The Inland "Wizard" grinder performed magic for stained glass crafters when it was fist introduced almost thirty years ago. The Wizard, and the other new stained glass diamond grinders, made the then time consuming task of smoothing out, and shaping, the edges of patterned glass easy. It sill does today and Inland's Wizard 4 (2002), a distant "cousin" of the original Wizard (1978) grinder is one of the best grinders available. It's also the grinder we use ourselves.
All of Inland's grinder's come with a five year warranty.
