Uh, right, because that's exactly what the OP was asking about.
No question that a Morizumi would be a better tool of choice for cutting and threading a lot of bare spokes quickly. It's a great tool. For the OP's specific job - extending existing threads by a short amount - the Hozan is actually more appropriate. Extending threads by 1 mm or less is easy with the Hozan tool, because it's two full turns of the crank, and there's less concern for damaging the existing threads.
