Hello I am new to the forum and a beginning collector but lived in Japan as a kid and a long time practitioner of Kendo so very interested in swords. I saw a tanto in a store the other day on consignment. The owner of the shop had it advertised as a WW2 suicide knife. The pin holding the tsuba looks like Bakelite to me, any help identifying what it is and its approximate age would be really helpful, I am trying to decide if I should buy it. Thanks so much!
