Everybody needs a leather punch. Don’t leave your shop without having one there. And if you need leather, like from a belt, try a thrift store. Usually a buck.
The other three tools are for sheet metal work. I don’t know what they’re called, but the last one is a clever notching tool. I have used all three when I’ve had to add to or modify my dust collection ducting. They don’t lay well in a drawer, but when you need them, yeah, way cool. The middle one wrinkles ducting to reduce its diameter so it’ll become a male to a stock end which becomes female.
The orange straight edges are so much easier to find on the workbench than the clear ones. I couldn’t pass these up. I think they were 25 cents apiece.
There is nothing special about the 12 inch ruler except it is such high quality. Stainless, no doubt, from the L.A. Spievak Corp. in L.A. No. 731. “Calibrated in USA by Spievak” it says. Four scales, eights to 64ths, and it cleaned up beautifully with some steel wool. It’s hefty—.042 thick.
The feeler gauge is in pristine shape and must be USA. The little 6” depth gauge is a General brand. I salute it.
I saved the best for last. The 6” rule with the curved end is from the Zimmer Mfg. Co, Warsaw Indiana. Patent pending, made in USA. On the back it has a set of drill size/screw size pairs of holes, then three holes for different Kirschner wires, and seven holes for Steinman Pin and twist drill sizes. This had me flummoxed for years but recently I stumbled upon its application: surgery. Yep. It’s a medical ruler. For Orthopods. No doubt Dr. Canty had one. He was Evel Knievel’s surgeon. My mother was Dr. Canty’s Office Manager for years.
Oh, the blue thing. Need to know the diameter of something? Slip it into the loop and pull the slider snug and read the number in inches or mm. It’s the QuikSizer from Solution Engineering. It has a dotcom address so it ain’t old, but it’s clever and I own it and I’ve never used it but one of these days…
