I got my Stay Sharp tool in the mail the other day. No, I didn't win it at the drawing that DIY had. I bought it online. The reason I got it is was because I was having a heck of a time trying to sharpen the blades on my NAP Killzone broadheads.
Well - I took one apart and put it in the tool according to the instructions and within 10 mins on an arkansas stone, I had the 2 blades razor sharp. This is a pretty cool little tool.
For fun, I took the main blase off a Magnus Stinger BH and put it in the tool. Within a couple mins this blade was also super sharp.
The only drawback I have now is I need a larger stone. My 1 1/2" x 4" stone works but a bigger one would be even better.
