S90V - Your experiences

[Bermont River]

Not related to sharpness...but how is everyone finishing S90V? My first try at 90 and I have blades ground and heat treated (turned out pretty good for first time..63C to 60-61C final) but am struggling with the finish grind.

Tried progressing from 60-220-320-440-A45-A30-A16 and cannot get an acceptable finish. One blade is hollow ground, one is flat and the flat ground blade gets waves throughout the face. I colored the face with a sharpie and when grinding the entire blade is touching the platen but small waves appear no matter what I do. I am thinking that a mirror finish is out of the question! lol

Any suggestions or threads on the topic?

I have a Military and Southfork in S90V, and a PM2 in CTS-20CP (a close relative to S90V).

I'm not into hair whittling polished edges. I run it at 13 dps with a 15 dps micro. I normally finish it on the SM diamonds (about 400 grit). With this finish it shaves arm hair aggressively, but it's not kind to the arm underneath...

I love S90V most of the time... It works really well IMO with a coarse, grippy edge.

Two negatives:
- it is a bear to sharpen, especially to remove damage or to thin out a thick edge
- I've never seen it chip, but it will roll easily with a light nick on something like a ceramic plate or peach pit or BBQ griddle. Superblue and M4 seems to be more resillient in comparison.

It stays sharp for a loooong time during my average light EDC use, as long as I can avoid hard contacts.

This thread needs more pics !

Not great at shaving arm hair feels less than it could be at catching on finger nail cuts hard rubber and plastic bag surprisingly well

That is exactly what I am experiencing with my CPM-S110V Manix
I am used to Spydercos coming out of the factories a little sharper (tested as you described).
I resisted really sharpening it as I normally would and just left the so so toothy USA factory edge.

Glad I did. It was an eye opener.
