Cut Door Jamb with Oscillating Multi-Tool

What happens here

With the flooring scrap in place as a guide, use an oscillating multi-tool fitted with a wood-cutting blade. Rest the base of the oscillating tool directly on top of the scrap flooring piece and carefully cut through the door jamb. Make sure to cut across the entire width of the jamb, maintaining steady pressure to ensure a clean, level cut. The scrap piece will prevent the tool from cutting too low.

Goal: Precisely cut the door jamb to fit the new flooring.
