Some knives I get have a groove in one of the bevels

[bladeprince]

While inspecting and sharpening some of my knives, I notice what seems to be a "groove" or "concave" area along one of the bevels. One side sharpens and feels smooth and the other has the "groove". After usage and some sharpenings, it will get smoothed out but I don't understand why it's there in the first place. Anyone ever notice this and know why it's there? Are they using one of those carbide "V" type sharpeners. It think I have seen the same thing after using one of those.

Regards and thank you.

I can't picture what you're describing, but in any case, I doubt any manufacturer is using a carbide sharpener.

New knives often have less-than-optimum factory edges. Sometimes the bevels aren't even, sometimes they have a wire edge, sometimes the edge is too brittle, and sharpening it back gets you to the undamaged steel.

It's always a good idea to sharpen them before you use them, especially since you may want them to cut in a way for which they weren't sharpened by the manufacturer.

For example, they may have a strong working edge when you want a thinner, slicing edge, which you feel the premium steel will support.

Somes knives have hollow ground edges as they were sharpened on wheels. This leaves the edge very weak and they tend to take damage quickly.
