Prepare for proper prying
I use a lot of templates and specialized fences for box-making, all of them secured with double-faced tape. I used to pry them up with a putty knife or chisel, until hitting upon a better idea. Now, I rout a small shallow recess or two along an edge of the fence or template for easy prying with a screwdriver. Just be careful not to damage any workpiece surfaces—it helps to use the screwdriver handle as a fulcrum instead of the screwdriver tip. Or place a thin wooden pad at the fulcrum point to provide protection.
