Here is a new build to follow along with. It will take a while before the project is complete because these are being worked on as time allows between orders.

The profile is based upon a blade made in the 1500s with the tang signature "Bizen no kuni ju Osafune Katsumitsu saku". The original blade was made in the Moroha style which is a double edged dagger style. I decided to use the profile but wanted to make the blade in the Yoroi-Doshi style. The Yoroi-Doshi style appeared in the 1400s and was made for close combat grappling and armor piercing. As it was an armour piercing knife the spines were thick, up to 0.39". I went with 0.300" material

One of the things I found interesting is that Yoroi-Doshi were worn inside the belt on the back or right side for left hand draw. I am curious how this design will work with an IWB leather sheath making it more practical to carry. I lean towards leather over a wooden saya because I can make it much thinner which would be more comfortable. Maybe with some nickle silver at the tip and throat to grip the habaki so it draws like a saya. I figure if it turns out to be stupid idea I can always revert to wooden saya. Depending on how the first one finishes I may repeat it or do the second more traditional.

I decided to go with Magnacut for both. One is still available so if you are interested let me know. If they have a home before they are finished you can participate and customize a bit.

Here is the current state and progression.

Made some good progress on the first blade.

Decided to try timascus for the first time. The top spacer and guard are two different timascus patterns.

I went with a filworked copper frame handle that was bedded with colodial silica and epoxy. I really like this construction method. I think the next sword will have it.

Just need to fit the guard and make the sheath. The pics with the handle on do not have the guard in place yet

The first one is ready for the sheath. The balance is about as good as I can get it, right at the guard. Weight is 12.32 ounces and the blade is 9 5/8" to the base of the habaki.

The guard and top spacer are timascus the bottom spacer, habaki and frame are copper. It is still a takedown construction using a pin even though it is frame handle and not traditional.
