According to the online shop where we found these, the Lowe-Scheren miter cutter is “similar to a garden shear,” but a “built-in fence allows you to cut miter joints quickly, easily, and with accuracy.”
They’re handy if you’re looking to do some home picture framing or if you need to cut miters in small moldings often. The fence makes 45-degree cuts easy, and the base has markings for 15, 30, and 90-degree cuts as well.
They’re also a bit pricey at $45.95, but we have yet to find a set available elsewhere. (If you’ve come across a less costly set, please let us know.)
