I'm always ingtrigued by the Silkys but the spendy price makes me wince. Someday maybe.

On the more economical side, I have a Bahco folding saw, the Laplander I think, that I am quite pleased with. The blade is thicker and stiffer, so unlikely to bend, and very sharp. The only glitch is the little plastic unlock button snapped off years ago, so I have to reach in with something to release the metal tab. A minor pain but even a twig would work.

I also found a bunch of Coghlans folding saw blades on clearance for $5 each. They're actually not bad. I'm going to fashion a short fixed handle and a blade cover from scap nylon for ultralight use.
