I found a microtech OTF knife in bad shape and wanted to fix it. It was different than the knife in your video but your explanation was so thorough I was able to understand the fundamentals of this design. I was able to dismantle, clean and repair the knife. Thanks to you I have a cool EDC knife. Keep up the good work.

So basically the two springs (some OTF knives use only one spring) are under some stretch tension all the time. Moving the thumbswitch adds some more spring stretch tension and releases the little catcher tabs on either end and the blade slides either forward or backward. Pretty smart idea making a spring do work in either direction. I just wonder how much thrusting force an OTF knife can withstand before the blade collapses back into the handle. Seeing the guts of the OTF makes me think of a glorified utility knife for some reason. I guess it is like seeing the sausage being made. Great job on your video here.

Found a Benchmade OTF on the side of the road a while back, and I loved that thing. I basically used it as a glorified box opener, but it was extremely handy and I used it every day. Then it started getting stuck open. Took it apart, thoroughly cleaned it and hit it with dry lube. Still gets stuck out. Thought about buying a new one, then I saw the particular knife I have is like $400. I was hoping to glean some insight as to why it would close normally, but I'm still stumped.

06:02 That's one word is enough to explain the entire mechanism about how it works
(*anyway I'm a homemade knife too )

Applying years of gun smithing, race engine building and machine shop experienceâŚâŚ.it seems only logical that IF one was to mirror polish the contact surfaces on the plate and the detents, the âtrigger pull weightâ can be dramatically lessened on these which would provide a much lower amount of pressure necessary to be applied to the thumb switch in order to fire the knife! đ¤đ¤

Great video. Would love an explanation of how the blade stops if it encounters an obstacle / resistance while opening though. Thatâs an excellent safety feature of these OTF knives and always perplexing. Is it because it has forward momentum from the spring while opening but doesnât reach the detent to âlock it openâ so it just stops the momentum?

Iâve watched 6 videos on this subject today (how does an OTF knife work) but your video has the best explanation, thank you đđź
