Any questions or items I missed answering in this video?

Very good information, thank you Dennis.

Great video Brother!!! You answered a lot of my questions! Thanks for sharing! 🔥🙏🏻☯️😎👍🏻

[justingoodman]

Great info! Most of the people complaining about not forging to shape are just telling on themselves. If they knew what they’re doing, they would know better. Just like the guys who say stock removal isn’t as good quality as forged. We’re not using ancient steel that needs to be forged to compact the layers and get rid of impurities.

Great tips! I learn something new on all you're videos

[valeharperx]

Really great video! The rule of thirds makes a lot of sense. I'm actually about to "weld" a few combinations of steels inside a HT Oven and create a diffusion bond, then perhaps draw out some of those pieces and cut out some knives out of them later on. I don't have a press and it seems worth it to do it this way. The rule of thirds will help me figure out how to construct this project properly, cheers!

[RRINTHESHOP]

Great info. I liked the drawing explanations, very understandable. Thank you for sharing.

[beausmith]

Great video, especially the theory of forging in bevels and how that impacts the visibility of the core. Thanks

[aviweisbach]

Thank you for this! I am just finishing up a couple fairly unsuccessful Go Mai blades. Your video will really help on my next attempt.

[SwitchbackXThunter]

Excellent video Denis! I was curious about the heat treating, and you nailed it. Thank you!
I’m attempting my first Cu Mai when it’s not so hot here in Florida, and excited to see the results.

I have to make chainsaw chain canister Damascus knife for my son who is a tree arborist. I’m using some of his used chains to make his blade. Maybe one day if you attempt it, please do a video. ☺️

As soon as it cools off some I'm going to fire up the forge and give this a shot. I was about to buy a press but I decided to get a boat motor instead. I guess it's hammer time. Thanks for the advice 👍

What i like to do with gomai or sanmai constructions is roughly grinding to my core steel with an anglegrinder after forgewelding and then beveling and forging to shape. This ensures i have my core on the edge everywhere.

[mulepowerforge]

Ive done 2 san mai knives and Im working on my third. Pretty surprised theyve all came out perfect so far, even though Im self taught with no experience forge welding/laminating steel. On my first one I learned that thinner core material doesnt make the best san mai so the next two I used steel the same thickness as the cladding (thirds). Entirely hand forged in a coal forge too which is a workout.

GM je ne parle pas anglais je m excuse je suis votre chaîne je suis un grand fan j'aime la coutellerie et vos techniques merci

[NorthIdahoKnives]

1/3 rule is great! that will help😄. Have you ever tried a bronze shim? I have tried a couple times with no luck.

[jasonvliet-odonataknifeworks]

Good info as always! As I understand it(correct me if I’m wrong), layered construction with soft metals like nickel or copper isn’t actually forge welding. The soft metal shims act like solder and bond the jacket to the core? That said, would there be any benefit to a rougher surface finish on the core and jacket faces that contact the shims?

[DaRealdioactiveMan]

Really cool video. Thank you for that. Do you got a video for home shop hobby black smiths? Like how to make damascus with an anvil, regular hand held hammer and a gas forge. Maybe Borax.

[alextopfer]

Wouldn't a thinner core with cladding closer to the edge provide more support for the edge? So there would be more effect from the tougher cladding?

[glebtcheslavski]

Denis, meant to ask you for some time: is it possible to use, say, 304 for cladding? In other words can an asustenitic stainless steel be forge-welded to a high-carbon steel? Thank you!!

[NelsonJ]

What is the thickness of the shims (mm) that you use?
