Wehrs Machine WM484 Features:

This is our new Jason Sivils inspired adjustable sipe setter! This cool tool allows you to pre-set your siper depth flat or at an angle to add strength to the trailing sipe blocks. Inner block has lines 1/16 in. apart, or you can use a caliper to set depth. The inner block can be flipped to set blade depth on non-Van Alstine type siper heads and all grooving blades.
