This is a piece I have been wanting to make for a long time. Not too fancy, just simple and straight forward.

The wearing of Uchigatana somewhat predate the widespread use of daitio (katana and wakizashi worn together) as it is a more practicalblade for everyday than was a tachi. Aikuchi simply means guardless, as many uchigatana were mounted. The primary difference from a katana is generally length and usually in more simple mounts.

This blade is forged from W-1, traditional clay heat treated, water quenched. The nagasa is 26 1/4", in shinogi zukuri shape with chu kissaki. The sori is shallow tori-sori and the hamon is hitatsura, or "all over" pattern. I have really enjoyed this hamon style, and am leaning towards specializing in it for all of my Japanese style blades. It makes a very good blade for performance, and is very stiff ( no deflection in a blown cut). These blades always warp a little during heat treatment, and it was a bear to straighten. It put over 30 degrees bend to it before it would stay straight for me. It also has so much activity, I see something new every time I look it over.

The blade is very wieldy, and quick. It feels better than most wakizashi I have handled. It cuts very well too. 1" saplings were no problem.

The finish is hybrid. Hand sanded to 2000, lightly etched and finished with traditional finger stones and nugui. The finder staones leave a more authentic look, and don't tend to leave the blade so bright.

The mounts are bass wood, simple copper fittings and finished off with base/clear automotive paint ( MUCH easier and available than laquer, tougher as well). The tsuka is traditionaly made with silk ito over same in katatemaki style. The kashira is a piece of fossil ivory with a redish color, to go with the heat colored copper fittings and saya color. The menuki are small fish. I hadn't installed the mekugi at the time I shot the pics, but it is in there now.

Hope you enjoy the pics, if anyone is interested, contact me off forums.

Let me know what you think!!

Very nice Bailey! The aikuchi mounts are not to my personal tastes, but nicely done nonetheless. I liked the use of ivory for the kashira, as opposed to horn.

I can see why you're leaning towards doing more hitatsura hamons - you get some great results with them. I actually picked up one of your previous hitatsura efforts recently and was very happy with the purchase. Nicely done all the way around.
 
Strikes my chords. Well done. One question.

Any worry about the break in the hamon in picture #4? Not that it isn't strong without the differential heat treat but would you be concerned with force coming into contact with that area and if not why?

Love it. Great job.
 
Simply beautiful. That has to be one of the all-time cool hamons as well.

Ok, where's that bowing, "We're not worthy" icon, when you need it? :)

Awesome, Bailey; Simply awesome. :thumbup:
 
Thanks for the compliments, I get a lot of satisfaction in making Japanese style pieces.

Jeremy,...which piece did you get??

G3...I am not concerned with the area you indicated from the picture. I did draw the spine back to a springy temper, and put a pretty good amount of stress on the blade in testing. Modern tool steels don't necessarily need to adhere to the same rules of thumb that tamahagane does. While modern steels don't exhibit the same artistic qualities, they certainly are superior in performance, consistency and predictability in process. So, my testing of the blade and the amount of force I had to apply to straighten the blade gives me total confidence it the blades integrity.

Just for comparison, the wakizashi in the pic has a similar effect.

Thor,....does this one look familair ;)

It's a kat I picked up from Mike in Chicago - don't have any pics of it right now - wrapped in blue with copper furniture. Really a nice piece, glad I picked it up before someone else did.

hi Jeremy...i'm glad you like the Kat. it was sure painful to let go. i was trying to acquire another Bradshaw kat-Fall Splendor. ALAS! someone beat me to it.

btw, did you get your keys for your case...i never heard from you. now i only have 3 katanas left. :(
 
Very nice work Bailey. The hitatsura hamon is beautiful. I always wondered how it affect cutting and durability as it seems that it would stiffen the blade along the mune.
