Wyoming bone saw
I have one of these for a few years now and can't say enough good things about them. The blades are very sharp, very well made and durable. I used the wood saw blade to cut off several of my 4x4 posts for my backyard fence last week - I use it for eveything it seems. The bone blade - cuts through elk leg and pelvic bones super quick. It takes apart ond the one I have straps arouns your waist like a belt.
I can't imagine elk hunting without one - in my opinion, you just gotta have one hunting/camping.
