The OLFA XA-1 benefits from X-DESIGN excellence. This means that it has a very comfortable, anti-slip grip, allowing you to use maximum pressure to cut, safely. The elastomeric grip takes a lot of the pressure off your hand, resulting in greatly reduced strain over long periods of use. The body is also re-inforced with fibreglass, for ultimate durability and resistance to everyday materials and solvents. The XA-1 has an auto-lock to keep the blade in place during use, and a built-in pocket clip and blade snapper. Pre-loaded with an Excel Black ultra sharp blade.
