Equipped with a very attractive koshirae, this tanto is a unique dagger in the Shobu shape.

The sword is in very good condition, with no flaws, chips, or dents of any kind. The itame hada has an active hataraki of yubashiri and chikei with some mokume mixed in. The hamon of Gunome Choji is very dynamic and has hataraki of ashi and sunagashi. The shobu shape of the cut end has a hakikake boshi.

On the nakago, there is a single letter "sa" in gold inlay. Sa was a group of swordsmiths based in Chikuzen Province (present Fukuoka Prefecture) from the end of the Kamakura Period to the beginning of the Nanbokucho Period, and they engraved one character of Saemon Saburo in their inscriptions. The koshirae is a fine kizami style aikuchi and is also equipped with a kozuka knife.

This wonderful long tanto will be sold at a special price unique to Tozando. The early bird gets the worm.
