As for quality, I have been told by friends that ultimate survivals Saber saw is second to none. It's just way too big for a PSK unfortunately. I always carry a Gerber exchange -a -blade folding saw which is outstanding for my sawing needs (the bone blade is what I tend up using most for hunting) and usually does what an axe can do at a fraction of the weight. It is impractical to always have it on my belt however, especially when in uniform.
