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.
