Very interesting. Of course, I would want the best steel possible. As long as my wallet could handle it.
The tatara project makes me want to become an apprentice blacksmith. I wonder if iwasaki will take some new apprentices.Last edited by zenshaver; 08-25-2008 at 11:15 AM.

Thanked: 22There are two Kanji that make up the word Tamahagane, they are 玉 and 鋼 the first kanji there is Tama, which in English has two meanings, ball and jewel. The second Kanji is Hagane, which in English means steel.
A few of my contacts that work with many different tools, say that ball steel is what foreigners call Tamahagane, and a few others have absolutely no idea coz they have never heard of it.
Could my contacts be mistaken? It is possible, not likely, but possible. I have to rely on them, because my knowledge of steels is.... Well I have no knowledge basically.
This is just my 0.02 worth.
EDIT: So the question about ball steel coming from anchor chains, I have to say, someone is pulling your leg. Maybe we need to use that one wish to get our answers.
Here is a link with some info on Tamahagane.Last edited by OLD_SCHOOL; 08-25-2008 at 12:44 PM.

Very interesting link thanks. I got the info from a post at japanesewoodworker forum.( Ref 1st post). As to the truth in it who knows. Tamahagane does look interesting.

Thanked: 150That first post at the Japanese woodworking forum makes a distinction between steel and iron, but it's not as clear as it could be.
Iron, or wrought iron as is usually the case, is mostly pure elemental iron (Fe) with some impurities and slag. It is very soft, malleable, and doesn't harden like steel does.
Steel is iron with a small percentage of carbon added to it. When the carbon levels get up to about .4% or so, the steel can be hardened by heat treatment, with increaseing levels of hardness up to about .7% carbon. Most "high carbon steels" are between .7% and 1.2% carbon.
And FWIW, cast iron is iron with about 2.1% or more carbon added to it. It is very brittle and isn't suitable for cutting tools.
Anchor chains are sought out for use as a backing material by some smiths because wrought iron easier to forge then steel, cheaper to use, and somewhat conventional. The main body of the cutting utensil is made of soft iron, while the cutting edge is a piece of high carbon steel that has been forge welded down the length of the blade.
The reference to iron as tamahagane stems from the process of making the steel in which certain parts of the tamahagane are infused with enough carbon to make excelent cutting tools while some other parts are almost entirely carbon free. The guys in that thread are discussing different types of irons; wrought iron from anchor chains, modern production wrought iron, and iron from the tamahagane making process, not steel in any useful sense of the word.Last edited by Russel Baldridge; 08-25-2008 at 02:57 PM.

Thanked: 5ALso true wrought iron is pretty hard to come by as it has not been seriously manufactured in a long time. But the fibers of slag that are in it produce some useful properties.
Not at all apropraite for a razor, but it can reduce corrosion and when it breaks it breaks something like bread dough and not the sharp cracks you get in even the lowest carbon steels.

IIrc Leon Kapp The Craft of the Japanese Sword translates tama as jewel, and So at japan-tool does as well. I think the best translation of tamahagane is tamahagane. This leaves no doubt what one is speaking of.
I asked Iida-san to check with his wholeseller; neither had heard of anything refered to as ball steel or ball bearing stell being used in anything. He shaves with a western style razor made by Mizuochi-san. When checking to see if any were still available, too bad he didn't ask directly, but he didn't. And sadly they don't make any more western straights.

There are some good online articles discussing the use of nanbantetsu (foreign steel) in traditional swords. It was at the time well received. The utilization of modern steel mixed into the alotment of tamahagane is certainly frowned upon hich is not to say that it doesn't happen.
--
Then there are some tool smiths that have their own special blends made up for them, or have reserves made in their father's time, or use some of the old antique steels imported 50-100 years ago.
I have one tamahagane tool, a kiridashi, that I use now almost exclusively for leather work as I keep on chipping the edge. hopefully it will eventually be sharpened back enough and quit that annoyance. I also have a swedish steel plane made by a smith well known for working in that material and it is really good stuff.

I suppose it is easy to get caught up in the mystery of it all and get something that is more flashy than practical. Especially, if it is from the mysterious orient.I guess I am a sucker for this stuff.I have a kiradashi I have been using for chipping away at the bad spots on my windowframe in my house. I don't think it is tamhagane though. it is welded steel though.I know it is not its intended purpose but it works good.

I remember reading that legendary knifemaker William Scagel used ball bearing steel for some of his blades and googled same. The only thing useful I came up with was this quote from knifemaker Ed Fowler's catalog,"The Ed Fowler Steel My steel of choice is hand forged 52100 steel, the steel of ball bearings. Based upon extensive comparison shop testing and field evaluation I believe that when carefully forged and heat treated, this is the most versatile and dependable steel available to the knife industry.
Be careful how you treat people on your way up, you may meet them again on your way back down.

Thanked: 995I can live with Old School's kanji study. That is also a likely explanation for the source of the ball reference. Occasionally during the smelting process, one finds round balls of steel (usually fairly small, less than 1.0 cm) that turned liquid but did not attach to the forming bloom. These round balls tend to be very good quality steel material from this type of process.
Tool and razor makers will have some access to the tamahagane made for swords. I don't think as regularly as the sword smiths. It's a well regulated material.
