I'm brand new to this website and it seems this is the place to post this. Through the christmas season I took on a house sitting job in payment they gave me kitchen knife from japan. I know from the box that it is a Tsukiji Masamoto but not what type or model it may be. I hope these pictures are good for figureing it out. On a side note theres a little bump on the blade near the tip Im not sure if it's visable on the image. Thanks a bunch for any help you can give me.
