I have forged tanto from tamahagane and many hunting and kitchen knives. I have made and worked regular damascus on hundreds of knives and swords. The tamahagane I used previously was already reduced from the bloom to a basic billet when I started the projects. I am a skilled bladesmith and am well known in the knife community. I am the moderator of Shop Talk on Bladeforums. My user name is Stacy E. Apelt - Bladesmith if you want to ;look up some of my projects and experience.
I have participated in making tamahagane at the Ashokan Seminar in the USA several times. Next year will be a "sword year", and we will do a tartara melt, reduce the bloom, and forge a sword in three days.
アメリカでのアショーカンセミナーで玉鋼の鍛造に参加していました。来年は刀の年になるでしょう。私達はたたら製鉄を行い、ブルームを還元し、三日以内に刀を鍛造するでしょう。
私は米国にてアッショーカーンセミナーで玉鋼の製作に携わったことがあります。来年は「刀年」となり、三日間でタタラ溶解をし、ブルームを精錬して刀を鍛造する予定です。
Kevin Cashen and Rick Furrer are world renown experts on making such steel and they supervise these melts and sword production.As to this lot, I understood that it would be a slice of the bloom, and thus would need reducing under the hammer to a solid and workable block before folding to consolidate the steel and evenly distribute the carbon content. I had figured about ten folds would be required. Once reduced to the final billet, I would cut the bar into five pieces and stack for another set of welds. The final billet would be reduced to attain the desired hada. I expected this material to be of the same quality shown in your eBay sales . This one shows that the metal is solid and reasonably compact:
このロットはどうかと言えば、私は以下を理解した。光沢のスライスになるのは、鋼鉄を強くするため折り曲げる前に
ハンマーを受けて固体で加工できるブロックに変形する必要がありカーボン含有量を配分する。また私はおよそ10回の
折り曲げが必要であると考えた。一度最後の鋼塊に変形されると、棒を五つのピースと溶接点のもう一つセット用
スタックに切り分ける。最後の鋼塊は望む肌を獲得するために変形されます。私はこの材料があなたのeBay販売で示されよう
に同じ品質であることを期待していた。この材料は硬質な金属で相応にコンパクトに見える。
10フォールドは必要とされることがわかりました。
最終鋼片は要求されてるハダに達成するために減少されるでしょう。イーベイセールで記載されているものと同じ品質であることを期待しています。
こちらはこのメタルは固形でとてもコンパクトです。
The material you sent is mainly slag, with pockets of steel along the cut edges and in small chunks toward the outside. It appears that this was the waste cuts when the solid material was removed from the core of the bloom. To use this, I will have to work it down and break out all the actual metal, bind the lumps together, and forge weld them down to a solid mass.
I will send more information in a second reply, as the number of characters available for this reply are exceeded.Here is the material you had online that was much better than what I received:What I really would like are two to five reasonably solid blocks of tamahagane steel, preferably cut from the interior of the bloom.
次の返信で更に情報を送付します。なぜならこの返信への文字数が超過しているからです。こちらが、オンラインであなたが持っていた素材で、私が受領したものよりずっといい素材です。私が本当に欲しいのは、二つから五つほどの、できればブルームの内部から切り取ったかなり固い塊です。
I would gladly pay the return shipping for this material and pay the shipping for the new material if it would be better quality. I would like photos of any material offered. As I said in the first part of this reply, the material shown in the linked sale was much higher grade than what I received. The need for the 1000 gram lot to be in two pieces is not as important as having good quality. It could be in 200 gram pieces if needed. That may actually be easier in reducing and consolidating the tamahagane. I can stack and weld them together in working the final billet.
