what chance is that really taking? there is much virtue in sharpening your own broadheads, knives and other things. it's a source of pride among people who appreciate what it takes, and what it means, to make something really sharp and then actually use it. besides that, sharpening your own broadheads is one small way to put more or yourself into the hunt. it's damn disappointing that more bow and arrow hunters don't do it nowadays. buying new blades is surely a lot easier.
Jake_C, I've never resharpened a replaceable blade broadhead with anything because I've never hunted with anything but one piece heads in the last 33 years, and I've been sharpening my own shit for at least that long. give it a try.
