Woodsman Elite or 4 blade Stinger

[Charlie Lamb]

I'm not up to date on the current KME price but I can tell you that it is a great investment. Get the
knife sharpener and you can fine tune every hunting knife you have as well as your kitchen knives and all broadheads except 3 blades.
 
Heck I even get anal and sharpen the blades in my box cutter in the shop.

Not only can you get an awesome edge on those Stingers, but you won't be removing very much metal to get it done. That extends the life of the head exponentially.
