Bizento in the Fukuoka Ishido School. Unusually for a 20th century smith, the smith signed with a simple two character mei. It could be Kobayashi Munemitsu whose lineage goes back, via his teacher Uragami Munekage, to the Bizen Yokoyama school. The other possibility is that it is the smith who studied under Sakurai Masatsugu, who was a pupil of Koyama Munestugu.
Whichever Munemitsu it is, there is a wakizashi by the same smith here.
The blade has a very good 'feel' to it, and would probably be an excellent cutter in the right hands, and highly suited for tameshigiri.
