The problem is what works for me and what I like might be something completely different for you.
The best one that I have found is the larger Wyoming saw II. It is light and flat enough that it will fit in your pack or you can strap it around your waist. It has both the bone and wood saw goes together quickly and you can replace the blades. There is also a smaller version but I have a hard time with it. It has a short stroke that I don't really care for.
I used the big Wyoming saw on our moose hunt this year. If you need that much saw it's a good one. It does a good job on wood too with the right blades.
The Gerber folding saws work ok for smaller jobs. If weight is an issue I usually go without a saw. I can cape and quarter game without a saw. I have a Havalon Barracuta that has a saw blade for it but I haven't used it yet. I sometimes take my Cabelas Alaskan Guide 183 knife. It has an S30V blade plus a saw/guthook blade that works well as a small saw.
I've gone away from having a saw in my pack for weight saving. There is nothing that I cant do with my knife. I dont hunt anything larger than elk sized game. Most pack outs are boned out meat. When I am closer and keep rear quarters on the bone I'll cut em at the knees.
Depending on what I am hunting I pack a Gerber saw that has a bone saw and an extra wood blade. It works pretty well for the price point.It doesn't have great reviews but I have used mine with no issues.
I agree with all the above and I am very handy with a knife also and can do all with just a knife. I have had a few of those gerbers and they all broke in my hand or in a friends. My good buddy has the wyoming saw and it is nice but find we typically keep it in the atv or the truck. Still looking for a saw.
I use a small grizzly saw. Its light, maybe 7" long, slides in a small plastic sheath, and I've been using it for 10 years without an issue. I only use it when needed while in the field and have never had an issue nor see why anyone would...
