I'm shopping for a new tape measure and would like to know what a thumb blade lock is?
A tape measure is designed to be a one-handed tool, with the exception of the blade which is pulled out of its storage case with the user's other hand. Activating the thumb blade lock after the blade is extended locks the blade in its existing open position. In the locked position, you shouldn't be able to pull the blade out any farther.
As you shop for a tape measure, check to see that you can comfortably reach and operate the thumb blade lock with your thumb as you hold the tape measure in the same hand. It's important that the case fit comfortably in one hand and allow easy reach and operation of the thumb blade lock.
If you are unable to lift the thumb blade lock back into the up position after it was in the down (locked) position, it's possible the factory has installed an incorrect thumb lock for the design of the case.
Typically the thumb blade lock is located somewhere in the middle to high end of the tape measure's case, but as you can see in the image to the right, thumb blade locks come in different styles and sizes.
