I can only give limited feedback, as I am not a knife tester. I can give my EDC impressions. This is going to sound weird, but I agree with what Johhny said, it has a different smell when a patina is forming. Reminded me of using a cold blue kit to touch up old firearms. Not important, but an observation.
As for the steel, one concern I had was being able to sharpen on my old fashion natural stones. I have come to like translucent stones. For the GEC 1095 they did an amazing job. I was initially worried that the O-1 would damage my stones, but Frank (
knarfeng) explained to me that the difference in steel composition was not enough to form carbides. I believe it is the super hard carbides that can really tear up natural stones. I am sure Frank can explain it better then I. I have read for hours (days) in the knife makers forum about steel composition and so on, but I can't explain much of it myself.
I can tell you this, I have only touched up my knife once since I received it and it was just a light grazing touch up on the arkansas stone. It is a pleasure to sharpen and I feel like it has held a good toothy edge longer then I was used to with my 1095 GEC's.
Here is a 100x microscope view after the first touch up and a little use, including cardboard.
Even though my EDC feedback is far from conclusive, I know the edges I start with do not have a bur and are finished to about the same level.
Your question concerns me, almost making me think GEC is having a second thought on the O-1. If they did, I doubt I would be so excited about the next run. I was initially interested in these. Then I received mine and I was very interested and impressed. After use I want to buy a few for myself, my dad and my brother and a good hunting buddy. If they go 1095, IDK. I do love my drawer full of 73's in 1095, and the O-1 is kind of a real attractive part of the package.
Thats the little feedback I can give.
