Precision Wheel Mortice Marking Gauge - Metric & Imperial

"Bad buy. The cutting wheels were blunt and would have difficulty is cutting through melted butter. They are slopping on the shaft, so even if you do manage to lock them in the right place, which is extremely fiddly, they wobble and give a very uneven line. Difficult to adjust accurately. Now in my box of 'bad internet buys', heading for the charity shop. Dusted off my old rosewood and brass mortise gauge and getting good results."
