Phil Wood, Morizum and Kowa all do the same thing:

1. Cut
2. Conform softer steel to the profile of two harder opposing steel elements via roll under increasing pressure.

The Phil handle is arranged such that both actions are carried out in one movement.

The others are two separate operations.

The Phil is horizontally configured making it more prone to debris buildup. The others are vertical. The Phil and Morizumi are made of the highest grade steels and overbuilt making them ideal in a multi-user multi-personality enviroment.

The Kowa is made of the minimum grades of steel necessary to do the job - built accordingly - better in a single-user single-personality environment - and a thousand bucks cheaper.

Early Phil's like FBinNY's allow for 13-16mm threading for old school 16-25mm nipples - when rolled manually. New ones have done away with this ability. Far as I know, the Morizumi cannot do this. The Kowa can do 13.2mm by flipping the spoke-end stop.

As to micro-threading - big deal. If you want micro-threading on Phil Wood - a little more or less pressure on the upper slide guide with the thumb when setting the dies gets it done. Another old trick it to loosen the upper slide screws - stick a business card between the slide and bearing above - tighten the screws - set the dies. (Your mileage will vary...)
