If you're main goal is to flesh coyotes is there any advantage of of having two different fleshing knives or would a guy be better to get one size and get proficient with it? Then what length should a guy start with.

10” knife is all you need.

One size,10-12" curved blade for larger animals,and a stirrup flesher for the small critters and touch up on clean skinned beaver when boarding the beaver.

Thanks guys, bctomcat what brand is the stirup flesher?

Caribou Knives, small pelt flesher.

Thanks I'll look into getting one.

Post makes a stirrup flesher that looks very similar to the one shown.

Post Flesher

Was surprised when I looked this one up and they wanted $72.00

Quality of the steel makes a difference.

I have one of those stirrup shaped fleshers, it was like a cheap $10 weibe and doesn't do a thing to a pelt as far as removing any sort of flesh. I know it's of low quality material.

A question, is one side supposed to be sharp and the other dull?

With the weibe yes. With the better caribou flesher both sides are sharp.

One side of the Post that I have is considerably sharper than the other side.

Thats a good one.I have a zeph,also a good one.You can use those for frost scraping if you keep them sharp.
The cheap ones are next to useless.
