To me the Corona is the best thing going on in the folding saw department. The only other saw I really want in my backpack is a Sawvivor but they are not being produced right now.
The Corona only cuts on the pull stroke but man does it cut. If you like a saw it is the one to get. I have seen a few post to this thread that states that they do talk about saw's often. Not compared to other survivalist sites I visit but yes on occasion they do talk about them as I have posted on 3 or 4 of the threads.
I notice they have a axe, hatchet, and tomahawk (or something like that) forum here but that does not include saw's, maybe in the future.
It seems like only cutting on a the pull stroke would be a bit limiting, but that is without trying it. Needless to say, you've got me curious.
Based upon the price point, as I stated, the Schrade and the Gerber cut tremendously, both ways and are lightweight too boot. Add in the fact that they can be carried in your pack or on your belt with a chopper and you have the tools necessary to make a relatively comfortable, cozy camp anywhere , any time.
