Excellent work showing how the OTF works, thank you.

Oh my gosh, my daughter bought herself an expensive switchblade at the mall that she’s in love with. I’ve never had one and was playing around with it and it stopped working. I thought I broke it and she was going to be so upset with me and I’d have to pay to get it fixed. Then I thought maybe if I watch a video on how they work I can take it apart and fix it myself. So I was watching this and figured it out. I pulled the blade out all the way and the mechanism snapped back into place. Now it’s working fine, I didn’t need to take it apart. I feel like an idiot, but oh the relief and now I know how these things work. Thank you! I’m going look like a genius when she inevitably does the same thing and thinks she broke it, just to have me take it and fix it no problem. Lol

This vid is by far the best OTF teardown and demo of function which I’ve seen on YT. I’ve owned a few OTF’s and have already disassembled, cleaned, reassembled, so I understand the machine. However, I can’t currently take my Delta apart, (because proprietary hardware), so I really appreciate your choice of that particular model here! 🤠👍

Dude, AWESOME video!!!! You did such a great job explaining exactly how these work in great, simple detail. I just got an TacKnives DA OTF knife a few weeks ago, and while playing with it I was really curious as to how these worked. The idea that the same switch could deploy the knife and also retract it with force really had me stumped until your video. Thanks again!

Masterfully explained and more importantly.....SHOWN. Thank you.

beautiful video. Appreciate all the extra efforts made to illustrate the actions of the separate parts. Very useful info. Please keep making clear concise vids like this. We need more.

It is amazing how something I used to think was so complex actually is kinda simple

Excellent! Thanks for showing exactly how it works. I appreciate that you took your time to explain parts individually. I have seen other videos when it’s like a game show where the person in the speeding through and it seems like a test to see how fast he can disassemble and reassemble. Very informative.

You have my thanks for demystifying the operation of the double-action OTF. I have a few of them, but have been too intimidated to open them up before now. Thanks again!

Great explanation. Engineering marvel

Loved this breakdown, great stuff

Nicely explained. Always wanted to know how it works. Thanks!

Great video man, very informative. I just ordered this same knife and I know there's no way I'll be able to rely on Microtech's customer service alone, so it's good to see what I'll be getting into if/when I need to repair it.

Excellent video, thanks!

Thank you very much. Very useful knowledge. I was wondring how it works.

Excellent video. Sort of like a short stroke gas piston system works on an automatic firearm.

Awesome! I always wondered how these worked! Great explanation and video

Cool well presented. Thanks. 🇬🇧👍 I guess without the round stop, the blade would shoot out?

Good video.... if you had shown the the mechanism with the spring on, it would have been even better.

About 5:00 I've got it in my mind XD

It works by something called inertia

👍👉👍👍👍👍

Hope you took pictures

Isn't it kinda funny how much people pay for such a simple machine? You can buy one of these made of cheap materials for $8. Are the materials they use for brands such as microtech really worth spending up to $1000? Or, are we just paying for a brand name? I have a microtech that was around $500, but I don't use it. I also have an Atomic Defender OTF that was $35 and works just as well. I have cut Manny Manny boxes with my cheap otf and it has never misfired. I do have to sharpen it every once in a while, but I enjoy that. Thoughts?
