New to the realm of net blade forums and find that the previously mentioned light-weight folding saws are most appealing if I felt I needed one while back-packing but likely wouldn't carry a saw while hiking as a decent fixed blade knife should suffice.
Still, have gotten a ton of use out of my 'lil 15" Sven saw of 32 years and really should replace it's blade already. When Winter camping in sub-zero U.P. (Upper Penninsula of Michigan) it was invaluable in procuring enough dead Maple lengths (can only drag so much length and weight of wood when on snowshoes in a swamp) to get thru the lengthy darkness. Sure , could just stay in the down bag from 1600 to 0800, but sixteen hours of anything gets tedious.
Now, am a bit lazier and use it for removing logging road obstacles in B.C. while driving to a trailhead, dropping logs to keep ATV's off legally restricted wilderness hiking/horse-packing trails and most of all to just buck slash to my pick up's bed length so as to have an early-Spring's night long drinking fire amidst the snow at elevation to keep the dog warm and stimulate my memories of similar evenings while we listen for the coyotes and await sun up.
Of course I carry chains and have the most excellent Bridgestone "Revo" tires on my Tacoma, as well as a jerry can of gas, water, clothes...All the usual **** except cell phone, GPS or anything except DeLorme mapbooks for WA, ID, MT, OR and BC (Oregon made "Benchmark," maps and road atlases are far superior) but I really should carry a decent bucksaw in the truck. "Sawvivor" looks promising but I'm sentimental about the baby Sven. Sure I'll change my tune when I get into a real Winter bind. Course, if that happens a Husky or Stihl would likely be of the most benefit.
New to this forum and don't know the rules and see that this has turned into an off topic book length production. Please correct or offer suggestions if indicated. Getos.
