Two tools in one handle, for the two jobs that come up constantly once a kit is out of the box: a shovel-shaped scraper blade at one end to shave seam lines and clean up flash, and a tapered reamer at the other to open and true holes.
The scraper end is ground flat with a chisel edge, so it rides along the surface and lifts a controlled shaving instead of digging in. The reamer end enlarges a molded hole a fraction at a time, which lets you seat a detail part without cracking the surrounding plastic.
Opening a hole with an oversized drill bit tears the plastic and leaves a ragged lip. A hand reamer cuts on the taper and leaves a clean round edge, and having it on the back of the scraper means one tool stays in your hand for both steps.
