the.com/mortiser
The chisel that bores square holes because round ones were too easy.
means A tool or machine that cuts square or rectangular holes (mortises) into wood to receive a matching tenon joint.
from From "mortise," the joint itself, which came into English in the 14th century from Old French "mortaise" — a word of uncertain deeper origin, though it may trace back through medieval Latin or possibly Arabic. The "-er" is the plain English agent ending, the same one that turns "cut" into "cutter": the mortiser is simply the thing that makes the mortise.
