ABSTRACT:
A test block and method of testing for law enforcement personnel to quickly and easily test the strength of and gauge the dimensions of a handcuff key before it is used in actual handcuffs. The block has an opening in its center which receives the latch tab end of the key and also serves as a gauge for the maximum permissible dimensions of a handcuff key. To test the key, the officer inserts the latch tab end in the opening and exerts pressure on the key with his thumb while holding the block in a stable position. The test block has a thickness which is sufficient to hold the key in the test block as it is being tested.
