I was at the archery expo in Kalamazoo Mi. in Jan. and sat in on Monty Browning's lecture about arrow penitration. He covered proper broadhead selection for various hunts. I have only hunted deer and small game in my home of Michigan and I have stuck with a Magnus 2 blade 125gr. glue on tip and have become very good at making them shaving sharp. After Mr. Brownings lecture on the big game hunts, he has made me realize that my two blade isn't the 1 size fits all and I have been looking at buying a pack of wensel woodsman broadheads. My question is this, how do you guy's sharpen them? I have a lanski sharpening kit and it works quite well for the two blade. would it work for the three blade?
