Does your FIRE ring have flat inside edges or curved?Updated a year ago
Curved. The inside edge of our FIRE rings is cut on a radius. Skate steel is very rarely perfectly straight, and with a flat inside edge you will very quickly lose the ability to sharpen the section of bent steel. The radius inside edge of our FIRE rings makes them more forgiving than a traditional FBV because the radius inside edge is able to compensate for bent steel. You will get a better, more consistent sharpening with a radius inside radius edge.
