The Forest Ninja

I purchased a set of five Bo Shuriken from Japan in the style that the Tenshin Shōden Katori Shintō-Ryū used. Bo Shuriken are throwing spikes that are legal in Canada.

A couple drops of acetone would clean better than alcohol.

One issue that be that may present itself is most Katanas were forged using Kobuse style with a softer steel sandwiched in between harder steel. So using a broken or older blade to forge a new Katana if it's folded again would mix those two types of steel together. If You're only going to be forging a knife or tanto it would be a non issue though.

Leave the Ninjas alone. Name 1 who caught caught doing a crime in UK. Most of all blade crimes are with kitchen knives. So go after Chefs instead.

Maybe, the website meant Yen vs USD? 100,000,000 Yen = $66,167.804 US Dollars.

People do spend lots of money on items that others may find crazy at times. But if they can afford it so be it.

Tempering can results in crack(s) if it not done immediately after a quench in some cases. But it should have been caught before the blade was put for sale.

Checking the blade after a quench for issues is what normally happens. The Swordsmith should have caught this before the blade was sold.

I got myself a Starfrit Digital Kitchen Scale, 5-kg. Accuracy: 0.1 oz / 1 g Here's a YouTube video about it.

I think even large Fries are bigger in North America.

I got a few books, but they're in Japanese. Need to translate them. I'm waiting for warmer weather to light up my charcoal forges so I can finally start forge welding my Tamagahane piece into a blade. Also hoping my Hamon skills improve. I've tried 3 quenches and only the last one had some Hamon showing here and there. It's a fine art of proper clay application and good temperature to get it right. I'm gonna try a lot more quenching this year.

Every once in a while I'll flush My DNS and more using commant prompt with My Windows PC https://runcloud.io/blog/flush-dns-cache

I'm a new person here and already want to put somebody's bazillion new Tamahagane threads into one. Brian, I hope You get a new MOD in every continent so there's basically somebody around all the time. I still need to learn the parts of a Katana before I can upgrade. Cheers

I've had the same issue purchasing some Japanese Whetstones. Contact them and tell the books are not banned. 90% of the time I contacted them They unblocked the sale. Also, do check the Mercari section of Buyee. I've got a few books from that store.

I'm not sure how many of You know this, but the Tatara is broken up and metal sorted. The pieces with low carbon can be reused to add more carbon in a reducing environment. The pieces with too much carbon (aka cast iron) can be reused in an oxidizing environment to reduce its carbon content. The pieces that are good from the intial run are used as is.

Btw: Electrolytic iron is not a new invention. So You can forget about getting a patent on it. Read more about it here. Electrolytic iron

I don't know of 1 blade that was ever created by using electricity alone? Do You have a link for this Mustafa? I do have pure Electrolytic iron and pure iron powder which can be used after it's carburized to make a blade including a Katana. But that's totally different than what You're thinking about I suspect. Note: I think it would better to have all Your steel threads put into 1 thread so it's easier to answer and keep everything together.

Never heard of Manu. I think You meant Maru. Kobuse is more commonly used these days in either a Katana or Wakizashi. A Tanto can be Maru cause they are not exposed to the same stress as a sword. From here: Japanese swordsmithing

I got mine from here. But they're sold out now. TAKEFU SHIROGAMI #1

It wasn't cheap and I only used a bit to make a knife. Still got 2 feet left sealed and oiled away for a later project.

I have purchased a bar of Shirogami #1 (1000mm long X 40mm wide and 6mm thick).

It twould better to create only 1 thread regarding steel so that all the information ends up together.

Doubt You find that entire book translated. I do have that razor shaving pdf file though.

I got a Japanese book called "How to View the Blade" by Kosuke Iwasaki" that I need to get translated. Here's the book description after it was translated. Will take way more time to translate the book though. Kousuke Iwasaki (b. 1903, d. 1967) was more than just a maker of razors; he held a PhD in metallurgy from Tokyo University, he was apprenticed to swordsmiths and barbers, and his book "Regarding Blades," ｢刃物の見方｣ is still considered one of the leading works on Japanese smithing, metallurgy and Tamahagane ever written. He was born into a family of blademakers, but his father’s business was destroyed by the enormous influx of cheap, mass-produced yet still highquality German cutlery after the first world war, and he swore to establish Japanese blades as the best in the world as revenge for his father’s losses. This mission led him to studying the ancient secrets of the Japanese bladesmiths, as well as his lifelong research into Tamahagane and swordsmithing. He eventually transferred his focus to razor making, both of the traditional Japanese Kamisori as well as western-style straight razors. Sanjo's blacksmith has a microscope. Based on the conviction that knife making should be backed by science, the author, who has mastered swordsmithing and sword sharpening, teaches the actual relationship between tamahagane and other knife materials, blades and sharpening, and whetstones. A wide range of topics linking technology and metallurgical theory are explained in detail. Fantastic masterpiece reprint. Release date: May 2012 Author/Editor: Kosuke Iwasaki Publisher: Keiyusha Form of issue: Paperback Number of pages: 177p

Shelter would be nice. But I was knife heat treating in the dark. It's nice seeing steel turn a light lemon yellow the 1st time. I got a crucible forge as well that I'm going to use to make custom steel.
