I bought a cool little boot dagger with 440c steel for $15. i can't get a good edge on it with my sharpeners because the factory edge needs to be reindexed. When i look at it with a loop it squiggles off center and at the tip the two edges don't line up. I need someone to center the edges and put symmetrical shoulders on it, so i can touch it up periodically with my Spyderco Sharp Maker. Does anyone have a guy in thee Boston area?
