For Frame-saw Nuts Only

Jeff Burks of 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.

    Ah, I didn’t know Chris was going to blog about this one! This is one of those unfinished and unedited files that I don’t show anybody because they are such a mess. Oh well I guess this is a good reminder that I should stop goofing off and finish it.

    BTW Chris, are you suggesting that you just toss your used coping saw blades without attempting to sharpen them at least 5 or 6 times? I’m shocked!
