Ga Red how much is it worn down?

On folders if they don't have a hollow grind they can get sharpened down to where they are quite thick and sharpening requires grinding a new bevel or spending a lot of time hand sharpening a new bevel. The reason being is as the blade wears down it gets thicker and you might tend to hone your edge at a sharper angle like 30+% and it doesn't cut as well at that bevel. How often do you sharpen it? CPM 3V shouldn't need to be sharpened very often.

That said, CPM 3V handles a very shallow bevel like 15 degrees and doesn't fold over as it is a tough steel at RC 60 hard. I have a hard time thinking the heat treatment on a folder would get dull after a few months easily. It is just something I haven't heard of with the 3V alloy steel. I hope you haven't used a powered sharpener because they can heat up the edge and make it softer.

That being said, who is the maker and do they have a decent warranty? Not many makers use CPM 3V and though it isn't stainless it is 7.5% chrome and corrosion resistant. I have used it a little with some 1/8" material and sent it to Peters heat treat. It is to me an excellent steel that needs to be used by more knife makers. It is better than A2 and many of the stainless steels in cutting performance. Tricky to heat treat though.
