In a Morizumi spokes are cut the way wire is cut in industry. If you want a clean cut, a shear is used. The wire is stuck through a round die. This piece supports the main wire during the cut. 360 degree support.
Across the round die’s ground surface comes a shear blade. Result: a perfect cut with minimum resistance. You can sharpen either part with conventional grinding and sharpening.
Even so, we offer new sets. The 12/13g threading dies come with a new round cutting die. This is so the thicker wire of 12 and 13g spokes will fit into the cutter. Leave this die in place when you switch back to threading 14/15g spokes. It works fine on the thinner wire.
