You can always use an extra vise around the shop. A light-duty vise from Lee Valley is an easy, inexpensive addition. The vise just clamps to the edge of the worksurface when you need an extra hand.
The large, wide drawers of a tool cabinet can get cluttered, so I bought Inexpensive bins from Akro-Mils. They fit inside the drawers to easily contain smaller tools and hardware. To keep the bins from sliding around, I cut strips of 1⁄4” hardboard to fit inside the drawers and attached them with double-sided tape.
