I have dressed several 30+ moose over the years, and the advice here is right on the money.
Bring rope. I have 3 knives with me and a diamond sharpener. I use a Puma bowie, shrade lockback [bearpaw], and a Muela with a 4inch blade with a gut hook. Bring rope. I also have a Wyoming saw. Bring rope.
It is a large job, even if you kill near a road. It's tougher if you are miles backand if the snow is more than a couple of feet deep it is tougher yet. Bring rope.
As already stated, you'll need rope to tie the legs out of the way, avoid cutting hair, try to "work from the inside out"to make things easier and have your knife last longer.
You should also bring rope.
you'll need it to hang quarters, drag quarters, or lash them to a packboard, horse, quad.or boat.
Here's one from last year. My buddy's first. He called it in himself.
This year I'm gonna try this technique. I already do this kind of thing for bears.
