The OLFA® DC-5 with belt clip is designed to make life easier, faster and safer for anyone who uses a Snap-Off cutter. To use the snap case, pull down the front flap, insert your snap-off cutter into the slot (with the blunt segment extended) and pull towards you to snap it off and let it fall safely inside. Once the case is full you can pull open the top flap and discard used blades safely, making the case ready to use again.
