The Zutter Kutter is a heavy duty cutter - it can handle chipboard, bookboard, foam board, Zutter Clipboard Wood, and Canvas and stacks of cardstock. The blades are double sided and can handle hundreds of cuts. When you "replace" your blade the first time, you are actually just turning it around. Each replacement blade is actually two blades.
