Compliments, Sir! I am a teacher of thumb archery and from Your video I have learned a lot more, than I knew before. I will share this video with all my students. Thank You, Sir!

Excellent video. Thanks for putting the time and effort to produce it. I have been shooting compound for 30 years and only recently started down the path of Asiatic archery. I'm always looking for new material that can help me learn and this is the best detailed explanation of Khatra i found.

Watching this 3 years after posting, and you are explaining it the way I understand! Very good job, I hope you are doing well.

Thank you for the detailed explanation. This was exactly what I was looking for.

Thanks for this. Informative, helpful for me and very clearly explained!

best video I've seen on this subject. Very tight on detail and presentation.

Totally awsome explanation of khatra / thumb draw / spine correlation. I've been googling several hours by now to understand why everybody says different things! Thanks a million, dude! So, if I understand corerctly, this all actually means you can buy whatever spine you like. (as long as it is not so high to damage the limbs) and then just practice. For some arrows you'll do more khatra, for some others little khatra for some arrows no khatra etc...

Thank You Very Much 🙏

I learned a lot from this video. Thank u so much. Subscribed

An extremely clear and complete explanation--thank you so much!

very very good. Thank you for taking the time to do this.

You did a lot of research for this video . Very informative. Good job!!

Thank for sharing. Good introduction

WELL done! Very instructive!

This was an awesome video. There are many videos that explain how to do khatra, but not many explaining how it works or why with such depth. Thank you!

Spot on for all accounts. Detailed- everything is substantiated and clearly describes the dynamics involved simply. Thank you for this.

Excellent explanation of khatra and archers paradox and arrow spine. What you mentioned at the end about manchu bows and the possibility of even unstringing them is also applicable to turkish bows (I found that out from experience).

Excellent information. Thank you.

Thank you so much for this instructional. Best explanation of archers parodox I've seen so far. Extremely interesting and inspiring. I just want to go and practice with different arrows 😊👌🙏

excellent explanation!! Thx!!

this is the most educational video I ever seen I am watching second time and propably need to watch more times but now I see problems I do my khatra is the third one pushing bow down and turning it but much more agresive forvard and sideways mowement I also tvist string on my thumb much more than is propably necessary :D but my arrows are same soft spine I used before I start using khatra :/ so next batch of arrows I try much harder shafts and seeee what it do to my :D I am realy thankfull for this much of information ande said way I can understand

Very nice video, your explanation of khatra is the best so far on youtube

I join to all others, who write that this is THE most informative and the best video on the subject out there. I learned a lot of it. It would be even better with some examples of shooting in it. But for me it is priceless. It explains with solid arguments of physics, what khatra is, why it works, and even addresses its weaknesses. What Armin Hirmer, for example asks and wonders about, is all answered here. In just one video. It even answered some questions of mine, which I had for our classic European way of shooting. You get all the high marks from me, and a plus at that. Thank you very much for your knowledge! Keep up the good work! I am your new subscriber.

Very interesting and well presented. Thank you for posting.

Absolutely FANTASTIC content

Brilliantly clear explanation. Much respect!

Thank you so much! This was the best explanation of Khatra I have seen! This will help me a lot with my draw style.

There's a lot good information in this video👍 thanks for making it available to those who wish to learn more about the subject.

Very nice. Comprehensible and detailed. I like it.

OOOOHH Thank you ! :)

Thank you so much. This clarifies a lot

Really an excellent explanation.

i agree with the other people. your explanations are really clear and make sens !

I liked that. One of the best explanations of what happens to the arrow and it's relation to the riser I've seen, so far. Though personally, I think that the paradox only exists up to the moment you release the string. Everything afterwards to me was just the explanation of what makes it a paradox, to begin with, and how we have learned to compensate for it throughout history in different cultures.

Very informative and I imagine that finding a way to balance all of this would produce the best overall technique.

Hello sir: I was practicing this evening with a better thumb release protector, and getting tighter groups but all going more to the right side than before. And i noticed a consistent slapping sound, and also, the arrow wrapping was wearing out in a thin line where it has been contacting the bow at the fletching end. Even though the spine should be okay. So i was thinking i need to do more research, (maybe something more than just adding weight to the tip) and found your video. Now i know the purpose of the katra. Seems the spine is not enough! Great intro into this kind of shooting and what is actually happening. Thank you. Randy c

Thanks and respect ! Hurrah ! Hurrah !

super

man you should do a "how to do khatra video". i would love it so much

A very good video, thank you. You packed a lot of information into your presentation. I appreciate that there is not distracting background, and no attempt to prove your points by showing the techiques - this would just lead to viewers attempting to criticize someone else's shooting because it is different than theirs - but presenting them in a factual manner and letting the facts and physics speak for themselves. Unfortunately, the volume is a bit low, at times you are hard to hear (at least on my computer). However, the 'Archer's Paradox' explanation is a bit off - do not confuse or mix up the paradox with the arrow oscillation. As a point for further consideration to finetune your analysis of the impact of release on the bending of the arrow: look at the angle between the theoretical line of string travel and the arrow shaft at full draw/with ideal clean release (e.g. with mechanical aid) - upon release, the force vector of the string is not in line with the shaft, but at a slight angle, directed into the bow. This is why even with a mechanical release in a non-centershot bow, the arrow first bends into the bow in its first oscillation. The motion of the finger(s) or thumb can then exaggerate this initial motion and together with the static spine character of the arrow will result in a weak or strong oscillation of arrow during flight. - I liked your scientific approach, well done.

Thanks for this. I now have a better understanding of how khatra works and why. It also explains why my arrows always go so far right (I'm a right-handed archer) when I use a Slavic draw. When the arrow reaches the riser it is actually curving away from it rather than around it and since the arrow is on the right side there is nothing to stop it from continuing to go right (I think). My thumb draw does not have this problem and I was looking for an explanation.

So for aggressively siyahed bows with prominent syring bridges, would a manchu type release be useful, or just overkill. I get by with gentle side khatra but I get a little arrow lean to the left. I use stiff arrows. maybe ill put more spin on it or twist after listening to your advice

Super informative and clear! I have a question though. If the arrow is released 100% clean with a mechanical aid for example, the arrow will still paradox it's way around the handle right? If that's true then similar to finger release on a center cut bow, thumb draw release on a narrower handle, or near center cut shelf on the draw hand side, could require less or no khatra to achieve straight flight? Thanks!

Amazing information! Do you have any knowledge to share about the Japanese yumi bow and the way it is rotated?

I don't mind watching this video over and over, but do you have this information in printed form or an e-book? I would happily pay for it.

Had to listen past the accent but it was entertaining.. good content I understood

what is your draw length and height? I'm thinking about getting the bamboo bow you have from Mariner. thanks

what guarantees that the flexing arrow will flex away from the handle and not towards it? Why doesn't flexion of the arrow disrupt flight sometimes? for example why don't arrow flex in such a way that they smack into the bow?

Correct about 90% - however the armor penetration part is not. The physics logic is sound, however the practical application of arrows vs hard armor (not chain, padded, etc.) but plate armor is wrong. Arrows used as shrapnel "grenades" against hard armor was very much a thing. Tod's Workshop did an investigation which demonstrates this, and what measures were taken against this shrapnel.
