When using a Wasp, treat the tool as you would a sharp pencil. Pressing down too hard when angled is likely to break the tip of the tool.
When cutting with a Shark or Barracuda be sure to angle the tool slightly towards the template edges to maintain a crisp cut line in your final work.
Your body weight is usually sufficient to hold the template in position while you are engraving. But be sure to stand or kneel close to the area you are engraving to limit template lift.
For vertical cutting, mount templates using concrete anchoring screws. Failure to maintain continuous movement of a kaleidocrete tool will result in unsightly deviations in cutting depth.
