Question on RAT-7 D2 heat treating problem

[SPERRON]

I read on another forum that the early RAT-7 D2 knives suffered from some sort of faulty heat treating which left the blades more brittle than they should be.

My RAT-7 has held up well, but it did get a small chip in the edge that I had to sharpen out. Can anyone elaborate on the heat treating problem and when it was corrected?

 

[he who say]

what did you do to make it chip?

 

[SPERRON]

I'm not exactly sure. I used it on an outing then went to sharpen it and noticed the chip. I did some light splitting and stick sharpening, that's about it. I may have hit a knot when splitting.

fwiw D-2 and convex edges go together well, and that'll help prevent undue chipping.
