Ko-ken Free-Turn Wrenches 

Put a reducer adaptor and you've got a 3/8 drive, ready to go 😁

Exactly! Not annoy your apartment neighbours and reduce the chance of strata banning you from working on your car.

Hi Doug. Double locking? Care to share a link? I may at some point do a tool box tour video if the urge strikes me. I have a feeling I'll just ramble on forever on one drawer for 20mins! Yup, I know that channel. I was there a few days ago. I just happened to come across a video he recently did on his Nepros haul, and yeah, he does have a good voice! Thanks!

Another commenter below, Peter Griffin, mentioned about Deen tools having one in 1/4" drive. This is a quick video featuring their latest design (now a 2-peice design): ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kcWiywvFJdY.html

You won't regret your decision!! Go for it! 😁

Yeah, in a pinch, the 3/8 T-handle would work as an extension, but I wouldn't use it with say a 18" long breaker bar/ratchet trying to break free a stubborn fastener.

@@chriscas-ToolAficionado Yeah, I probably wouldn't either. But I could see it in that situation where you have a super long and crazy extension setup with a u joint trying to get something deep in an engine bay. You can use the collar to help stabilize the extension setup to reduce the wobbles with the u joint. I use a 1/4 cordless impact alot so I don't think I would worry too much about it. Not that I would buy it just for that, but as secondary use and another tool to add to your arsenal. Thanks for these awesome videos by the way. Going through alot of your video catalog looking for interesting tools to increase my productivity. I REALLY like the ko-ken stubby 3/8 with the 2 drive spots on it, might have to try that out. So many potential uses for it. I also commented on the twist ratchet video you have and I might try out the US PRO version of that to see how it is. My favorite power tool brand doesn't have a very good cordless ratchet, so that might be a good replacement instead of having to invest in a whole new tool line.

​@@Pauleh123 Snap-on has one of those multi-purpose ratchets as well in 3/8 drive, and it's a Dual-80. Nepros is another one, but the square is only on the top/bottom (not on the end, like the Ko-ken and Snap-on do). Cordless ratchets are a complete game-changer. I also like using Tite-Reach/Ratchet extension tools as well. Awesome additions to your tool aresenal.

@@chriscas-ToolAficionado Tite Reach added to my wish list! I looked up the Snap-on version and their online catalog doesn't have a photo and has the wrong PN. It's titled there as a dual 80, but with only 36 teeth. Found a scanned catalog and found the correct PN to be FZ936A. Still titled as a dual 80 ratchet, but still described as only 36 teeth with a 10° swing arc! I found that 2 3/8 ratchets on their catalog are listed as dual 80, but have less then 80 teeth. Very confusing. 36 tooth is certainly am improvement over 24 tooth, so I think I will pick one of those up. It seems my idea of the perfect do it all 3/8 stubby doesn't exist quite yet. The Nepros looks awesome, but now that I've seen the 3 position ones I can't get it out of my head. Maybe I'll pick one up if I find the Snap-on frustrating enough.

@@Pauleh123 Just a heads-up on the Tite Reach stuff. I have their 1/4 drive "Professional" one. Despite the professional name, the build quality isn't quite up to snuff, IMO. It's still a very handy tool to have though, so I'll give them that. I have a old Blue-point chain drive wrench in 1/4 drive as well and that unit is built well. You may find it and other sizes in the used market. Mine is part # JWT1 . There's also larger, bulkier units that are impact rated. Those are offered by Snap-on, MAC/Facom/USAG. Merry is another manufacturer (Japanese) that makes their "Barrier Wrench". I could've sworn the one I handled in the Snap-on truck was a 80-tooth model, but I must've been dreaming. It's probably a matter of time before they update it.

Yeah, I'm surprised they haven't come out with one already!

Deen have one

You're right Peter. It recently evolved into a second generation where it became a two-piece design. This video shoes the first and second gen: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kcWiywvFJdY.html

SK Tools is probably the most economical source. Just search "sk tools locking adapter" Here's a link to one source for the SK www.toolsource.com/38-in-drive-c-194_252_562_701/38-in-drive-locking-socket-adapter-p-56747.html Shop around for better pricing!

Good eye. I don't have the tool in front of me, but if I recall correctly there is. You could if you had to, but be wary of overloading the joint if using it with, say a 18" breaker bar, and fighting a stubborn fastener.

I have a Tone version of this now, but I plan to get the Ko-Ken and KTC ones.

I also have a Flash Tool thing that is like a T handle with a removable bar.

It's an adapter that you can fit onto the end of any extension. There's a set screw that you tighten to get the adapter to fit firmly. I can't remember the name of the original US manufacturer, but they are/were sold by many brands, even by Stahlwille. There are copies as well. Here's a Snap-on/Bluepoint branded one: shop.snapon.com/product/Extensions-Locking-(Set-Screw)%2C-Chrome-(Blue-Point)/3-8%22-Drive-Locking-Set-Screw-Extension-(Blue-Point)/YA525A

Nice to hear that 👍 Back then I used to use it a lot more. Now a days, hardly ever.

That's a good question. I've yet to pin-point the US manufacturer of these adapters. They are sold under a few brands, including European brands like Stahlwille. In the US, you can find them from Snap-on, MAC, and SK. Cornwell and Matco might be offering them as well.

@@chriscas-ToolAficionado thank you so much

Hi! Nice to see a viewer from Indonesia! What Japanese brands are sold in Indonesia? KTC, TONE, ASAHI?

@@chriscas-ToolAficionado all three, and the others like vessel, eight tool, lobster ( most rivet gun), koken ( most just socket and impact driver), tohnichi, kanon, anex, engineer, toyo ( toolbox). like koken, kowa seiki hard to available here.

@@iyansuryana678 That's a pretty good selection! Do tool stores there (in Jakarta?) sell American and European tools as well?

@@chriscas-ToolAficionado Here named Glodok shops. There like Chinesetown, mostly chinese descent as sellers. but now it's easy through online shopping which famous in indonesia like tokopedia or bukalapak.
