EdgeKeeper 11cm Self-Sharpening Utility Knife 5 "Good product" Mrs Simmonds 27 July 2017 I bought this knife and the paring knife at the same time. They are excellent with nice sharp blades that I know will not become blunt. My only concern is that the sheath for both knives are the same size and the Utility knife does stick out of the sheath a little and could catch on things. Not sure if it was intended that the sheath would fit both knives or if perhaps it had been packaged incorrectly at the point of manufacture. A note from the team Thank you for your review. The sheaths are the same size and designed to fit all sizes.
