Same with the woodsmens. They sharpen fine the first time. After that, It's hard to keep a good edge on them. I bought a dozen of them when they came out, and all of them the tip curled over on.

When I got them, they were marked 130 gr, but weighed an average of 139 Gr. sounds picky, but if I wanted 140gr heads.....<img src=icon_smile_angry.gif border=0 align=middle>
