Very cool - Why ? I shoot a trad bow, and I like 3 blade broadheads and I've used Thunderheads in the past but I like the idea of cut on impact. However, I use a thunderhead as a measure of what "sharp" is and I cannot get a resharpenable head "sharp"

Are these Thunderhead sharp ? If they are ........ I might be shooting them this fall because I've read on them, I like the concept, and blade thickness, etc etc.
