Abstract
A stepwise and stepless adjustable square for use in carpentry, including: a stock; a blade; a first alignment structure; a second alignment structure; a spring device; a spring expansion-restricting element; and a knob movable between a first position and a second position, wherein in the first position the first and second alignment structures at certain angles between the stock and the blade align and engage such that a force of the spring device is reduced compared to the force at angles where the first and second alignment structures do not align for stepwise adjustment, and wherein in the second position the first alignment structure is moved axially away from the second alignment structure for stepless adjustment.
