Trigger, I've been watching Black Bear Forge, too. Is he in Colorado? Filing the Old Hickory to get primary bevel might be overkill and take off more steel than you need to. A friend carried a file on his hunting trips to quick sharpen his gutting, skinning Old Hickory knives but they wore out sooner. If you have a strip sander 120 - 220 grit belts will do a quick and precise job. Or diamond hones. I like Spyderco TriAngle sharpening system with diamond and brown, white and super fine ceramic alumina rods. I make my own blades of O-1, 5160, 1095 alloys. I have avoided stainless because I do my how heat treating. Good to keep knives out of those who would abuse them like washing in dishwashing or throwing together in a kitchen drawer. They make plastic slide on protectors. I don't store my knives in their leather sheaths except when wearing.
