Rockwell Hardness of Benchmade 950-1001 CPM-M4

[asilomar]

Does anyone know the Rockwell Hardness of the Benchmade 950-1001 Rift with CPM-M4 steel?

Thanks!

I believe the BM website stated 60-62 for another model in CPM M4.

My benchmade goucho tested at 58 and was retreated to 65.

Its not nearly hard enough. In fact, I've heard the HT is so poor, you should def sell me yours as soon as possible....

Ok that or I just missed out on that knife and I'm still butt-hurt over it lol. I have an Lum LFTi in same steel, was curious myself. Sending it to Tom Krein for a regrind here shortly, think may see Phil Wilson next for a re-HT as well. 58 is piss poor for M4.

Ryan, who did your HT?

My 950-1001 seems softer than my Spyderco Mule (tested at 62.5 RC) and my Spyferco Gayle Bradley in CPM M4 when I sharpen it and in edge retention. I am getting mine re heat treated song with my Bradley to 65 RC or so though anyway to see just how much performance you can get out of CPM M4, but I wil report the factory hardness after it's tested.

I agree m4 needs to ramped up by benchmade to atleast 61-63

Phil Wilson did mine. I havn't had any chipping or any other trouble. 65 seems to be a good hardness for m4

How's the toughness at 65?

Phil reported that at those hardnesses he is seeing wear resistance in the S110V/S125V category, If I recall that correctly. I don't want to put words in his mouth. That's pretty impressive stuff if so.

I haven't seen hardness numbers or tests but it should be stronger than any stainless steel that's run like that. It should be a pretty tough steel even at those RC's.

I just checked my email from Phil & the Goucho was 59 not 58. Sorry for the mix up.

My benchmade goucho tested at 58 and was retreated to 65.

58!?

I'm glad you got it rehardened. This steel really performs at 65. And still tougher than most 60 rc stainless steels, I've found.

Sorry to bring this back from the dead, but would it be more worth while to send an LFTi back to Benchmade for Lifesharp and request a re-heat treating and sharpening or simply send it to someone else?

cotdt I tried to PM you but could not.

i sent Phil my 710M4. it tested initially at around 61. brought it up to 64 or so and it's been fantastic at that hardness

Benchmade definately will not heat treat your knife to a higher hardness. They will sharpen it for you though. If you want the hardness raised you will have to have a custom maker do the job. Check out the link above to get you started.
