The Super Tong-Ah (Crab Bow on Steroids)!

[@jyahn8059]

OMG It is a pleasant surprise to see Tong-Ah and Pyunjeon review here! You see, Tong-Ah and Pyunjeon had been secret weapons for a few hundred years in my country (Korea). Pyunjeons, the short arrows launched via Tong-Ah have lots of advantages: 1. Pyunjeons are much faster than conventional arrows. In the recent tests performed using traditional bows, Pyungjeons marked 77~90m/s, while the conventional arrows did 60m/sec or less. 2. Pyunjeons fly much longer than conventional ones; they reach 500m or even more with traditional bows. 3. Pyeonjeons are more penetrative than conventional arrows. Whilst the weight of a Pyunjeon is 4/5 of a conventional arrow; its speed is 30% faster than a conventional one. This results in greater dynamic energy and penetration. A traditional record says that a Pyunjeon could kill 2 soldiers within 48m. 4. Since Pyunjeons are shorter (roughly a half) and lighter than conventional arrows, archers could carry more number of shots. 5. Enemies could not reuse Pyunjeons as they did not have Tong-Ahs. 6. As Pyunjeons are faster and smaller, it is very difficult for the enemies to follow their trajectory and react. Hope you enjoy my comments. Thanks!

the idea of a bow magazine that you can just use with any bow with zero installation sounds amazing. great idea! Something I've always thought about Joerg is that he is three professions in one, which is amazing. Usually you'd have and expert in engineering, fabrication, and assembler/mechanic . The engineer designs, the fabricator makes the parts, the assembler/mechanic puts them together and maintains them. Joerg does all three.

[@hansvonmannschaft9062]

And a fourth one: An excellent and professional salesman! Can you think of anyone who hasn't allowed him to show them his inventions' features? Haha! And who wouldn't want to buy his inventions? They're so good they pretty much sell on their own!

[@hellomate639]

I look at it the other way. Craftsmanship has been shattered into engineering, fabrication, and assembly. The modern world is fractured, and it's part of why we're depressed.

3:18 it says "rapid(fire) Japanese bow" (shunsokuwakyuu). Pyeonjeon was a shorter projectile that flied faster. Once landed on enemy formations they weren't "compatible" with their bows because their archers wouldn't have had the tong-ah and the necessary training to use them, let alone a sofisticated contraption you've used to shoot one.

[@jeonghwanlim3144]

Excellent idea! I particularly like the thought that it could be usable for almost any bow, but of course you'd have to take the different draw lengths of the bows into consideration. If you went into production you could certainly count me in!

[@username82765]

Love it. Would definitely buy it. One recommendation... A small thin handle to hold it in place before and after you draw the bow. So you could easily move around with it.

[@AmadaHiroshi]

If it can be quick detach it could possibly be a bow magazine with different kind of arrows. You are amazing as always.

[@hasanmousa4235]

Please continue developing it!

[@wizzardrincewind9458]

Not only shorter arrows or bolts, but much thinner arrows and bolts. This thinner arrows/b. can fly faster, a longer distance and can penetrate better and you maybe need no feathers (if they are more front heavy?)

[@KerekesJanos-yw5iw]

Hey there! It's great to see Jörg back in action, making videos like in the good old times. 😄 As for the Super Tong-Ah (Crab Bow on Steroids), it's a really interesting concept. The idea of having a versatile reloading device that can work with different bows is quite innovative. It's a nice blend of traditional and modern archery. I'd love to see more developments on this, maybe with a sleeker and more lightweight design. What do you think? Keep up the awesome work, and looking forward to more exciting videos from Jörg's channel! 👍

[@puddingpoppalpatine-6070]

It's interesting cause my mother would always tell me stories of the why they used the "baby" arrows. Apparently they were quicker, making them more deadly and they couldn't be cut out of the air by skilled swordsmen unlike normal arrows. That last part might just be for the cool factor but it's nice to know the stories of my childhood are reaching a wider audience.

