I found one of these today (haven't taken picture yet), but found them on the web and they're usa made and still in business.   This looks just like the one i found and if you click the where to buy i'll tell you i paid a buck for it.   nice tool and if you ever do screen spline you know what i mean about having the right tool.   They make all kinds of stuff I didn't even know about.

forgot to add link DOH!

Had to use mine a few weeks ago...when I also trimmed the end off my left index finger.....Screen is installed.   

I have one, too. Got it at Lowe's

 

I've had mine so long I can't remember where i got it.  I've run across it from time to time and wonder how the pizza cutter got in the tool box.

Years ago there were lots of guys hanging wall paper for a living. That was their almost # 1 tool next to a long straight edge. I think there were a few of those guys on the fire dept in the sixties and one on my shift.
