Those pics of your Turtle are absolutely stunning,

. Nice pick-up of a sweet knife.
My F95T is older--as in pre-R series--with SRBS, but not of the same vintage as yours as mine has jimping and M390. I have two Bears in S30V, though--the NeOn UL that's being discussed here currently and my F3 Python--and Shirogorov does a great job with that steel. It takes a wicked keen edge easily and keeps it much better than iterations of the same by other makers. It comes back great, too, with stropping or a light touch-up with The ShrpMaker fine or ultra-fine rods.
I've mentioned before too how my SRBS Turtle flips much more authoritatively than its MRBS F95R brother as well as being more drop-shutty. On the other hand, the MRBS knife is smoother, and flips easily with less pressure and a lighter detent.
