DIY Secret wooden padlocks (option 2) After the previous video, many subscribers noted: "Very easy to open with L-shaped wire". And I created a response video of animation (changed the design of the locks), which is impossible to open with L-shaped wire. Note: The holes for the lock are not cut like this, they are just regular vertical holes. When you insert the key into the lock, after the first tooth passes, the key turns a certain degree and is pushed further. #lock #latch #padlock #simpleide
