As you can see I am new here, I have been trying to study the ins and outs of Japanese swords. I have always wanted a representative sample or an original WW2 Japanese edged weapon and have found one I need advice on,eBay item number: 310748792272 , I have talked to the folks selling it and they claim they have had two experts confirm it is authentic, strange thing is they have 2 more different style Japanese swords for sale and they all appear to be in too good condition. Would it be asking too much for you to look at the item number and give me your opinion?
