Just bought benchmade 940-1. Any tips to sharpen s90v steel on a KME?
Can't agree with this more.I've done S90V, S110V, and Maxamet on my KME. My biggest piece of advice is to use the diamond stones and to use light pressure. Don't know what your preferred edge finish is, but I like stopping at the 300-325 grit range and then doing 5-10 stropping passes with 4 micron CBN emulsion. Leaves an extremely aggressive edge which seems to do very well for my EDC tasks and maintains its performance for quite a long time. YMMV of course.
Edit to add: Also, if you're doing a full reprofile, do NOT apex the edge with the 50 grit beast diamond stone. Get it close, then move on to the 100-140 grit. Trust me on this one.
Regarding your edit, do you mean, do not form a burr with 50 but rather with 100-140? What is your experience with apexing the edge?I've done S90V, S110V, and Maxamet on my KME.

Avoid the 50grit apexing and making a burr because it will cause the edge too tear out because it's too coarse a stone. This will then make edge stability issues that cannot be fixed in the later progression. That's why it's preferred to either start with the 140 or to just apex and create a burr with the 140 and the 50 to set the angle when re profiling because it hogs off material fast (let the diamonds do the work, don't use heavy pressure what so ever).Regarding your edit, do you mean, do not form a burr with 50 but rather with 100-140?
