Have you done this with a Dremel? That tool, despite it's small size scares the crap out of me. It's ability to do unbelievably precise work also means it can do much damage when in the hands of me.

When I first got my Dremel I dremelled about everything in the house. I wanted to polish the ferrel on my pool cue. The compound that came with the Dremel was too coarse and I dug into the ferrel too much. The damage isn't bad and it was my spare shaft but the capability of the Dremel got my attention. I don't have a spare Sage4 so I don't know.

I do know if I tried it I'd use some of the DMT diamond paste instead of the Dremel compound.
The scratches are actually a feature of the knife that makes it look capable IMO. Plus I wouldn't try the Dremel on the ti unless I could try it on something else first. I have all the polishing felt things but even with the proper tools I'm too scared to try it on the knife.
I wonder if there is a Dremel forum for questions like this. 
EDIT: Guess what, Dremel has a forum. I just checked.
