Trim Excess Shims

What happens here

After the baseboard is securely nailed, the man uses a Milwaukee Fastback utility knife to trim any excess portions of the wooden shims that protrude from beneath or alongside the baseboard. He carefully positions the sharp blade flush against the baseboard or wall surface, scores the shim multiple times, and then snaps off the excess material. This action creates a clean, flush surface ready for subsequent finishing steps.

Goal: Remove all protruding shim material for a smooth, even surface.
