Type: Surform Round Rasp
Price: 14.00

The Surform Round Rasp is the definitive industry-standard tool for carving out clean, symmetrical "V" cuts in fish and swallow-tail designs. Unlike traditional wood rasps that can be too aggressive, this specialized tool features a unique "surfers cutting pattern" on its rounded steel blades, ensuring it slices through both foam and wood stringers without tearing or "chunking" the delicate blank.

With an 8.25" blade length and a slim 0.625" diameter, this tool provides the reach and maneuverability needed to navigate deep tail cuts and internal radii. The cylindrical design allows you to roll the rasp as you cut, giving you unparalleled control over the transition from the deck to the tail block. Whether you are shaping a classic twin-fin keel or a modern performance swallow, this rasp delivers the professional finish required before you reach for the sanding screens.
