Had a question. Can you use a strop/water stone to sharpen a Victorinox Swiss Army knife, obviosuly same stuff to do a straight razor (kill two birds with one stone)? I read some things about having to keep a certain angle. I'm not sure, it seems like the grit you need for a knife is coarser. Could anyone lead me in the write direction, including how to directions and what to buy to do it. Thanks in advance.
