This Gyokucho retractable blade pocket saw is portable pocket saw with needle-like teeth. It can saw through bamboo, plywood, plastic, 1” lumber and branches. The saw fits easily into a pocket and comes with replaceable blades. It has a locking knob for precise length adjustment. The handle can also be loaded with 3/4 inch Tajima-style box cutter blades. I think this looks like a "put it in the glove compartment in case I see something begging for me to take a cutting". Personally, I think every gardener should have a trowel, a pruner and a little saw at all times. From Japan.
