Review on Black Safety Padlock for 🔒 Lockout Tagout – Master Lock 410BLK by David Weis

I tore up this padlock to see what it is made of and was surprised at what I found. The shackle is ball bearing mounted and the core is pierced with serrated and coiled safety pins. In other words, only an experienced locksmith/fitter can open it non-destructively. As for physical strength, the bonds are quite strong. The body is fairly stiff for toughened plastic. I drove the chisel into the body for a few minutes before I managed to break the body. Definitely a strong padlock.
