Hi All,
I picked up some Shapton Glass Stones (500 - 2,000 - 16,000) and an Atoma 400 at Christmas. So far, so good.
A friend asked if I could sharpen his hunting knife; it turned out to be a Gerber Mini Magnum from the 60's or 70's in M2 steel.
Now, the edge was pretty much gone so I jointed it (Harrelson Stanley method) and started to work on establishing a new relief bevel with the Atoma 400 at roughly a 15-17 degree angle, not a problem.
Now the problem, trying to establish the apex/cutting angle with the Shapton Glass Stone 500 at a 23-24 degree angle. It's not happening. I'm doing what I've done before and I can't cut paper well, can't catch my thumb nail well, nothing. Out of frustration, I dulled two kitchen knives, and re-sharpened them using the above method, no problem.
Can M2 steel work harden over the years?

How I did the above sharpening:
Sharpie marker used, I'm hitting my cutting edge.
Atoma plate - used edge leading strokes
Shapton Glass Stone - used edge trailing strokes
Feel free to share your insights or wisdom - I'm lost here, first knife I can't get sharp - worse part, it's not mine.
Thank You- JT
