Hand forging a satoyama kotanto style blade from a reclaimed harrow tooth. This is part of a full build series for this knife.

More about the project:
Satoyama are the managed forest areas that border the cultivated fields and the mountain wilds in Japan. Historically they provided soil nutrients, firewood, edible plants, mushrooms, fish, and game, and supported local industries such as farming, timber construction, and charcoal making. Balancing the interaction of wetlands, streams, forests, and fields is an important component of the satoyama landscape and allows for sustainable use of the rich resources they offer.
The Tools for Satoyama project is inspired by this mutually beneficial interaction between humans and the natural world, a robust way of life that sustained both for centuries. Among the goals of the project are contributing to the growing awareness of the satoyama concept, sustainable practices, thoughtful approaches to intentional living, and related historical learning.
The four styles of kotanto knives designed for the project are named for the four main areas found within the satoyama landscape: stream, field, forest, and mountain. In addition, the forest and mountain models also come in a full sized tanto configuration. Some of the core characteristics of the knives produced for this project are the reclaimed and natural source materials, use of traditional techniques, and a humble and simple style of carving and finishing.
A clay tempered blade hand forged in a charcoal fire, water quenched with clay, sharpened with waterstones, and finished simply and humbly in the age-old style of farming and foresting tools traditionally used in managing satoyama lands.

I am always amazed at how quickly and accurately you are able to move metal around, both with the hammer and the file. And all by eye...
like your video's. the sound of the anvil is pretty good, just about put's me to sleep. love it. brings back childhood memory's.
glad to hear!
Amazing Job thank you for shearing, I also use 2 to 3 different hammers when forging, Oh and water on my anvil too. again thank you!!!!!
keep it up!
aren't you worried about cracks when you work the metal for so long without reheating that it gets that cold?
there are several factors to consider on this issue, which is as subtle and nuanced as any other metal working skill...one is that even when the steel looks black in daylight it is actually still at a low red heat, another is the type of alloy as some tool steels cannot handle low red forging, another is the type of forging as major movement is best done hot but smoothing and planishing is better at lower heats, and another that there is a certain feel that comes with decades for what a piece of steel can handle as the lower forging limits are pushed to create a refined grain without causing cracking...
It seems like there is a different ring to your hammer and anvil, out of curiosity what king of metal are your hammers made out of?
just (tool) steel like all the rest...the one i made is from an old axle...ring depends on size, shape, hardness, and what is being struck...anvil heels usually make the most noise...
Nice work.
Sorry, may i know where can i get the tongs on 1:35? I am forging on my own, your video really inspired me. Thank you so much.
there are no blacksmiths for blacksmiths, you can make your own tongs just the way you need them! ^_____^
if I have anything to say, it's that you should have used the bracket that was on it as a tsuba, in the tradition of reusing.
indeed! this one needed a copper guard though...there will be more!
What steel is this harrow tooth of, I wonder. You must be confident about its' simplicity. Steel is such alchemy compared to precious metals; and such a mountain to climb.
My hens quit laying if I hammer all day.
if you please tell me what is the difference between these 3 hammers because i think one hammer will do the job..??
weight! ...and face size...yes one hammer can do the job but if you start with a heavier hammer you can move material quickly and the force impacts more deeply into the steel (the opposite of riveting)...later on a lighter hammer is good when you are trying to be more accurate...
I hate to bother you again, especially on the same video, but isn't it technically just a piece of steel? Since you didn't do Yaki-Ire?
here's the full overview, or stay tuned to watch the longer version of the next stage: ua-cam.com/video/1VqXZgLwnRo/v-deo.html
Thank you again! I'm a learning blacksmith myself, and I look up to you. So it's great to have feedback from someone more experienced!
I hear you have peacocks at the residence.
good ear!
cool
why do you switch between hammers when finishing tang?
did i? heavier one moves more material, lighter one has a flatter face and is more accurate...
What could one do with a kotanto?
the concept is that it is kind of a humble everyday knife with the pedigree of a classical tanto...
oh, that's pretty cool
nice man!
Why add water on the anvil?
it keeps the iron oxide scale from building up on the surface and scarring it...
@@islandblacksmith to prevent scale buildup?
yes, the steam cleans it from the surface..
уж больно мягкую сталь используешь для клинка...
how do you know? ^__^
знаю . изучал .@@islandblacksmith
studied what? the piece of steel in my forge? what is the carbon content? or what is the final hardness of the edge? ^__^
количество углерода в аналогичных деталях.@@islandblacksmith
do you know what a harrow tooth is? this is not a bolt...the way to tell if something is high carbon is to heat it red and quench in water, then test if it snaps or bends...snap = >.5, bend =
Muito bom
a UA-cam page known as dexterity has stole one of your video's and uploaded it on their page
thanks, Gabriel...not much i can do but i will leave them a note!
Crossed Heart Forge - islandblacksmith you can report them UA-cam will take the video off and they will get a strike on there record if to happens too many times the channel will be removed
