BM 940 dull already

Learn how to sharpen on inexpensive knives. And once you hey the hang of it so your expensive knives. Else your just gonna scratch them up etc.

Diamonds or cbn are recommended to sharpen steels like s30v with a fair amount of Vanadium because most other abrasives are not as hard as the Vanadium in these steels. I find SiC (silicon carbide) stones work very good too. Ceramics will work but will load up and require cleaning often when they do.

Kme and edge pro are going to be nice to use and have many stone options. These will make a v grind. But learning freehand is also a very good option. Just won't be fairly exact. This method does a convex edge.

Check out the sharpening section on the forum and read up. Check out the stickies too. Also many tutorials are on YouTube.

Yep, I really like CBN for sharpening s30v. I've got a Gritomatic 400 grit that works great on super steels, it's got enough bite to do some minor rebeveling but if I ease up on the pressure it can also leave a nice toothy edge followed by some stropping. CBN stones aren't cheap, but they don't load up and/or dish out like alum oxide either.

BTW, was the steel on the 940 154cm or S30V?

S30V

We only used our cable knives on those ties as last resort. Jameson 32-24J. Some kinda cryo tempered steel. Hard as a rock, kept a razor edge for a long time & plenty of abuse. I still have a few laying around.

I’m pretty sure you have to buy a membership. Which level, I don’t know
