shears (n.)

"large scissors," Old English scearra (plural) "shears, scissors," from Proto-Germanic *sker- "to cut" (source also of Middle Dutch schaer, Old High German scara, German Schere), from PIE root *sker- (1) "to cut." In 17c., also "a device for raising the masts of ships" (1620s). As "scissors," OED labels it Scottish and dialectal. Chalk is no shears (1640s) was noted as a Scottish proverb expressing the gap between planning and doing.
