Don at Four Dog Stove (http://www.FourDog.com) reviews key features that make Bob Dustrude's 21", 24" & 30" folding bow saws his #1 pick. This is the only bow saw you'll lilkely ever need, because it is built to last for decades, and you can replace the high quality blades, as needed.Made from an extruded aluminum frame, with channel lock construction, and a leveraged-tension blade design, you'll get the perfect blade tension, every time.I've known Bob for a while now--and he's a colorful fellow, with a great zest for life, and an eye for making quality products. As a WWII fighter pilot, Bob knows the value of a good buck saw, that won't let you down, doesn't weigh much, and packs flat. You can even set this saw up with one hand, in case you need to do that in an emergency, if one of your hands or arms is broken. That's a great feature for a survivalist-type saw.Bob still making his quick buck saws--and he's still going strong, into his mid-90's in age (at the time of writing this). So do yourself a favor, and watch this video on Bob's saws, and check them out on our website. Even if you don't need a saw like this, it's good to know that people are still making good quality products like Bob's Quick Saw, right here in the USA.
