Sport, Military and Collectible Knives | Coltelleria Collini

The 630 and 631 PULSE models designed by Igor Bortolussi are EDC folding knives that are “siblings,” sharing a common design vision but distinguished by the profile of the blade: curved for the 630, Tanto-inspired for the 631. The design, created in collaboration with Straightline EDC, combines soft lines and bold features in a modern, ergonomic, and essential synthesis.

The name PULSE—which evokes momentum and heartbeat—perfectly expresses the dynamic sensation you feel when holding these tools. Both models are equipped with the innovative W-Lock opening system, which ensures greater safety during use.
