I don't often have enough footage to follow right on through, but this project gets close...there are a couple of exceptions, the main one being the blade forging which is actually footage of the sister blade, forged around the same time from the other half of the same spring, to a similar kata...others will be noted as i proceed...enjoy 100-some hours in 22 minutes!

This style of koshirae is a first for me. Though there are examples of several variations right up through Edo and beyond, the lines on this one are inspired by a muromachi piece, the clean, austere "boldness with restraint" makes me think of a gentleman's tanto. Normally I would want to add a very slight bit of embellishment on the saya, but because of its next stop I left it unadorned for now.

The blade is forged from a reclaimed horse-drawn carriage spring made from century-old shear steel. Materials for the koshirae include copper bus bar for the habaki, driftwood Nootka Cypress with natural urushi lacquer finish for the tsuka and saya, reclaimed Congolese silver jewelery for the mekugi pin, and local Oceanspray ironwood for the ki-fuchi, koiguchi, and kurikata accents.

Blade Overview

Probably my favorite piece I have seen of yours. So elegant.
 
thank you, all! here's one of the blade, i haven't any without all the reflections yet, but it shows the"kimono fold" double mizukage, suguha hamon with small turnback, and lots of blistery shear steel hada revealed by a hot water and vinegar etch (not something i normally do, but for this project it is all about the texture)...pictured with Nootka Cypress tsunagi and ki-habaki "placeholders"...

It simplicity is stunning.

It is a pleasure to see it.

Thank you.
 
Great stuff. Love the footage and the end result. Fantastic! Thanks for showing.
Cheers Keith
 
I guess it just comes down to pure elegant simplicity in all your work Keith.

It looks sooooo simple. I am captivated by this piece.

...and a follow-up, this is the mounted sister blade (the one forged in the video above...) the texture in the urushi lacquer finish comes from the crushed iron oxide left in reacted/used up kairo (japanese hand warmer packets)...the urushi reacts with the iron oxide to turn it from red-brown to black… islandblacksmith.ca/2015/03/kuromatsu-aikuchi-tanto/
