This document discusses holding devices used in carpentry and joinery. It defines holding devices as tools that grip or hold items together, listing examples like vices, G-clamps, F-clamps, sash clamps, hold fasts, pliers and pincers. The document notes that clamps can damage wood by applying too much pressure, so scrap wood is often used between clamps and projects. It also provides brief descriptions of G-clamps, F-clamps, and sash clamps, and recommends storing G-clamps horizontally and sash clamps vertically. The overall aim is to introduce learners to common holding devices and their uses.
