The design is simple with positive locking in both open and closed positions. It’s safe to use and very strong. How to assemble: Insert an SK5 blade as seen bellow, you might need to use a little force until it snaps into place (you can buy them by seaching “trapezoidal blade” on temu, aliexpress, amazon, etc):    2. Then push it into the main body like this: Tip: At first, the blade may feel a bit stiff, which is intentional. This stiffness is to prevent accidental opening, especially while in your pocket. With continued use, the mechanism will become smoother.If you find it too stiff for your preference and have silicone lubricant or another plastic-friendly lubricant available, you can apply it to the sliding mechanism using a q-tip. This will make the action butter-smooth while ensuring secure locking.
