Misono (which I use daily at work) is a great brand. I use Swedish steel, which stains easily, but is a joy to use.
Masamoto is a very good brand, pricey but well worth it. Near perfect geometry (not just words, use one for 8 hours a day and you'll understand).
Hattori I've only heard about, little complaints.
I personally use Konosuke (another competent brand) and misono.
