Hi John, I am not an expert and certainly could not date the blade accuratly beyond a certain point, but some dead giveaways as to if it is fake or not or pre world war 2 are in the character of the steel. The mass produced blades in ww2 were monosteel and do not show any evidence of being folded. In chinese blades the folded characteristic is often grossly exagerated and very plain to see. A close up of the blade surface that is in focus and shows detail would be most helpful in determining if its pre ww2 and actually of Japanese manufacture. Other than that I would deffer to the Nihonto experts. They will require good photos aswell, the ones you supplied in this thread dont say much at all, I can't tell if its a foiled habaki or a brass habaki? Can't see if hada is present or not? Based on your dimensions and the butchered looking tang with out markings, it may have been cut down from a longer blade by moving the shoulders up the blade. Then again it could be anything from anywhere at anytime....Helps allot dosn't it :) Need quality photos. |

I know my pics suck.... I'll post some better ones this weekend. I can tell you though that the habaki (blade collar) is brazed copper peices 4 peices to be exact there is a brass color between each peice. The Hada is a straight grain. The hamon line is bairly visible but seems to be a toran hamon (billowing). It has a medium Kissaki (tip) and an ihori type mune (blade shape). There is also a few minor flaws which i will show in the better pics. I do know however from the research that i have done that this blade is folded, the flaws that is has could only be on a folded blade, there is Ware ( "Horizontal "lines" (splits) generally due to a poor weld between layers of steel"), and Shinae ("Ripples or wrinkles in the skin steel generally due to a bent blade having been straightened"). http://www.geocities.com/alchemyst/kizu.htm |

| Congratulations on a fine blade! I am only responding in order to slightly dampen the enthusiasm however. Though it I am no expert and it is certainly a tachi blade and probably not a gunto the attempts to date her by shape concern me. Japan in the eighteenth and nineteenth centuries, that is and pre-meiji, was undergoing a certain fit of nostalgia resulting in the manufacture of weapons and armour of archaic styles. Now personally I would be ecstatic to have any pre-WWII tachi or katana as you almost certainly have but I think its premature to conjecture on exact period. |

| OK I finally have some updated pics, i hope they help. I want to make it clear that i am not staing that i know that this sword is from that time period it just seems to be the shape, size and style from that period.
I hope these pics help. Thanx, John |
