I have a couple of Frosts Mora Clippers in both carbon steel and stainless. I really like them. What does this new model offer over the Clipper to justify it's higher price (3.5x the Clipper)? The blade is longer (not a benefit for everyday use) and the grind of the blade is rather unusual. I wonder how fragile the tip is with that strange grind? How easy is this grind to shapen correctly?
