The more I see people working with bloom the more respect I have for them and for the difficulty of turning that ugly mass into usable steel. Thanks for sharing your process.
The fact that this technique was developed hundreds of years ago with limited knowledge of metallurgy based on modern science is simply incredible
Hence why Japanese steel and swords had so many impurities compared to European ones
@@anr1593 In fact, katana has far fewer impurities and an overwhelmingly high hrc compared to European swords of the same era.
@@anr1593They both folded their steel.
Id surmise people were much more advanced than were being let on...
Thanks for the information Walter. I really appreciate the knowledge you are willing to share will all of us that enjoy watching whether it be hobbyists, or professionals, or folks who are just curious about the craft.
thanks for a forging vid! not that we dont enjoy the cnc intensive episodes but great to have some hammering action!
The way you explain everything is always fantastic
Cant like this enough. Looking forward to the rest of this series
Looking forward to see our next episode.
I really appreciate people keeping the tradition of how it's originally done alive but in this day and age steel is so so superior making the original process defunct. But its really important for people to see this and give themselves an understanding of where we came from to where we are now. You know knowing what I know now it scares me to think how many blades must have failed in action back in the day. It must have been a real concern for warriors all around the world. Scary
Walter, been enjoying you videos for years, decided to comment on this one. : ) Anyway, learned a lot about how 'bad' welds work themselves out over the folding process. Actually learned a whole lot about the entire process. Always wondered how the smiths got all the welds on that bloom steel perfect the first go, and come to find out, they don't. Thanks for making so many educational videos over the years, I for one, really appreciate it!
The Japanese stuff is definitely your jam.
Good stuff👍🏻
A Walter Sorrell video can never run too long
Great video Sir thanks for your time.
Great work Mr Sorrells!
This is very good info, thank you Walter please keep it coming
Never ceases to amaze me how you turn that moon rock looking stuff into good steel. Looking forward to the next installment :)
Looking forward to it.
Nothing like watching Walter redefine 1000 years of tradition . Way to go Walter Mitty ! Such a abbreviation of a tradition Walter has no understanding of ........ ABS smiths and there arogance !
amazing and interesting videos Walter
Iron sand scratch recipe - part one is is building the foundation. Awesome.
This Is mind boggling for so many reasons. Including the fact that smith's throughout time back in the practically stone age were able to figure this all out and use all these techniques with no machinery. And somehow pump out strong swords and chain mails, plate mails.
How long does it take to make a sword using this technique?
Always been the best
I really enjoy your videos, If i thought i could afford having you make me a camp knife I would be all over it, the work I've seen you do on these videos is amazing. I'll be looking for part 2 of this one.
Found you through your interview with Joe. Great video.
Outstanding, Walter!! This is an amazing video. Just what I've been wanting to see.
Wow! I always thought folding was some mystical thing.
Really cool process, can't wait to see more!
well said, brilliant.
Got my first belt grinder, some insulating bricks and a billet of 1080 today. It’s gonna be ugly but it’ll be something sharp. Thanks for the tips!
Thanks for sharing 👍🏼
Need to learn this in my upcoming career.
Ugh I wish I had this very nice sir
Suddenly I find myself wanting to learn how to do bloomery and make Japanese cutlery
I’ve read that the use of straw and ash is important to add a small amount of carbon back into the steel. What is your opinion on this? Thanks for sharing your knowledge with these videos!
I have seen allot of BAD information about Tamahagne out there, I have read many books in the Japanese sword, my favorite is the Connessours Guide to Japanese Swords, that book has a ton of information and is a great reference. I wish I could afford to have you make me a Shinken but being disabled and on a limited income, unless I win the lottery (which I don't ply) I will just have to enjoy watching you make them
What's the short cut i.e. what commercially processed steel an be made in to a katana? Thanks!
I can’t believe you turned that clump of dirt into a billet. 🙂👍
Modern manufactured steel means one does not need to do this anymore. The reason the Japanese did this was because they only had access to low-quality steel.
Fascinating! Not that I plan on making a blade, but where do you get tamahagane?
He made it himself
Any estimation (or calculation) on how much weight is lost in all those heats? Is that mostly slag and impurities or are you losing steel?
I thought it was jewel steel in english
just watched japanese guys make one and you dont get it
With all your years of doing this ' have you ever made a sword with just a hammer, not using the press
Hmmm, so the steel folding process is simply a purification process.
If you instead used pure iron in this process, there would be no benefit whatsoever.
At 8:40 he has hair then 8:49 he's bald lol
