Thank you for viewing. This is an instructional book and practical video on knife techniques by Tsuneo Tanaka, who was hailed as a master of knives. It has been stored upright on a bookshelf. There is some soiling on the top and bottom of the front of the case (photos 8 and 9). The video tape case has some discoloration (photo 9). The first video tape covers the basics of knives, and the second tape covers how to fillet a sea bream. I believe this is a bible for those aspiring to become Japanese chefs.
