Roland s110v isn't hard like the rex 45, it's in the very low 60s HRCferider wrote: ↑Mon Nov 05, 2018 8:52 amI still think the video above (steel on brass) shows that Rex45 is harder than RexM4, not tougher.
So, if you want hard on your PM3, go with Rex45, or - more affordably today - S110V. If you want tough against chipping, you could go with CPM CW (tougher than 4V), or the still available s35vn.
I have 4v in the Manix 2 that is still available, and I _love_ that knife, but compared to my Rex45 knives there is more sharpening involved.
it's just packed at high volume with very hard carbides that are harder then the steel.
That makes it cut longer but has nothing to do with staying sharper longer, aslo it increases the brittleness so it won't do well on the brass.
If you open a can of food with s110v it will look like a saw blade.
Rex 45 will not. Why?
It's harder yet more stable thanks to having less carbide volume and finer carbides.
