How to cut plywood by hand?

1. Measure the piece of plywood you want to cut and mark the area with a pencil.
2. Secure the plywood to a workbench or other stable surface with clamps.
3. Cut along the marked lines using a fine-tooth handsaw. Start at one end of the line and make sure to apply even pressure as you go along.
4. Use sandpaper or a file to smooth any rough edges or inconsistencies left by the saw blade. Sand in the direction of the grain, as this will ensure a smooth finish.
5. If you need to make more precise cuts, use a jigsaw, circle saw, or circular saw for straight edges.
6. To cut curved lines or shapes, use a jigsaw with a fine-toothed blade to avoid splintering the plywood.
7. For the best results, use a wood-specific blade and go slow when cutting. Work patiently until the cut is complete and then use sandpaper or a file to smooth any rough edges.
8. If you’re having difficulty cutting the plywood, you may want to consider using a router with a suitable bit or a hand-held router plane. Both of these tools can help achieve a smoother, more precise cut.
