Because pocket saws don't cut it
Even if your pocket knife is as sharp as a samurai, nothing beats cutting wood with a saw. Some multi-tools come with a saw but if you want a better performing saw that's also easily packable, check out the Boreal21 Folding Bow Saw. It folds up easily and unfolds in seconds without sacrificing sawing performance.
The Boreal21 is designed to meet or exceed the performance of fixed frame bow saws and comes with a handy leather or canvas sheath. Made of anodized 6063 aluminum frame, fiberglass reinforced nylon handle, all stainless steel hardware, hardened and coated saw blades.
This was a successful kickstarter campaign and is now available for purchase from Agawa (link below). People don't usually carry saws for camping because they're bulky and hard to pack. With folding saws like the Boreal21, you can easly carry one with you.
