This tool is awesome! It would save a lot of time!

It's more difficult that finding plain cards.

I just "invented" a device that should be quite easy to build from DIY store
parts. Do you understand the "schematic" . operation is as follows:

-a wood block with an indentation that holds a full card in place.
-two covers (wood blocks) with cutter blades that can be rotated so that the
blades cut the card with pressure.
I did not find a way to arrange four blades in a rectangle, so the cut can
be done in two steps. Two tools can be built, each one with a task, so that
one people makes the first cuts, while a second one can make the other cuts.
The result is a small rectangle, the edge can be cut easily with a third
step with a blade at 45° or with cissors.

Just my vapor-hardware for today...

Building ideas:

blades: (seems light
to cut a card with pressure only, but worth a try.)


These can be found everywhere I think.
