I'm aware of the flaws of those steels:


The “Killer-V’s” now include CPM 3V, 9V, 10V, 15V, as well as CPM M4HCHS with it’s 4% V. This family of high vanadium tool steels offers superior combinations of toughness and wear resistance as shown in the accompanying comparagraph. Our well-known CPM 10V has four times the wear resistance of D2, and CPM 15V is 50% more wear resistant than 10V. As a matter of fact, CPM 15V has the highest wear resistance of any tool steel, approaching that of carbide, but without the risk of brittleness. The latest addition is CPM 3V, which at HRC 58/60 provides impact toughness approaching that of S7, while still offering wear resistance higher than D2. Crucible continues to develop specific high vanadium CPM grades to meet a variety of wear/toughness requirements.

Read the last lines of those texts... They are working on something. I have heard it wil be CPM125 or S125 ( not quite sure of the excact names, number is 125, that's for sure) and a second one: CPM-3V-MODIFIED. Any insights? Other imporant general news is also welcome :-)


Thanks for your attention
 
Phil Wilson has worked with many of the CPM steels including 3V, S60 and S90V, CPM-10V, and 15V. He is an engineer with a very sound knowledge of blade properties and materials as well as understanding of geometry and aspects of knife performance such as edge holding and functioanl durability. He does his own heat treating and runs them all very hard 63-65 RC except for 3V which is left softer to maximize the toughness. He has also made knives out of CPM125 which you ask about in your other post, at 65 RC and has seen performance in edge holding well in excess of 10V. Drop him an email at seamount@bigplanet.com.
