You can make 1/2"-deep precise cuts into foam and paper with the 10589 Craft Knife with Safety Cap from Slice The zirconium oxide ceramic blade has a finger-friendly edge that is sharp for materials, but resistant to cutting skin. The handle's grip is textured, so it will not slip from your hand. The integrated safety cap slides to the back of the handle and with a twist locks into place; therefore the cap is never lost.
The blades are non-conductive, non-magnetic, non-sparking, and chemically inert, so the blade will never rust. Left- or right-handed users can easily use the knife because of its ambidextrous design, and it is compatible with the 10518, 10519, 10520, 10532, 10534, 10535, 10536, and 10537 blades. No tools are required for changing the blade.
