Personally I Suck big time at sharpening knives, I just cant get the technique down.

I Wasn't Too worried since 4 of the knives were under 20$ in cost and easily reobtained if ruined. The Buck has since my purchase shot up in price big time so that made me a touch worried but not much. The big issue was the benchmade which was a costly knife that I carry and use every day and sadly thats the one that suffered the most.

Strangely enough I did send the Presidio Back to benchmade for a sharpening and they put a awefull uneven very very high angle tiny little edge on it. Very confusing but He did put a nice little steep even grind on it even if the very very first quarter inch at the hilt is a touch off.
