Floh : Sure you can have more than 1 Joule with a Airsoft =D

Michael Dilger : Please Cut up a lipo

gagomand : I love your consistent uploads, hahahaha. This is so good! Greetings from Denmark!

Robert Kitchen : David I would like to see the rocket knife cutting through a DJI phantom 1, whilst hovering.

Jim Clark, N5QL : Cut a chicken. Use hay bales for a backstop.

Jonesy Films : Nice David, adjoneses here, I think we all just found the solution to the North Korea threat

BLeeKiis Too : Every time I watch another episode of Rocket-Knife I think of yet more things I wanna see it take on! This time, I'd like to request a motorcycle helmet- WITH a ballistics gel head inside it... 3:) Thank you again :)

Low Elevation RC : "I've always wondered, can you actually hotglue a watermelon to something?" Uhh... Yeah, I've "always wondered" that too

Daniel Tomas Jr. : Put a mattress on a cord, lead. When the rocket hits, the mattress moves but is connected to the cord. It will slow it down. The easier the better. The physics are there.

Kevin Hornback : attach the gopro to the sled

Gustavo Hernan : You have a new sub

Ryan Korniloff : I wonder if the sled is long enough for the rocket to reach it's top speed...

Peter Aksberg : Cutting stuff is nice but can we see it from the sleds point of view? Probably need to work a little on the catching to make camera survive before trying but I guess it would give you a good opportunity to study the knife wobble.

Anas Mhz : who loves david windestal ? his such a great man

matt Yapman : you better add audio effect like sloma guys to get more viewers

iwa : デビッドがおっさんになっとる。

Bogdan Markovic : U need a better slow mo camera its a waste of time if u cant see im super slow motion....chronos would work for you. I pretty sure you r familiar with that camera. Its cheap and good

Markus Lindblom : Why you upload so early in the morning

Detour FPV : This is why I buy from rcexplorer. David's madness needs funding.

HorrifiedPilot : Cut a rocket knife with a rocket knife.

Air-headed Aviator : "Lets watch it in slowmo." *rocketknige still zips by.* Also you should cut me up a piece of pie with that Rocket Knife David, to celebrate!

zendell37 : It's like Henrick is a cliche Swedish party guy. That's not a knock, he's a rad bad dude.

Claes Wikberg : David you are a smart person... 3000 joule and you expect an old mattress to stop it... ;)

Hampus Mellin : What fuel do you use?

PressTube : Subscribed !! What high speed camera are you using? First time on this channel so maybe it's been said before, in that case sorry for asking.

Jan Hoffmann : Pls cut a old Nokia. I know its not posible to do that because they are unbreakable.

Alec J : I'm curious if you calculated the charge's burn time and constructed the track length to coincide with that.

Jamie Feldman : David, Please Please Please do spray paint cans!!!!!

Kumra : Rocket Knife vs Deer

Gunner R.A. : Just a thought, is the knife generating lift on one side? Might be why the cut is on the tilt. Also you are INSANE!!!

Christopher Raff : Deer: I'm going to get the hell out of here; that guy has a knife with a rocket attached to it! No way this ends well for me.

Giaco Whatever : I love that you put it in the centhor...

johnny llooddte : please..... dont ever lay down near that monster again

The Smug Doge : Backyard scientist?

stotheh : Cut an iPhone. I know it's a ripoff but still...

1041ferret : will you circumcise me with this plz ? <3

g2h0 : David has always been a cut above the rest

chazzbass : to much time on some of our hands

Dylan Fisher : What fuel do you use?

Airborne Images : Try slicing a water balloon. The high speed should be great.

ald88cod : What are you using as ur fuel grain

Jimmy Sippel : Coolt David! 😀 Jag är väldigt nyfiken på vad du har som bränsle till raketen? Har försökt leta om du lagt ut den informationen här någonstans men inte hittat något. Har lekt lite med socker raketer förut. 😉 Så det hade varit trevligt om du ville dela med dig av vad det är för bränsle på något sätt. Jimmy / CarbiX

muh1h1 : You should definitly consider putting an actioncamera on the sled itself next time you cut something!

Ian Davidson : Shouldn't the guide-rail continue PAST the object you want to slice?

Luisangel Corona : nice work!! I think it"ll cut 5-10 watermelons easy!! maybe a pineapple next?

Muele : Awesome geek-work. But you need to watermark your videos. They are beginning to go viral in GIFform. Watermarking is probably the only way you can get those viewers come here and see the full videos.

Ghost Ryder FPV : Hello David! May I suggest, for your next cut, a North Korean ICBM?

Glen Bellows : How is that knife not destroyed yet

Constantine Bovalis : Maybe put multiple watermelons along the line?

B4its2L8guy : A pig head. Perfect gore fest.
