This guy is a surgeon with the angle grinder. Very skilled use in every video!

Watching his video makes me feel like “ I can do that”.... I can’t do that!

Ah yes, the finest of bladesmith tools: the anglegrinder.

Out of all the knives you've made on this channel, I think this is my favourite. It sets a nice balance between gorgeousness and functionality to me.

I love the custom jigs and tools such as the zero clearance table rasp awesome tricks that really show the seasons under his belt

I can't get over the design... How clever it really is... And the finish is well done... I would like to purchase one some how!

I am really getting a lot of enjoyment from these unusual mechanism videos.

Your creativity is always so amazing

just love the whole process,thank you.

This is downright my favorite knife design

This is great! I have never seen a folding mechanism like this for knives. It appears to be the best combination of friction folder and slip-joint. Stronger too!

This knife is super sweet. Love the design.

That knife is really slick, smart and original. Really impressive design and craftsmanship especially considering the relatively crude tools you used.

Lovely! Really like the aged brass handle. I have a production knife that uses a similar mechanism, but yours is much more attractive.

Nice little grinding jig. 👍 Beauty results! Gorgeous blade.

Hands down the coolest knife I’ve ever seen

that's one of the coolest knives i've seen in a long time! well done!

That's insane. Never seen your channel before but just a few days ago I was thinking about if a knife like this was possible. In my head the top part would be similar but the buttom part was about halfway up the handle and split so the blade could pass through. I couldn't figure out how that work work without being flimsy or having too many moving parts. I didn't know this mechanism has a name or anything but this morning I wake up to this video. UKposts algorithm is freaky.

Koss, you should make a negative cutting angle on your drills when drilling brass. Works much faster. :-) thanks for the video!

You sir are very talented. Amazing video. Everything is precise.

What a beautiful piece of functional art

Simplicity of known principles, wise choices in materials, and care for detail show how well this was thought through. Well done, sir.

That is a cool design! Nice work, beautiful knife!

When the power drill held by a table vice comes out you know it’s time for the good stuff

You are so precise with your angle grinder

I love your projects, I wish I could do that

Masterpiece of practicality, definitely building this when I get my next metal sheet order in

Always doing a great job! You made a really good knifes! Thanks for your videos!

这个机械结构真的是太棒了，超级喜欢这个刀

I love these kind of videos 🥰 there so satisfying 😌

Legendary every time

this is such a sick design. i would definitely buy one

Haven't seen a folder that looks like that before and I really like the way it works Enjoyed your video so I gave it a Thumbs Up

What a well thought out, handsome, regular use pocket knife. Congratulations 👍🏻🍀❤️

precise machining - talents and skills - master level achieved

Never saw that type before and well executed!

Love this design..... I would love to see it w/a titanium or carbon fiber handle.

You are amazing with that grinder.

That is a super cool knife to carry around.

That's some high quality work right there, so simple, so beautiful.

Love it! Nicely done as usual.

11:24 - It's fOcking geniuosly!!!!

Impressive skill you have there!

Genial. MAESTRO se merece mis debidos respetos y felicitaciones.

you should put your makers mark on your projects sir, love it!

Did he really just show off the knife in 2x speed

Nice presentation of lever knifes! Good job! 👍👍👍

Nicely done. Something different for a change.

never thought that metalwork is fun until i started watching this videos

Your videos help me sleep at night, it’s like some form of weird ASMR for me

What an awesome design, realy love the mechanism! Fantastic job!

Very cool knife, well executed design!

It’s a great design can’t wait to see more of this improved

It's such an interesting concept.

Excellent job with the angle grinder 👍🏻👌

Dude! Freaking amazing! Your little Dremel/drum sander setup is brilliant as well, definitely going to steal that idea!

Impressive and unpractical, just how I like it. Awesome work man!

Beautiful work, man.

I love interesting knives would love to have this for my collection. Very nice

Each and every one of your knife is unique and super.

I love that beveling jig.

Awesome informational educational video experience Y'alls God Bless Ya

Оч интересная конструкция и не особо сложная. Классный нож.

If you added a thumb stud to the part of the frame that “locks”, could the action be operated that way?! Would be interesting visually when opened. Push thumb stud on the side, blade opens without you touching it or having any fingers exposed. Really like this design. Keep it up! ✨☮️💟🕉✨

CNC man's skill. Great 🔪

Awesome work, knife looks great

Intriguing design. Well done!

Здорово, мастер не только золотые руки но и классный конструктор получился хороший выкидной нож из добротного металла!!!😊😉😄😃😀👏🖒👍👌💪🏅

So cool you should make a OTF spring loaded w your style added

Are there plans for this knife? I would love to make my own!

Like the fact that pivot points all have washers. True understanding of basic engineering is rare these days.

Koss is always amazing with his concepts. 105 dislike because They Cannot Even Made A Knife But Watch Koss UKposts Tutorial. J-Ass

man!!! I'm trying to model it on solidworks, WOW!!! too clever ideas and much mathematics in it, plus i like how you handle the angle grinder...

That is a very cool knife build on a well made video.

This is amazing

What a great job!

Very nice. No springs, but still a safe, solid lock-up when open or closed.

Wow, it was very hard(i think) but the result... Just wow

Genius design

Super cool idea

Really great work!

I love it so much!!

This is Mesmerizing

very nice work, beautiful knife man congrats

You are making awesome knifes bro👏😍 Respect from Serbia❤

This is really wonderful

Very cool and unique design lv it

Руки с правильного места ростут 💪🏻

Great design!

Beautiful job 👍👌

The most impressive part, honestly, this dude’s ability to run an angle grinder. Makes me feel like the kid who eats crayons.

WoW sweet, I want one

beautiful!!

Fantastic work, dude! Beautiful knife!!! 😃 Stay safe there with your family! 🖖😊

Cool little knife. I like it.

Great full ideas

Good stuff! Need a better look at that grinding jig!!!

Beautiful

What a wonderful creation. I wonder if it passes the slip joint rules for the uk?

Magnifico trabajo ... me suscribo. Saludos
