Jeff Burks of CarpentryArchive.org is
a patent-searching madman. And his insanity is your gain. He’s been
assembling patents on coping saws, Buhle saws, bow saws and their blades
and collecting them into a handy pdf that will delight and bewilder
See the Fenner patent saw (above). Marvel at the saw-filing
vise designed for coping saw blades (you read that right). And hoot at
the coping saw made from one piece of twisted wire.

It’s 229 pages long. And it’s a work in progress. More to come.
