  1. Heat treating with a gas forge - some questions

    Thank you guys! Hehe, well, I haven't build the forge yet, I'm still waiting for the insulation material to arrive. I'm planning to build a venturi burner, but I have not yet decided which one to pick of the hundreds of tutorials and how-to's that are out there. It is really confusing for a beginner. Another question arose about heat treating 1095, I'll just ask it here if that's okay: Is it really essential to give every blade a 10 minute soak at 800°C / 1475 F ? Because saving that time was the main reason I wanted to get a bunch of blades in there at the first place. Also, is there any difference in that soaking time if there is clay on the blade? I'm sorry, but there are so many things I haven't really dived into yet...
  2. Heat treating with a gas forge - some questions

    Thank you very much Tim for your detailed explanation of this great idea - but it's nothing for me, as I want to use my forge also for - well - forging, not only to heat treat. Also, @Al Massey, you are right. I've dropped my idea of wanting to throw a bunch of them in there at the same time. But I still have a question about heat regulation: Should i rather check the forge's heat with a thermocouple and try to aim for the right temperature inside needed for quenching, or should I rather check the heat of the blade itself by taking it out of the forge and measuring it's temperature with a hand-held-temperature-measuring-device-thing? (i might add that I do not know the name in english ^^ )
  3. Something different from me... not really. But I like it.

    The design and flow of your knife are outstanding. The only thing that caught my eye was the sheath, I think that burnished edges would look much cleaner Oh, and, what is that type of sheath called? I have to try this mix of folded and stacked leather as well!
  4. Heat treating with a gas forge - some questions

    Yes, I think i should stick to exactly that. Thank you for your insights guys, they are very valuable to a newbie like me.
  5. Heat treating with a gas forge - some questions

    Thank you Alan and thank you Brian for your warning, it might save me from some moment of stupidness. I have an idea about several 5x2 cm steel tubes stacked together to get several blades hot at the same time, would that be a possible thing to do? Or does it only work with pipes? (Excuse the quick sketch, I hope you get the point)
  6. Heat treating with a gas forge - some questions

    Thanks everyone for your information. I see, hot spots are going to ruin my initial idea. About the blade-inside-a-tube-thingy , would I dunk the entire thing into my quenchant? I'm also kind of worried about the tube removing my precious clay outline Once the forge is heated up, how long does it approximately take to heat up a medium size blade (moving it around inside the forge to prevent hot spots)? Of course this varies from forge to forge, but a rough guess is better than nothing.
  7. Heya folks, I am currently building a propane tank gas forge like the one in the picture below. I am also planning to increase my knive production rate to be able to make a little money with my stuff, but I do not yet want to invest several thousands of dollars into a heat treating oven. Now i was asking myself the following: Is it possible (and reasonable) to use my soon-built forge to harden several blades at once? Can I control the heat in there by sticking in a thermocouple sensor and adjusting my burner? I am mainly going to work with 1095, and Im going to stick in a lot of clay-covered blades for hamons. So, for example, would there be any problem with the following scenario: I put 5 clay-covered 1095 blades into the forge (using one of those blade-racks), heat the forge up to 800°C (which is, as far as i know, the temperature to harden 1095 at) and then try to let the blades soak at that temperature for 10 minutes by regulating the heat via the burner. I hope someone can give any advice on that topic Cheers, Jonas
  8. 1095 Hamon doesnt show - reasons?

    Alright lads, thanks for your advice!
  9. 1095 Hamon doesnt show - reasons?

    Thanks guys for your information, I know of course that my setup isn't the best, I'm working on a better solution right now. I think the entire thing hardened, and i have polished the blade further which revealed an interesting pattern after etching, Its not the hamon, but rather... bubbly? What is that, a sign of overheating perhaps?
  10. Heya everyone, I have recently tried to achieve a hamon on a full flat ground 1095 knife blade. I have done a few hamons before with no trouble on kiridashis, but this time nothing happened. There is nothing to be seen on the etched blade after hardening, and I am not sure where I went wrong, so maybe someone can help me out: Included are pictures of the blade before clay layout, with clay applied and after hardening. The clay outline was about 1mm thick, so not exceptionally thick... I used canola oil for quenchant which was pretty hot, because i quenched two regular blades in it before. After hardening and tempering i could see some heavy scale that went down pretty deep, so I had to grind a fair amount of steel away, but not that much. After polishing and etching there is NOTHING to be seen... Could it be the thin clay outline? The high oil temperature? The grinding away after hardening? I have no clue and Im a bit lost. Hoping for some help! Cheers.

    Gorgeous! Cant wait to see it finished.
  12. Show me your first knives!

    Its nice to see you all share your first work! There is an interesting story behind each one of them.

    Nice! Is the clay pattern going to remain your secret?
  14. I introduce myself and present my last work

    I like it very much! Great job
  15. How do you think about this fancy design?

    Good lord, thank you for this name! So much inspiration to soak in!
