Cost!  Why spend money when you don't have to!  The idea behind tile tools
is to drop the cost of making a mirror by replacing the expensive piece of
glass to be used as a tool with plaster and tile and a cheap piece of metal
for digging the basic hole that ends up being less than 10% of the cost of
that glass.
