We're going to post some one-off pieces that Mark is grinding from some old standard patterns. They're posting as they finish.

We will get back to our regular scheduled Friday sales in a few weeks. I apologize for the inconvenience.

lol i have no chance at this unless its possible to get a proxy . the refreshing is going to be interesting.
 
Our next sale will be 10 ninja swords

We have about 30 swords remaining from a heat batch that was exposed to oxygen at the wrong part of the process that resulted in some surface decarburization

At temperature, carbon flows through the iron metallic crystalline matrix like water in sand. It's not actually reacting with the iron atoms. The mechanism that makes steel hard is literally just carbon getting trapped between the iron atoms that make up the metallic crystals. At temperature the iron is a face center cubic crystal and at room temperature it is body center. At high temperature the carbon flows between these atoms while they're spread out and physically gets stuck as they try to move back, causing strain. This is the mechanism that makes steel hard. Other mechanisms like crystalline dislocations caused by precipitation make other metals hard, and there is some of that in steel, but by in large it is martensite.

However, at the high temperatures that this steel is processed at, if there is oxygen present that carbon simply combines with the oxygen to make CO2 gas. They are specific steps in the heat treat process where the steel is at very high temperature and is highly susceptible to decarburization. Due to the challenges presented in processing this steel in a sword, we ran into some difficulties with one heat which resulted in decarburization of 32 swords.

Historically, a wakizashi sword might be hard in the middle and clad with soft steel, so, ironically, this flaw makes the sword more period correct. But it also makes it easier to take a set because the skin has a lower yield point than the core.

We are auto grinding the flats to remove the decarb, and setting the edge back to remove suspect steel from near the edge and we are working on some techniques to reprocess the primary grinds to at least reduce the presence of the affected steel

It looks like we have enough good swords to fill the pre-order, with a couple left over. However I am not selling any of those until the pre-order is complete. However we have 30 of these that I'm going to reprocess into a ninja sword and offer for sale in batches of 10.

Our next sale is for 10 "ninja swords" wakizashi. These are in process now. I will firm up a date once I have a better feel for when they're going to be ready.
 
We are hard at work on the K20 and Shiv pre-order. We will be releasing onesie twosies that Mark is working on to stay busy as they are finishing up. Once the K20 is out of the shop, we will resume normal Friday sales.
