I sharpen mine. I sharpen with a carbide sharpener. I hate these for knives, but it seems to straighten a lightly dinged broadhead blade. IMHO, broadheads need a different kind of sharp than my knives. For a knife, I work hard to get "fat V" profile to give the edge a longer life. This "fat V" profile is hard to roll over. Edge roll, flat spotting and rippling(sine curve along the length) are dullness. For a "one time use" blade like a broadhead, I like hollow ground or a true V. I just take the blades out of my broadhead and work the flat spots and ripples out of them. Sometimes I use a file to nock a heavy burr off like when I hit metal in a target![:@]
