First I tape off everything that I don't want scratched with the file. Then, I reshape the handle with a file as necessary. *****Ultra care will be needed near the ring, if present. You won't believe how easy it is to chip a big hunk of ring away.******* Here that isn't a worry. Keep the file away from the pins as deep scratches in the pins are hard to get out. Then use sandpaper starting with 80 or 100 grit and working up to 220. I've heard guys here go to 1500, but I can't see the point of that myself. JMHO. After 220 grit paper I switch to Scotchbrite pads. (Maroon, Green, Grey, White) Scotchbrite pads are great on knife handles and blades too. Then I hit it with Watco's Danish oil. For the first coat I apply every few minutes for ~1 hour. Then let it sit till its stickey and wipe off. Over the next few days I do a few light coats, putting it on, waiting 15 minutes, and wiping. Voala. Boy that makes those curly woods pop!!!!! Then occasionally I dunk it in mineral oil for 24 hours, drain it for another 24 hours, then wipe.
