The sound as it went through paper was absolutely gorgeous; the sound when you dug in to the plastic was absolutely horrendous hahaha. Beautiful knife, beautiful edge!

Re: What are Matrix steels? YXR7, CPM-1V, Caldie, and More

This is interesting. We haven't talked about the matrix steels much and out of these YXR7 and HAP-5R are the only ones regularly requested but that isn't for them having matrix steel properties. Some of these aren't powder steels and some are IIRC. Are they typically good enough grain wise to not n...

Skip the Alumina and the SiC

Look into Resin bonded Diamond stones and Metallic bonded Diamond/CBN.
What do you recommend for coarse grit? I haven't had good luck with DMT.
For the edge pro, Metallic bonded CBN 125um

For freehand 400grit Super Vitrified Diamond

Finish the edge between 40um - 10um on stones

Enhance the edge with 1um diamond spray on leather

Re: S7 Large Camp Knife

Do makers even make these blades in your desired geometry? I suspect they will be made in the standard of the day, too thick over all, and thick BTE. Make one in 4-5 inch range with a high thin hollow grind and I'd be interested for the reasons you've stated. You know what, I bet you're right. Sad,...

That's like saying Blue Man Group guy 1 gets so much more publicity than Blue Man Group guy 3.

S5 and S7 both get no love.

Re: I Tested the Edge Retention of 48 Steels

Super excited to see Larrin's new steel! Reading the email updates about it, it sounds extremely promising. I can't wait to hear the CATRA results. I have a feeling it'll do very well. Thanks once again to Shawn for doing all that heat treating and grinding! :eek: Seriously, you two are on the fore...

The rumors are true, Dr Larrin has designed a New CPM stainless steel that is quite remarkable.

Excited to see how it does in testing with these two conditions .

Re: Rex 121

Some perspective just for fun. It took six high quality 2x72 abrasive belts to grind a 2.5" Catra test Blade to 0.010" in Rex 121 It took a quarter of a belt to grind a Catra test blade in 1095 Each belt is close to $10 a piece. Most steels it's knives per belts, in steels like rex121 it's belts pe...

If Sal himself finds it a pain in the rear to work with, and resharpen even with CBN, I doubt majority of customers would have better luck. I know a few of us here are sharpening and "edge" junkies, but I don't know if they'll think it profitable to produce this in mass quantities knowing that 80% ...

Re: Sal, Can we get CPM 15v?

I talked to Eric, I told him which batch he needs for the best CPM 15v performance. I characterized 5 different batches of CPM 15v. There can be differences in hardness with the same protocol based on the small variation in the nominal chemistry range. This is because small differences in elements c...
