- Being a fan of LTT of a long time, I was excited to finally watch the LTT Screwdriver video. To my surprise a lot of his struggles in making this screwdriver are the SAME pitfalls as many others. SO many clients come to us asking to 'invent' something new. But they don't understand how hard it can be. LTT does an amazing job recounting all the things that make product development hard.
This is a reaction to his video. I analyze his video and break down some parts and go off into plastic tangents. I hope it adds value to you and the development journey you might be on.
To be clear, I am adding analysis to his original video, and do not feel it overlaps any copyright infringement guidelines.

I found your channel because Jeff Geerling mentioned this video recently. I'm loving it so far!
same i came straight from there too
Searched for this video while watching Jeff

You were correct about the Delrin plastic that is used to hold the bits and its high stiffness that could pose a issue if dropped . JayzTwoCents did a review on the screwdriver where he dropped from his eye level and one of the tabs did break.
Tbf, he dropped it from about a foot above the top of his head, so a little over 7foot of a drop... but yeah, one of the bit tabs did break
He's the only one. There's this dude who mods cars for drifting in Tokyo and he dropped it from an entire floor and nothing happened.
Well, he's sold 97k of them so far at $70 a pop ($6.9+ mil) so... I think he made his investment back... lol.. According to Twitter, it looks like they're working on a mini-driver (stubby version) now as well. If you've never handled one, IMO it is a very good (albeit somewhat expensive) product. The handle feels good in the hand, the ratcheting mechanism feels excellent and behaves admirably in use and the knurling provides a solid experience either in use or as a fidget toy.. probably the last full sized screwdriver I'll ever buy...

