    I have recently gotten interested in the hobby of knifemaking, and have been looking to set up my own small propane forge. I have talked to a professional blacksmith, and he recommended I use a coal forge. I would do this but I don't have space or recourses to do so. I now am here looking for a reliable burner for a propane forge.

    I have seen some people on other forums recommend the 'Bernzomatic t8400' but I was looking for some other opinions and recommendations. I have a price limit of around 75$ so ideally I would look for something a bit lower than that.

    You can build one, but I don't have a lot of tools or experience, so I just bought a venturi burner from Atlas Knife and Tool. You can order it with the fittings and regulator that will hook up to the standard propane grill tank they sell outside supermarkets and such for home grills.

    He offers 30k, 100k, and 150k BTU burners. I guess which one you need depends on the size of the chamber you're trying to heat.

    The Bernzomatic provides only enough heat for a smaller one or two brick forge (2BF) with small chamber. You could get up to heat treating temps for carbon steel in maybe a 1 1/2 - 2 x 8 - 9 inch round chamber with the 30k which was my experience. Probably won't be hot enough to reach good forging temps for larger chamber with just the Bernzomatic. The 30k BTU burner from Atlas will work pretty good in that 2BF from my experience.

    The 30k BTU burner with regulator is $60 plus shipping. Much better use of your money than the Bernzomatic torch, believe me since I've used both...

    I got tired of the 2BF and bought an Atlas Graham forge for forging which is pretty nice but obviously not as cheap as DIY 2BF.

    I'd second Atlas Knife and Tool if you want to buy a burner. Easy plug and play. He has an excellent reputation and is a #bladeforums member. Very helpful on here and seems like a genuinely nice guy!

    If you want to build a Venturi Builder on the cheap... you can try this design:

    Yes, you can buy a professionally made burner and regulator for about the same as the TS8400.

    Sorry, not around as much as I used to be. Too many social media platforms to keep track of. I really cant add much more than what was already said. I have extra ports, so if you order a burner I will include a side port to hold the burner. Just add it in the notes.
