Hey guys.

I'm thinking about rounding the spine on a knife of mine (cpm m4) and I'm wondering what the best method is.

I don't want to scratch up the sides, and I figure that powered equipment (Dremel) may be a bad idea? Or not...?

Any help is much appreciated.
 
I have done this, with 8cr13mov, with a mouse pad and sandpaper. It takes a long time but I started with 60 grit and ended with 2000. With various grits in between.
 
A belt sander would be best, use a slack belt-(no platen behind it) hold it by the tip and handle and just roll the spine back and forth, to practice use a paint stick- there free to use up, round the edges on that until your comfortable- and bingo your home free
 
On some of my knives, I just wanted to "break" the edge barely take off the sharp corner, but still keep it square. I just used sandpaper and a sanding block.

For a few others, I made the spine half round. I used a slack belt as Bowexpress describes, and used sand paper and a block to finish it. I've done this to my Sage I and Kershaw Chill. You can do a half round without a belt sander, just start out with coarser sand paper. It will take a little longer, but you have better control how much material you remove. Power tools make the job faster, but they can also can screw it up faster.

You can put some tape on the blade to help prevent scratching.

What knife are you rounding the spine on?