Came here from Jeff Geerling. I've owned the LTT driver for a couple months now, used on many projects. I also have Wiha, milwaukee, craftsman, harbor freight, and snap on screw drivers and ratcheting drivers. I bought the LTT because I know how long they worked on it/the attention to detail but really thought of it as a educated gamble, but am very happy to say it's my favorite now. It fixed several issues, like milwaukee's atrocious front end weight that literally causes the driver to fall out of you hand when one handing. The ratchet mechanism is easily the best, and I pay attention to this though on my ratchets eg 90-110 tooth is best. Finally I have a ratchet driver where the selector is intuitive, left is loose, right is tight, small detail that matters. The biggest difference i've noticed is one handing performance, its light, the triangular shape is just right for my hand, and the endcap is large enough and free spinning so its very easy to spin with one hand and a claw grip. Only cons for me: stock bit loadout is not even close to ideal, I dont use square bits at all, and need more hex and torx. That's the only con for me personally so it's money well spent, and the overall feel has me reaching for it constantly. I'll buy another for work and I just learned of a possible stubby version I'll keep an eye out for. Well done and well made product worth the cost, especially versus milwaukee. I was so sorely disappointed in theirs, from a company that generally manufactures the best stuff, sigh
@@htr5372 you sound fun at parties lol. I work a lot and don't have time to spend analyzing the whole market before stating an opinion, I made a comment with my opinion after using it for some time and falling in love with it. I don't own any of those other ones you mentioned, I only used examples of what I've actually used, but clearly you have the time to analyze the screwdriver market in granular detail so I would defer to someone like you's opinion, if you didn't come off like an elitest snob. I didnt say i was comparing it only to ratcheting drivers, i was comparing it to wihas non ratcheting type because for one handing performance it doesn't matter to me if its ratcheting or not. Fwiw the backdrag and ratchet mechanism performance is so good I would consider anything better really splitting hairs, adding to your image of elitism. I have no doubt you know much more about this than me, maybe I was too strongly opinioned toward ltt driver in my comment and came off as such, but I had a few minutes to make a comment here after watching geerlings video so I just wrote what came to mind. Good luck with your channel, you should probably take a 2000 grit approach to comments vs 200 grit though, works wonders for credibility and respect 😉
@@htr5372 maybe that was too strongly worded so I'm sorry for that. Long day for me away from home fighting with machines. Cheers
I read the description: LTT are pretty chill with reaction content and only take down direct reuploads. CZcamss automated content ID system does sometimes cause issues though.
There's a vid on LMG clips about this.
I just found the time to watch the video. I have learned a lot and I like your way of presenting. I'll definitely check out your other videos - 3d printing has sparked an interest in plastics for me ^^ . (Being an engineer doesn't harm either, lol).
And you made me realize how big of a difference texture can make. It's one of those things that sound obvious in hindsight while being invisible until someone points them out.
Very informative. As a total noob in production, this was fascinating to me
found this video linked in soem other review that popped up in my feed, I'm glad I clicked the link. love the nerd talk and your insight into the industry
Its pretty funny in hindsight. Because the bit holders have been causing some people problem of breaking.
Interesting one of the other creators, i think it was Jayz 2 cents did drop the screwdriver and one of the delrin bit holders did snap. So that might confirm what you said about the "high stiffness" issue with delrin. However, they have done their own drop tests without issue, so it might have been a fluke.
From memory the issue was a failure caused by manufacturing breaking their fix for the issue
Very good video, well explained the process of product development. If you have connections that are willing, consider guests that are from different areas in the field. i.e tool designer, materials engineer.
It does make sense to use virgin material and not recycled at SOP/launch. Until PV tests have been completed with parts made from recycled resin would be risky.
Is the linus video on 1.5x speed?
Would be cool to see you dive into the datasheets of these plastics and analyze their actual characteristics compared to their markting terms like 'high stiffness' that don't mean much.
... what? He's a product development guy, not a materials specialist. Why would he have any particular insights beyond "X is good for injection molding" or "Y is better than Z when it comes to chemical resistance", or what he literally said?
41:15. I work in plastic extrusion and injection molding. You severely underestimate the power of TiO2. It overpowers just about everything, including carbon black. In fact, almost all light shades of colorant are part TiO2. It's not just that the fully saturated colorants have a lot of the pigment and the lighter ones less pigment. The main reason is that the pigment is being overpowered by the titanium dioxide, making the colorant "whiter". So, in fact, most black plastics CAN be recycled into a white product! And it usually requires less colorant than recycling a bright white plastic into a dark product.
Triax 1120 is an alloy of nylon and ABS. Nylon, even though it is a brand name, is used as a trade name for polyamides in general - which is actually a category of polymers. So I found it funny when you started comparing ABS to glass-filled nylon.
I have worked for more than 15 years with plastic injection as a mechanical design engineer, never heard of a mold of this size and complexity (pretty simple molds in this screwdriver) that cost 100K USD, not even close. From what I saw he should have 3 molds, lets say 4 cavities each, all of them together should cost no more than 100K for molds with a 500K-1M cycles lifetime (and this is an estimate on the expensive part of the spectrum you can get it lower), I guess he has 1 metal mold too which should be around the same price of 1 plastic mold and some machining for the other ratcheting mechanism parts. Most of the costs goes to the R&D process. Design of a product like this should take around 1 year from start to finish, so I guess the 3 years process is what cost him so much.
It’s 2 am and I have no idea why I found this interesting.
Great video!
I think Einstein said problems dont happen on paper
At a guess, he probably needs the elasticity of a stiffer material so that the bit retention doesn't deform and become loose and potentially not be able to hold on to the bits.
hearing about all these companies coming back to the usa and such makes me happy
maybe have a grease burger, shoot your gun and start a war to celebrate. USA USA USA
@@-opus weird comment, almost passive agressive?
@@jaxrammus9165 nothing even slightly passive about it
What the hell are you talking about? It's a Canadian company that used a Canadian company and an Asian company for production. Where in the hell did you get America from?
Nice overview. Making physical stuff sure is an expensive process.
100 000 canadian roupies for a cnc'ed aluminium mold ? Here goes the rippoff
So glass filled nylon/abs is becoming standard for higher end tools but it wears outs dies quickly
Not necessarily. Glass glass or carbon fiber-filled nylon is used a lot because it's damn near bulletproof but also slightly ductile. But other plastics like polycarbonate, delrin, PEEK, etc and composites with fancy additives are also very popular.
Great vid!
Nice video. Did you end up buying a screwdriver?
how come he doesn't know Delrin? POM is one of the most common polymers because it's so easy to machine or injection mould and is also used in low friction applications alongside polyamides. Every second 3d printing tinkerer knows it..
My professor talked like 15 minutes about it in the first lecture of material science.
Sorry if I'm being rude but this kinda undermines the rest of the video.
He's a film maker. Not an engineer
Because like he literally said in the video, it said delran not POM.
@@blackfire1088What about "product development specialist" is confusing to you?
POM is one of the excellent engineering plastics. Virtually all (not-horrible) plastic gears are POM. OTOH, ABS is the hallmark of cheap plastic tools, coming from the distant offshore.
A little disappointed by ho2 surface-level your entire analysis is. I expected a lot more from a video by someone in the industry.
... He gave insights on injection molding and the product development process every time it made sense. What the hell else were you expecting?

