Replaceable-blade precision cutters include any type of precision cutting tool that allows you to replace the blade. The Slice Craft Knife is one example of this style of tool (also available as the 10589 with Never-Lost Safety Cap). This kind of cutter works best for materials that are too thick for a fixed micro-ceramic blade. Other Slice knives in this category include the Precision Knife and the 10568 Scalpel.When the blade eventually dulls on a replaceable-blade knife, you can keep using the handle by putting in a fresh blade. Slice craft knife blades, which fit most of the replaceable-blade tools mentioned here, come in several styles: rounded-tip, pointed-tip, concave seam rippers, double-edged, and chisel blades. This allows you to customize the same handle to fit many needs. Applications that require a piercing action are better suited to pointed tips, while rounded tips add a level of safety to precision knives, guarding against accidental punctures.
