RE: How sharp is sharp enough?
Here is a thought. There are some very serious successful hunters out there that swear byusing a file only method of sharpeningbroadheads. What they believe is that after the head has gone though the hide and the first set of ribs (assuming you hit ribs), thata scalpul sharpened head will be dulled significantly. A surgeon only uses one scalpulfor one cut from what I am told. The file sharpened head although somemay call it dull compared to a scalpul sharpened will retainit's sharpness better.On the file sharpened head there will be microserations (can not be seen by the eye).
Personally, I have never tried it, but there are some that swear by it.
