No Sh*t. That stuff is nasty. I was given some masonry blades for my angle grinder, to carve with, and one of the teeth shot off at less than listed max RPM before it ever touched the stone. Hit my glasses at an angle. Without them I would have lost my focusing eye. Thank god for safety glasses.Originally Posted by Murray@uptowngallery
As for the levels I love my 2 dollar bulls eye level. Just drop it on top of the camera and level away. I splurged and bought two.
