English Explanation 

A snake, dead or alive, is always frightening. In normal circumstances, nobody would like to touch or handle a snake for any purpose. With the Shona elders, a brave person was meant to show his bravery by measuring the length of a dead snake without using a stick or a string. The proverb implies that a man should not hesitate to state facts, even if it means to accuse a person of higher status. ‘Call a spade a spade.’ Also, do not substitute false imitations for the real thing.
