Just went to this year but highly, highly recommend these. And sharpening them is super super easy. I shot my buck with it this year and it stuck 6 inches in the ground. Pulled it out, cleaned it up, sharpened it on a 12" mill bastard file just laying flat on a table 3 initial strokes forward with a good amount of pressure on each of three sides and then pulling backwards at about the same pressure with 3 strokes on each side and then turn it back to normal cutting or forward direction of the head flipping it each time with progressively lighter pressure about 6 to 8 times on each of the three sides until you're basically just pushing it with just the weight of the broadhead itself. These are very sharp at this point. I then use an 800 or 1200 grit diamond flat bar and lightly do each side. That's it. I slap a little mineral oil on the head, run the threads through some old bow string wax and screw 'em back on for the next deer. I also spin check them to make sure but so far, these are super tough heads. VPA 150 3 blades. Don't discount the three blade heads they fly great and IMHO, open up a bigger wound channel overall. About 2 or 3 times and you will be an expert at sharpening these. You can feel the sharpness but I take light rubber bands and stretch them between my thumb and forefinger to put the band at just slight tension and pull the blade over it. The rubber band should snap cut right away. I also shave my arm hair but that's not the "OSHA" approved method!!!