Plastic phantastic
Its a great screwdriver but those proprietary short bits are its biggest downfall.
It's such a minor complaint since if you want to use long bits you can just rotate that little ninja star and put in six normal bits.
@@TheSolongsidekick It's not a minor complaint. Even if you put 6 normal bits, the magnet is too weak for the longer bits. I actually have this screwdriver
@@TheSolongsidekick it's not a minor complaint, if you get your bits chipped/worn, you are less likely to replace them as it's very inconvenient... I can't source them locally and no way I'd order them from the other side of the pond.
Another complaint is that if the screwdriver is intended for 10Nm, I'd have likely a 1/4 drive or at least an open wrench one (but that would require a hardened steel shaft)
The screw driver is 70$ not 100$
No, it's $69.99 USD.
(The dollar sign goes ahead of the number in US currency.)
No it’s 100 CAD if you are in Canada like the maker of the video. Maybe you missed that point.
It’s only $70.00 US if you are in the US.
It's a lazertool screwdriver. It's a £20 screwdriver
No, it literally isn't. Not even close. If you can't identify the difference between a quality tool and a cheap harbor freight special you either haven't done a single day of work in your life or are just monumentally stùpīd. 🤡
And just because "uR jUsT oBsEsSeD" is the go-to for just about every dingleberry saying dumb shit online, I do not own the LTT screwdriver and only rarely watch their videos.
The fact that the LTT video was playing at like 1.25 or even 1.5% speed was so annoying ngl. if I want it faster I can speed up this video my self but if I don't want it faster I have to choose between there video being faster or this video being slowed down
Meanwhile Im super happy its sped up, I've already seen the ltt video and Im guessing a lot others, so spending extra time to see/listen again is just unnecessary
out of topics.. why is your lips so white? 😅
maybe my screen color off
my fill light settings were off, and I couldn't fix it in post haha

This is a rebranded slightly modified Megapro screwdriver that is selling well, even at this price due to marketing/fanboys. It is not even particularly well suited to pc building, due to its short shaft, and chunky handle, even though that is what it is primarily marketed for.
It's not a rebranded slightly modified Megapro screwdriver.
They only used there ratchet mechanism and even that got tuned, the rest is completely different.
Also I had never any problems with the length and the handle thickness for building PC's, it's fine to use. I even like the handle thickness, to thin and you don't get enough torque when something is screwed in tight. I have a bunch of screwdrivers non the less most of the time I grab the LTT one. It's just nice to use.
@@GermanMythbuster You hardly need any torque to work on pc's, the screws are tiny, a #2 phillips, ideally with a long shaft is perfect for nearly everything, unless you are ridiculously weak, or have arthritis etc.
It is a Megapro screwdriver: "A not so little secret about Megapro is that we also offer Custom Screwdrivers through Original Equipment Manufacturing (OEM) projects, like this one launched August 2022 with Linus Tech Tips."
Companies love brand fans $$$
@@-opus did you actually watch the video though ☠
@@codexous I watched the video 🦵 and I too can use an irrelevant emoti
Saying it's a rebranded and slightly modified Megapro screwdriver is dismissive and fundamentally incorrect. They started off with the Megapro Automotive, threw out every part of it but the ratcheting mechanism, the bit holder and end cap mechanism, and designed their own stuff. Even then they modified and tweaked those Megapro original elements. So basically almost no part of the final screwdriver is identical to Megapro's.
I'm not a fan boy, I have no horse in the race, I don't own one, and I don't want one. You can argue that the price is steep, and I agree. You can say you don't think it fits certain use cases, and ultimately that's often down to personal experience and technique, so it's fair to say it doesn't work for you. Saying it's basically the same as an existing product, when they've shown every single step they've taken that makes it different, makes you just look like you have no valid points and you just want to shit on it due to some sort of bias or cynicism etc.
How does somebody who supposedly deals with this as a profession not know the difference between stiffness and brittleness, or the fact that a design's stiffness is massively affected and determined by the shape of the item?
