Tell us about the handle. It looks like a sort of marble. Did you wrap it in hemp cord soaked in epoxy (or CA) and then sand it?
i wrapped it with hemp and then saturated it with CA... knocked down the high spots with 220... 2nd coat paying very close attention to the ends... knocked down again... 3rd 4th and 5th coat.. then sanded with 400grit...
i will do one more coat with CA and sand out to 600-800 then polish with jewellers rouge or equivalent.....
it is a very very nice feeling handle... very secure grip.. very "warm" to the touch... almost like a leather feel.... i will try to find a thicker hemp cord to use on another homemade in need of a wrap.....
