Forget wire-saws. Yes, they will work if you use them correctly, but nobody does and they always wind up snapping like a dried-out Dollar Store toothpick. Not so with the Short Kutt! This pocket chainsaw is built for abuse and use by the dullest blade in the shed. It's assembled in seconds and can be easily placed back in the can for convenient storage. It is used by the U.S. Military (which should tell you something) and is ideal for Homeowners, Hunters, Campers, Backpackers, Fishermen, Hikers, Survivalists. The saw will cut through a 3" diameter limb in less than 10 seconds and it's made of high strength, heat-treated steel, coated for rust resistance. It only weighs 5 oz. and fits in shirt pocket- 28 inches long when uncoiled and sports 124 bi-directional teeth. You can use this thing in two ways: The Darwin Award method (sawing an overhead branch or standing tree, or the Right Way - on felled logs with one foot on the top of the log to apply the proper amount of pressure (light, but positive) with a rhythmic sawing action. The key is to let the tool do the work and not try to "hurry" the process by applying too much muscle. Trust me - it will power through logs on it's own just fine. When you use too much pressure, it tends to bind and doesn't allow the teeth to do the cutting. You can eat a slice of pizza in one bite, but you won't be able to swallow it. Same principle, in a weird sort of way.
