RECA ultra safety cutter with fully automatic blade retraction for maximum safety. The blade automatically retracts into the housing as soon as it loses contact with the material, even if the feed mechanism is still held in the forward position. A locking mechanism prevents the blade from being pushed out accidentally. Easy blade change — no need for tools. Can also be used for cutting films or tapes. Replacement blades are stored in the housing. The ergonomic design means that the knife can be used by right or left-handed people.
