Metal And Black Diamond Markers On Measuring Tape
The metal end is also used for a variety of functions. If no one is around to carry the measuring tape’s other end, a small slot can be wrapped around a nail to keep it in place. It’s also worth mentioning that the edge is serrated slightly. If you can’t find the pencil concealed under your ear to chart your measurement, you can easily mark a wall or other surface.
Holes in Padlock
The lock relies on these holes to perform two important functions. To begin with, they allow any water that enters the lock to drain out. Since locks are often used indoors, they must be weather-resistant. Since water expands when it freezes, the lock will be severely damaged if the water couldn’t drain and froze. Second, the holes allow you to pour oil or WD-40 into the lock if it becomes stuck and refuses to open. The lock would be useless if it didn’t have a hole for pouring gasoline if it got stuck.
