Seems like we go to great lengths to tune our shafts to a particular point weight, but I have noticed that changing the bevel angle on a broadhead, and then sharpening over time, can turn a 150 grain head into a 135 gr, or lower, pretty quickly.
Do you buy your broadheads anticipating this weight change? Or do you think this is noise in the grand scheme of things?

Great question & you are correct! Sharpening removes metal. How much depends upon user experience vs agressive grit which altogether makes the simple jig & smooth sharpening stone much more important. I've sharpened surgical instruments since 1993 & use 500 grit belts as my most agressive abrasive. But, I've done many thousands of edged instruments & know my technique well. A jig & smooth stone is all you;ll need once your edge is set.. IMHO, Ron at KME can explain this in his sleep! Give him a call. Jig & smooth stone will remove metal in microns thereby not changing bh weight with much if any noticeable significance. Other jigs & machines work also. Alaska Bowhunting Supply sells one similar (?) as does Lansky & Tru-Angle. The many selections are exactly what make customer service so critical. Ron will tell you.

I had some OLD style 190 grain grizzly's brand new and sharpened the first time by Ron at KME and they were 175 grains afterwards. Not complaining at all. Excellent job just stating the weight loss.
