Working with 10v Steel?

[Daniel Fairly Knives]

Thanks in advance for the help! I'm working on some Framelocks with CPM-10v blades and need to figure out my game plan.

1. How hard is it to grind after heat treat? I know finishing is tough but what about grinding the whole blade after heat treat? I make folders and like to grind after hardening.

2. Can 10v be double disc ground after hardening?


I'm considering sending my blades off for heat treat then to double disc grinding before I do the final pivot hole reaming and bevel grinding. Good idea?


I understand 10v is very stable during heat treat but with these blades being for folders I feel they should be ground parallel after heat treat... also these will be chisel ground which can sometimes effect ht stability a hair (warp) which can be a lot on a framelock.

Do I simply need to do everything before heat treat and expect to lose a few to warp... or fix them with a disc grinder and measure to keep parallel? ? I normally hand lap my folder blades but I doubt that will touch the 10v.

I have a test blade going with complex chisel ground Hira Zukuri inspired geometry. I'm going to heat treat it myself to see how it does. My kiln goes to 2000 so I'll do the lower austenitizing temp and see... I'm sure I'll send off the blades though as I want them at the higher hardness/temp.

Daniel,

I am also very inetersted in this as I am getting ready to do the same in 10V as well as a small bit of S110V.

^ I'll be reporting back soon with my findings but for now... bump!

Does anyone grind 10v?

I have 10 knives that just came back from heat treat. I'll be working on them this week. I'll report back.

I spent some time grinding a few of the 10v blades that I got back from Peters last night. They are hardened to 64 hrc. The actual grinding was not necessarily hard but it does take brand new belts. Belts that I could continue to grind with on hardened 3v wouldn't touch hardened 10v. I was using 120 grit blaze belts and I could only get about one blade cleaned up per belt. 120 grit equivalent 3m "gator belts" did very little to the hardened steel. I'll start in at 220 later this week and will again report back.
