Work Sharp Precision Adjust Stability Cube — SFS Upgrade

Fix the Precision Adjust Wobble — Instantly.

No tools, no mods — just drop it in place and the wobble is gone.

🟠 The system wobbles when pressure is applied.

 

This causes inconsistent bevels, unstable angles, and frustrating sharpening sessions.
