As I've been following this thread all I could think about was if I ever purchased a worked spine razor and what it would do to my Kanayama. *shudders*

So, just last night I decided to revisit my Dovo Micarta that has an etched spine. Now my Kanayama has a nice zebra look to it. lol I can't see where it caused any damage to the strop. This doesn't happen when I use my SRD red latigo strop. I guess the Kanayama is just soft enough that little things appear.
