I helped a guy out for sheep in area 5 about 13 years ago. At the end of August and early sept all the griz we seen were above timberline eating moths. Seen 8 at the same time on one mtn. Didnt see any sign of them down low.
See bambis post above, these saws are cheap, work better than anything, lay flat against the back of you pack and light weight. Cut horns off in a few minutes.
Cutting the horns off is the only use for a saw as far as butchering goes. All else can be done with a knife.
