For what it's worth, I used to be a weldor (not a mis-spelling -- this
refers to the person doing the welding!).
I had some Williams wire cutters ("diagonals" or "dykes") that I bought in
California at a store called Orchard Supply Hardware. Now it's called OSH.
I absolutely loved these wire cutters. The design provided a lot of leverage,
compared to many other wire cutters I had owned. It made it relatively easy
to cut some pretty thick welding rod, wire, etc. I ground the jaws down so
they would more easily fit into the nozzle of my mig welder (this is the spelling
for the machine!), for despattering purposes. It was a great couple decades
of welding for a living.
