Sorry if this is posted in the wrong place. I'm looking to narrow the handle on a Ranger RD7. Overall, removing an 1/8 to 3/16. I ground a choil into a BK7 awhile back, but it took a lot of effort to restore the edge. Really don't want to screw up the temper again. I'm new to this, so ANY advice (tools, techniques, etc) would be very appreciated. Thanks, Will
