Hello!

I've got a custom in magnacut with a one and a half inch section that just won't take an edge. Did a full reprofiling twice and still the same. North of it? Shaves. South of it? Shaves. But this one and a half inch strip just at the start of the belly of a large camp knife... just looks like the steel crumbles away there at the very apex. I can see under light that right there the edge looks irregular even though I've gotten a burr on it twice and carefully deburred.

How does that happen? Burnt edge from grinding? Some weird HT issue?

HRC estimated about 61-62.

I don't think I'll return or even complain to the guy about it. But I'd just like to know what's going on with it or if it'll get better!

Thanks!
 
Hard to say what is going on. Photos would help a lot.
Could be an isolated place that had large grain growth

I would contact the maker. He might have an idea what is happening, and likely would make it good.

Here is another thread on a similar issue with some pro-cut. Not sure it could l be the same issue or not.

Starting thread to talk about....
Has anyone used This yet?

Changing Title to Dialogue....
 
All steels alloyed with moly are prone to heavy oxidation if not properly protected during heat treating. My guess is that the maker had a pin hole in the stainless foil.

S stacy no, these two steels are not even remotely related and it’s a totally different problem.
