摘要： A telescoping series of coaxial nested tubes 1-4 extend to provide an elongated handle. Each inner tube of the series has a back end with a gradual conical flare. Each tube that encloses a smaller tube has a front end with a gradual conical reduction. At full extension the tubes stop and bind against each other, so no clamps or screws are needed. A pruning saw blade 7 is attached to the front end of the innermost tube 4. The innermost tube is shorter than the outer tube 1 by at least the length of the saw blade, so that all the tubes and the blade retract within the outer tube. Caps 10 and 13 close the outer tube on each end. A resilient damper in each cap presses against the ends of the inner tubes, preventing motion and noise among them. A spare saw blade can be enclosed in the innermost tube 4. It can be retained in a hole in the back damper 11, or in a resilient slotted plug in the innermost tube. The front cap 13 preferably includes a direction-finding compass 15 for wilderness use. A threaded bolt 14 or other attachment means preferably extends backward from the back cap for mounting the collapsed saw in a convenient location.
