These little gems are, as you might have guessed, small rabbet planes. They are similar in size to Luthier's finger planes (5/16" wide, 1-3/4" long sole and 3" overall length including handle), but with open sides allowing the blade to cut the full width of the sole. You can plane flush against adjacent surfaces while the removable handle keeps your fingers from getting pinched. Bunny planes excel at blending uncooperative mouldings, carving restoration work into alignment, and paring down joints.
The flat sole plane comes with a straight blade to smooth flat surfaces and fair outside curves. It has an optional set of six blades which includes an additional straight blade and five radius blades for work on large coves: 1", 1-1/4", 1-1/2", 1-3/4" and 2". The round sole plane comes with a 3/4" radius sole and blade. An optional set of five radius blades for work on small coves includes a 1/4", 7/16", 1/2" and 5/8" plus an extra 3/4" radius blade.
