All good advice! Shoot n sharpen!
The "variable" aspect has been noted. I had at one time, being severely sharpening impaired, used a Redi-Edge tool...man I could get stuff REALLY sharp... but would have sparse blood trails... go figure.
A good man with far more experience killing stuff than I pointed out that my head was likely getting dulled going THRU the deer! :eek:
I investigated that sharpener...it was setting the "edge" at 19*! That was why it seemed so sharp, but it was such a fine, thin edge, it dulled on it's way thru the deer!
Now I use KME sharpened heads and keep the touched up to their intended 25* angle with the BH Pro...
They will still shave hair when they've gone thru a deer... but they are not as sharp as when I started so they go into the bottom of the quiver for re-touching!
