Every woodworker should have one of these in their tool kit.
A thumb plane.
Nothing more than a real small plane with a blade no more than one inch wide.
For being so small, it has a lot of versatility.
I use mine mostly for creating small chamfers, or for easing sharp corners on project components, but it is also a great little tool to grab for trimming veneer edges, cleaning up small dovetailed or box jointed corners, flush trimming dowels, and even finish smoothing work on small parts.
Just don’t let it get lost in the shavings made by its bigger brothers….
