As we loved our ELUK06 so much, we decided to create the ERUK06, our second generation of heavy duty auto retracting blade that has been designed in house for a stylish and ergonomic feel. Our unique approach to ergonomics has enabled us to use quality materials to create a true ambidextrous design to give you precise and controlled cuts in a truly stylish manner. Due to the blades robust and durable design, we had to make some compromises with regards to blade storage, and removal/installation requiring use of a screwdriver, but the end product is one that we are proud of. Please remember to recycle all plastics and metals appropriately.
