The Slice 10474 Adjustable Slim Pen Cutter adds a new measure of precision to our popular slim pen cutters. With the depth adjustment roller, it's easy to select and maintain a precise cutting depth for any given project. The roller controls how far the blade can extend. Once the cutting depth is set, use the slider as you would any other auto-retractable slider—it will expose the blade only as far as your predetermined length. When the slider is released, the blade automatically springs back into the housing, protecting you while the tool is not in use. As with all other Slice pen cutters, the 10474 comes with an installed 10404 rounded-tip blade and is also compatible with the pointed-tip 10408 blade. Slice blades feature our finger-friendly edge that's safe to the touch. Made from zirconium oxide, Slice blades are non-sparking, maintenance free, and never rust. They last up to 11 times longer than comparable metal blades, which means less handling, more value, and fewer opportunities for injuries.
