RE: NAP Pelvic saw
Buddy has one and we used it last fall for a few deer, it worked just fine. It works just like a chain saw(no not the gas kind), slicing a thin line with minimal resistence very quickly. I will say having to thread the handle though the first time made me wantto reach for theSagen Pelvic Saw, but by #2 and #3 it wasn't that big of a concern. After 2 deer the chain it uses was severely kinked but it proceeded to work for more deer. It cleans up suprisely well I thought.
All in all not a bad product. I still prefer my Sagen, more elbow grease required but operates just fine and no need to thread the needle!
