These are the kinds of videos I really appreciate. No intro, no overbearing personality, no BS. Just straight to the point, here's the process.

[@skattyopt]

Yes so true these are my favorite kind of channels where the content speaks for it's self.

[@alfisdrake]

It depends. Michaelcthulhu's videos would be half as interesting without him talking. The guy's so damn funny.

[@BaldorfBreakdowns]

@@alfisdrake I can agree with that, but he also isn't overbearing and he's pretty straight to the point. I'm not saying those qualities are necessarily a bad thing either. I watch plenty of channels with intros, character personalities and plenty of BSing.

you afraid of getting a little cut? it heals. it only hurts for a moment. not even long enough to whine about it.

[@hellcatdave1]

@Jao Bai Dun Most knives don't require a lot of force to unlock....he's clearly struggling to unlock it therefore it is unsafe as it forces his hand to get smacked by the blade. Any good edge on the blade would slice his hand open.

[@theriveracis5172]

@Jao Bai Dun Eh, here I'd be a bit worried due to the sliding motion it gives. Knives cut best when you pull them, and so this basically looks to me like it doubles the risk. Beautiful stuff, for sure, but I wouldn't put my hands near it closing.

[@robertwillis4061]

Was shown a trick years ago by an old engineer, who had done flush riveting. For the 3 pins you peened over to lock. He would have drilled a small countersink on each side beforehand. The same as you did for the Allen screws but smaller. And once peened over, they are buffed until totally flush with the body, save getting fingers and trouser pockets caught

[@osallivan231]

Funny enough I had the same exact though as to why he didn't do that... I thought that's pretty obvious and makes a stronger bond...

[@nelsonx5326]

And when he drilling the two brass handle halves he could have soldered them together with plumbers solder then unsoldered them. But he looks like he knows what he's doing.

[@Gruuvin1]

All that work, and the brass handle/sheath was rough. Oddly unsatisfying in the end.

[@tomliemohn624]

As a machinist, allow me to make a suggestion. On your milling machine, use an aluminum sub-plate. It's a softer, disposible, plate that bolts onto your mill's table saving the table from any potential damage by drilling or milling. Cheap insurance if you value the condition of your table. And you should value the condition of your table.

[@dragonlordgaming7065]

The folding is what gets me a little bit. Because without those gloves and if you're not careful thats a disaster waiting to happen.

[@TheKyaben]

I agree. 12:10 especially got me worried. It seemed to get stuck for a bit, and then almost sliced into his finger

[@arturoortega1403]

Thought exactly the same. He did notice and folded it with the edge pointing away from him after, but anyone using that for the first time without proper protection is in high risk of injury.

[@WhuDhat]

Feels like it should be the halfway point eh

[@thetruthexperiment]

Make a better one.

[@MrTadpole96]

Well he did say its weird not safe haha

[@MadebyKourmoulis]

The only thing that would make it cooler is if you could sink the blade all the way in like a traditional folder.

[@wiklundpatrick84]

That and distal taper for balance

[@jhyland87]

Agreed

[@coldbluesomething]

I'm thinking, if he channeled a groove fort the edge in that back spacer/joint, that would do it...

[@Tristanhx]

It looks like it would be possible with this design, but the blade would have to be longer to allow for a longer groove

[@robotkabot7541]

I think there is no safety. Maybe not yet. As others have pointed out already, I too think this is more of a prototype not ready for pocket carry

[@Momoka7]

@@robotkabot7541 No, there is no safety, definitely none. This might be a prototype, but It would have been allot better if Koss thought ahead about safety to carry this in a pocket. That said, I really like the design of this knife, looks unusual while also looking very sturdy. Just sad that it is unsafe to carry in a pocket.

[@jangrzyb670]

I understand where your coming from but I only have one thing to point out he never called it a pocket knife he called it a folding knife and yes I know same thing but I doubt that’s the knife you’ll want if you either get in trouble or need for survival

[@Momoka7]

​@@jangrzyb670 Semantics. Pocket knife... folding knife... this doesn't need to be a knife with a blade that can be locked in place. I had a few knifes that where "folding knifes" in my lifetime... they all could be placed in a pocket. This here is no different... apart from the fact that there is seemingly nothing that locks it in a closed or open state. Which is what I lamented. I love the design, looks really unique. But what use is it if you can only put it on a table, or carry it in a way that is not within your pockets? You can use a pocket knife for basic stuff in survival... no need for a locked big knife. Oh and lastly... if I get in "trouble" with other people... a knife is not the right tool to deal with that. Unless you are in the wilderness and fight a animal... but then I would carry a Crocodile Dundee style "knife". Compared to that... this isn't even a knife.

[@PinkPummy]

Looks like the mechanism of the Scorpiodesign Shapeshifter, it's such a neat design. The original idea behind it was to be able to fit a blade larger than the handle

[@AHugeProblem]

@CorvoAttano

[@MildMisanthropeMaybeMassive]

Naiyuro Damascus I’d love to see a combat ready replica of Corvo’s Folding Sword made.

[@AHugeProblem]

@@MildMisanthropeMaybeMassive I have ideas in mind. A locking mechanism in the handle, and a blade that's hollow in the first portion and a taper all the way in from the spine, with a part of the sink blade sticking out to prevent it from sliding all the way down. A notch is cut down the blade and a rectangular bar is used to keep the blade straight when you swing the blade out with the handle open which would release the lock. The hollow section of the blade would be lined with leather, to midigate the blade dulling, and the hollow blade could have a bit stopping the sink blade from going all the way out. It wouldn't fold in by itself by flipping it, nor would it do the wack ass thing that mortimer rasmey is seen doing when he stabs alexia in the beginning of the second game.
