Which tool creates matching slots in adjacent faces for biscuit joinery?

• A. Plunge Router
• B. Claw Hammer
• C. Biscuit Jointer
• D. Pneumatic Nipper

Answer: (C)

Biscuit joinery relies on precise, matching slots cut into adjacent faces so a biscuit can fit into both and help align and strengthen the joint. A biscuit joiner is the tool designed for this job; it rides along a fence and uses a specialized cutter to make shallow, oval slots in each board at the exact same position and depth. When you apply glue and slide the boards together with a biscuit in place, the biscuit swells a bit as it absorbs moisture, pulling the pieces tight and keeping them flush and aligned during clamping and drying. This approach provides a strong joint with good alignment, especially for edge-to-edge or panel joins. The other tools don’t perform this slotting task: a plunge router can cut grooves but isn’t tuned for the precise biscuit slots; a claw hammer drives nails; a pneumatic nipper cuts or removes nails/staples.
