See I don't get this! The warranty is for damaged heads not a lifetime of sharpening service. Besides I shoot EVERY broadhead atleast once to make sure it shoots straight. They are so simple to sharpen with a accu sharp, KME, Lansky etc. I'm odd fashioned but one of the things bowhunters need to learn is how to sharpen pointed sticks!
I've exclusively used Magnus Stingers for umpteen years now and not had a single failure. With some serious abuse of hitting shoulder blades, pass through's going into trees, rocks, roots, buried in the ground etc. The worst I've seen is little chips out of the edge through all of this.
OH well sorry for the rant, go on!
