Adam puts a spotlight on one of his favorite shop tools, the Pica pen. While he has hundreds of markers in the cave, this particular marker stands out for having a tiny point that can fit into corners and holes. It's extremely satisfying to use for tracing and marking up projects--you may have seen it in previous One Day Builds!
