I saw a nice looking sgian dubh on Ebay the other day...wood handle, hard sheath...but it had a stainless steel blade.

I've used knives all my adult life and can sharpen a good blade so that it is "scary sharp."

But I've never used or even handled a stainless steel blade. Are they hard to sharpen? Will they hold an edge? I'm guessing they're not premium but thought I would ask.
