Our Story
After years of using rod guided hone systems one problem always persisted. The tip and heel of the blade ALWAYS had a shallower angle. It's simple geometry. The angle changes the further away from center you are. In fact, it could be as much as 5 degrees off on a standard kitchen knife! So, we solved the problem by creating a very slight parabolic curve in the rod guide. This minimizes angle variation from the center of the blade to the tip and heel. Elegantly simple. Sure Angle will craft the perfect edge with a precise angle, every time.
Investing in a great knife is something we can appreciate. We can keep those edges sharp and consistent whether it is your EDC folder or a high end chef's set.
