Patrick Leach's Inner Sanctum
The invention is a cammed adjuster wheel that interacts with a cutter carriage to provide cutter adjustments.

The adjuster wheel looks like a faucet handle. However, the planes get their most distinctive look from the vertical corrugations on the plane sides, and moreso from the sine wave corrugations on the sole. The corrugations are not claimed.
