Safely Cut Wood Over a Wire using a Chisel

What happens here

With the wood positioned over the simulated electrical wire, select a sharp chisel and a hammer. Place the cutting edge of the chisel perpendicular to the wood grain, directly above the wire. Carefully and gently tap the chisel with the hammer. Apply controlled force to cut through the wood, ensuring the chisel does not penetrate too deeply to avoid hitting the underlying wire. Repeat the tapping until the wood piece breaks cleanly, revealing the undamaged wire beneath.

Goal: Cut through wood precisely above an electrical wire without causing damage.
