What is a 'sling blade' or 'Kayser blade' used for?

Answer 1

A sling blade was used to cut tall grass and weeds before the modern machinery was invented. The Kayser blade has a long handle and a person can use it to cut weeds and etc. on banks and hard to reach places.

AnswerIs the sling blade and the Kayser blade colloquial names for the sickle and the scythe? AnswerI always heard them called sling blades growing up in Alabama but I often see them sold in hardware stores as "weed cutters". Answerit is also called a ditch bank blade. Without the wooden handle as used by the "highway boys"...it's more of a scythe.
