INTRODUCTION |

The
new blade is a Hira-Zukuri, medium niku, made of 1065 steel, heath treated the
Japanese way, with an extremely hair shaving sharp edge and
800 grit
polish with a visible hamon and a round boshi. |

The
scabbard should be in a nice wood with black
diluted dye and lacquered with a matte finish.
Black leather 2mm none braided cords should further reinforce the epoxyed halves. The
kojiri
should be in African black wood. Aim is to use it to hit the opponent.
There is no habaki, as the koiguchi area should hold the blade well. |

| THE NIKU ISSUE | ||||||||||||||||||
![]() |
||||||||||||||||||
|
This drawing-diagram is made to scale. The niku issue is indeed a very important issue considering that a hira-zukuri 35 mm wide could not be a plain triangle. Therefore I have divided the blade section into A which is perfectly straight, for about 10 mm. Section B is where the niku resides more, showing that for the next 15 mm the blade is gently curving in an elongated ogive. Finally C shows the remaining 10 mm finishing the curve and being straight for a fine cutting edge, reinforced enough. |

THE SOURCE OF INSPIRATION |
||||||||||||||||||
|
This is the antique dha which I studied in terms of functionality. The 11 inches tsuka I have indicated will have very important role not only as a handle but as well as a striking source. Construction should therefore be very strong as well. |

The pictures show the post quench blade which turned a koshi-zori, something that I am fully comfortable with. |

At a later stage Nathan sent a couple of pictures of the hamon. I asked him not to go further as though it is not a Japanese style blade, I have resisted the temptation to further the polish for the time being for it is mainly a working blade. Full polish can take place at a later stage, when the blade is retired. Nonetheless the hamon is very nice. |

The blade looks very good and the hamon is very nice. The round boshi looks beautiful. A discreet hamon with a final polishing compound finish will make the blade have a matte finish. |

Here is where I have asked Nathan to stop, at 800 grit. The blade is fully functional and now the mountings work can begin. Both pictures are of the boshi, taken at different times. |
||||||||||||||||||
|
|

|
I have requested Nathan for a very sharp blade that could shave hair. Run your mouse over the image below. |
||||||||||||||||||
|
|
||||||||||||||||||
|
I am fully aware that this is not an absolute necessity, but the 1075 steel used together with the blade heat treatment and the carefully planned geometry should keep the edge fairly well. |
||||||||||||||||||
|
THE MAKING OF THE FITTINGS |
||||||||||||||||||
|
I chose stainless steel for the fittings which were a bit hard to make, but to my taste, Nathan fully succeeded. And I very much loved his N mark on brass inserted into the steel. |

Here we can see the blade inserted in the solid fuchi with the nice brass touch of the signature. |

|
At this time I am aware that this is becoming a very unique project for Nathan has informed me that he has been admitted to medical school. This will not, nonetheless, stop him from finishing this project. |

I chose color 8 for the tiger maple scabbard. |

||||||||||||||||||
|
Here is an example of the leather chord wrap that will reinforce the scabbard apart from it being epoxyed and lined with thin flannel soaked in mineral oil. This 5 cord wrap could be used for the koiguchi at 1.5 cm from the opening, tightly wrapped. |

|
The tiger maple boards that Nathan ordered. They are thick because the first third of the koiguchi end will be round as a cilinder then changing to a flattened surface. |
||||||||||||||||||
|
|
||||||||||||||||||
|
The blade's shape is been drawn on the board with the oil deposit. |
||||||||||||||||||
|
|
||||||||||||||||||
|
Nathan carving one half of the scabbard. |
||||||||||||||||||
|
|
||||||||||||||||||
|
Then lining was applied with glue. Once dried it will be soaked with mineral oil. The advantage of lining a scabbard is that it avoids scratching, it oils the blade and avoids rattling. |
||||||||||||||||||
|
|
||||||||||||||||||
|
Here
we can see the blade fit in the scabbard half. The handle is yet to be
finished. Nathan is managing his time very wisely. First doing the rough
work. |

The end result as can be
seen in all these pictures is a blade that is nicely blended with the wood
scabbard that renders somehow a kind of subtle yet primitive and
simultaneously refined look, something I cannot describe so well as I can feel.
|
||||||||||||||||||
|
It is also very enriching to
work long distance in a highly communicative way as Nathan and I have
worked. Like all smiths I know, Nathan is modest and humble on his skills,
considering that he made the sword, the fittings and carved the scabbard,
finished it all in four consecutive week ends. |

|
The
sword was received by me on August 19, 2004. It was very carefully packed
in a thick tube. |

The original dha and the new interpretation. I have handled it and everything is very solid. The custom-made scabbard could break some bones with a hit, so as the very solid African Blackwood handle. The blade is thicker in the mune as compared to the antique dha and just by viewing it one can see it is much more powerful. |

|
The scabbard is shown in a position where the swelling allows for a superb grip, and its overall strength in construction can be felt. Nathan understood my request. The sheathed sword becomes in itself a powerful weapon capable of causing severe traumatic damage. Once sheathed it is not easy for the sword to leave the scabbard. A correct pull must be performed. |

The blade, due to its 35 mm width and 4.5 mm thick is like a cleaver and exudes far much more power than a machete. It seems like the hybridation of a machete and an axe. I am not at all concerned with the hybrid polish look. It does match the raw beauty of its fittings and the connection with the powers of nature. |

This
view shows the solidity of the ensemble and how it can become a variation
of a short
suburito .
Although a look on the symmetry achieved by the flaring fuchi
to the entire ensemble, and though some techniques have already been
developed for this sword, its overall built and configuration almost leads
to understanding how the techniques can be performed. |
