Thanks Dan. I didn’t heat the grips up but at the moment they are soaking in a 50/50 mix of warm BLO and turps. It is a nice warm summer’s day here and the jar with the knife handle in is out on the back deck. I’ll wait till the day gets cooler before I remove it. I assume that a few hours in the oil mix will do no harm. Note grain on grips after freezer time.
