Want perfect miters in applications where precision really matters, like making picture frames? This miter trimmer uses high-carbon steel blades that are razor sharp to shave fractions of an inch from miters, leaving a cut that some might call glass-smooth.
Since you can’t actually use the trimmer to make miters, you first need to make a rough miter cut with a miter box. Then with the miter trimmer you can shave the piece for the perfect fit. The trimmer is made from cast iron, so it weighs 35 lbs. It has angle presets at 90° and 45°.
We’re not sure who actually makes this trimmer. Rockler, Dieter Schmid, Grizzly, Highland Woodworking, and other companies sell what looks to be the identical tool for anywhere from $150 to $200.
