## Summary

Luke Lyu, founder of Zen Wu Toolworks, explains how his company combines traditional Chinese plane design with modern CNC and EDM manufacturing to create high-performance hand tools. He details the engineering challenges of optimizing hammer harmonics and plane blade preload, noting that standard FEA software fails to capture the tactile feedback required for good tool feel. Lyu also describes the Zen Sharp sharpening system, which uses magnetic spring steel cards to offer an affordable, accessible alternative to traditional stones, reflecting his philosophy of balancing premium quality with accessibility.
