Hmmm. I suppose I need to give it a shot too now. I don't have a shop of a vice though. I suppose I could clamp it down and take the ramp down just a touch proud of the spine and finish with a hand file to make it nice and flat. While I'm at it I might as well round off the peak where the spine goes into the swedge and then grind off the little nub at the front of the handle. Doing all that means I should strip it but first I'll need to etch the logo...
