Review title: Plan on squaring it before use!
Product review: I have had experience with two of these and both were less than square out of the box. This meant they were not on the same plane as the stone's top edge and sharpend planes and chisles at a slant. I fixed mine by placing it in a bench vise and pulling on the arm until square as measured with a large carpenter square. This solved the problem.