[@thebravegallade731]

A real kicker is that your enemies can't scavenge your arrows to use against you

[@musikSkool]

Joerg, have you heard that you can increase your penetration if you use do a paper test and use an arrow tuning chart? Hunters have even hunted Elephants with a bow and arrow because they maximized its penetration. They also use Ashby's 12 principles of Terminal Arrow Performance. He did archery testing for over two decades with many different bows and arrows to find the best penetration. He sells an arrowhead that takes all that into consideration, but I would personally just buy cheap arrowheads that take advantage of the same physics principles that he discovered.

[@vitorpimentel2145]

Cool ideia. I still think the adder is your most elegant design, though

[@Face-bb5ix]

I think a problem with this unmounted SIL for many archers using asiatic bows would be the draw length. Because of the grip you lose like 3 to 4 inches in contrast to a thumb draw, so most people might end up with a 28" draw instead of a 31" one. Since many bows in this style of archery are designed to be drawn out that far - and even report their poundage for "full" draw instead of the western 28" - using this device would severely reduce the power you get out of the bow. However, for longbows or even horse-bows with 28" draw design, this looks like much fun! Cool idea, as always.

[@Lost_Hwasal]

The tong-ah was for shooting smaller faster arrows. The KTB, like the turkish bow, is very good at shooting light arrows at fast speeds. Korean archers had smaller arrows specifically for use with the tong-ah.

[@HistoricalWeapons]

Don’t forget the repeating crossbows Koreans used which serve the same function as this

You know we love the Legolas and it basically made you the German Ninja Assassin. However the last person that I've seen mess with the Tonga was Backyard Bowyer and he's been going through a hard time with a divorce and stuff very sad we miss him dearly. KZbin railroaded everyone in the weapons community. I'd really like to see if you can come up with a version of this tonga rail old school for a diy. PS your best diy invention is the slingbow with a D loop I don't care what anybody says I love that Woodcraft build. Your voice did sound a little bit shaky I hope you're doing okay bud. The conservative viewership they call us the silent majority in America but worldwide were very small in numbers and we got to have each other's back. You're the best at what you do and I'm glad you do it.

[@Samtagri]

Would be interesting to see how you can walk around with it without taking the string out. Because you can tilt the Legolas system (because it is not bolted to the bow). So you can potentially walk around with it being just the size of the bow with the Legolas parallel to the bow, then as soon as you want to shoot it you grab the Legolas perpendicular to the bow and shoot.

on many 3D-Archery grounds in my area, Compound Bows are prohibited. .. so having an instand legolas for a "normal" bow would be really awesome! On top of that, as someone who only does archery with medival bows, I would love if you can make it "adjustable" it, so it the takes thicker wood arrows.

[@blackguard5883]

A belt, like a literal BELT, braided parachord even, in front, would help SO much with fire rate. Yes, the setup time is longer. But just align it proper, cinch it down, and fire almost as fast, if not just as fast, as the locked-in models? That would sell it for me. Either way I'd call this a very worthwhile concept. Good luck with it Joerg.

[@gw2macken757]

Did I ever tell you you are a genius.

[@jaguarholly7156]

It's not as much of a problem with a mostly fiberglass bow, but just so yall know, shooting very light arrows is basically dry firing your bow. So this will cause far more wear and tear on the bow and in the worst case, actually destroy the bow.

[@arkhtyi9456]

Yes. A very known problem with the Tong-Ah too, which is why they used standard arrows for, well, standard purposes and the Tong-Ah was only used for special occasions

[@rur1597]

Tong-Ah has way more penetration power than long arrow. This means Pyunjun(short arrow) shot with Tong-Ah, a sort of long gun barrel, is more fatal in a battle. Korea has a long history of winning wars against her neighboring giant invaders and many believes Korea has had more ammunition power than her invaders. Incredibly strong power of Korean bows combined with Tong-Ah, a gunbarrel for arrows, brought advantages over less powerful bows with plain arrows shot without barrel. Check the power of Tong-Ah from many experiments on KZbin. One of them is kzbin.info/www/bejne/eajSlWCjZr6fgrM&pp=gAQBiAQB
