Last year I ran across a planer by Makita I believe, that has a fixed blade and the wood runs under it. I think they are still available in Japan, but the US market is gone. You have to keep the knife very sharp or performance suffers.
Basically it is a 12" or so powered stationary hand plane. Looks just like a regular planer for the most part.
For the life of me I can't find one and would like more info and possibly get one.
Anyone familiar with these and how they perform on diff types of wood?
