As others have said, my first paddle was a hacksaw blade but take care of
the sharp points!
Better is a strip of pcb material, or 2 strips with a separator for iambic.
From memory I used about 5mm wide and about 40mm from the fulcrum, which can
be just a wood block with 2 slots cut and a screw through to pinch together.
If you start to get ambitious, you could make the whole keyer/oscillator on
the pcb, perhaps a TIC keyer.
I did this to fit inside the base of a Norcal 20 with the paddle sticking
out of the side to which I screwed a pair of Kent paddle handles. You could
just shape the pcbs into large finger pads.

Subject: [Elecraft] simple iambic paddle
Knowing the penchant for CW that many of you have, I thought I would ask
the following question here.
Does anyone have a design for a very simple iambic key that can be made
with simple materials and hand tools? The kids are starting to send CW
and I am finding they are having a LOT of trouble with a straight key.
Most immediately gravitate to the bencher so I am trying to find a way to
make a $5 paddle.
