For years, I have never been able to get a sharp edge using a whetstone.

Especially with Swiss army knives.

Can someone help me?

Thanks,

Swiss Army knife blades are stainless steel I think.
Anyway, cut into the stone at about 30 degrees, alternating the sides of the blade.
You can hone the blade on leather. I used my boots. Should be something on Youtube.
I think the main issue people have is maintaining the same angle, but there's nothing to do
about that except practice or use an angle gizmo. I could shave with my pocket knife.
Stainless steel take 10 times longer to sharpen, so don't use stainless steel blades.
