I've had this big old saw for a while now, I found it in a ReStore for like $10 and have been using it for firewood cutting intermittently ever since. Because of it's somewhat crude construction and lack of any markings whatsoever I initially thought it was home made but after closer inspection I don't think it is. It's made of two pieces of heavy steel piping, weighs about 6lbs, and the two sections of the frame can be adjusted for different levels of blade tension (maybe different lengths of blade?). The blade is a whopping 42" long and is much taller/wider than any other bow saw blade I've seen Never in my life have I seen a bow saw this large, so I thought some of you guys might know a thing or two about it or at the very least think it's a cool tool. Because of it's weight and bulk it's kind of tricky to use and absolutely requires some sort of sawbuck. This means I don't really like it for a "field" saw for car camping like my other larger bow saws, but for home use where I can strap down the wood at a proper height it works quite well. Great alternative to a chainsaw when I need something quieter/less fiddly. It seems to cut faster than my 50" crosscut saw with a more conventional design and is certainly faster than the "little" 30" bow saw I normally use, so it's quickly becoming a wood shed favorite. What do you guys think?
