Always-ready saw guide
I needed to cut a small piece of bendable plywood to final length for my project, but the piece was too unwieldy and fragile to cut safely with power tools. I pulled into service a traditional woodworker's tool—a handscrew—to act as a guide for my handsaw.
Line one side of the handscrew with masking tape to keep the saw teeth from damaging the clamp. Clamp the handscrew to the workpiece while holding the saw against it to align the saw on the cut line. Then clamp the handscrew in your vise to make the cut, guiding the saw flat against the jaw. This technique works so well I've started using it on other projects that require small workpieces.
