Crescent have recently released the ultimate DIY tool, a convenient multi-purpose cutter called SwitchBlade.
The clever tool comes with 4 interchangeable tool heads and can be used
to cut cardboard, plastic, vinyl, sheet metal, rope, wires, cables,
carpet, shingles, and other types of materials. Simply pull out the two
quick-change pins and choose the adequate blade to suit your cutting
needs. The SwitchBlade set comes with a nylon tool pouch that keeps
everything together.
