This 12" long overall end nipper pliers are in very good condition with removable cutter insert. They are marked "TODD'S MADE IN U.S.A." in small lettering on one side near the pivot pin area. Todd had the patent on this interchangeable cutters nipper type pliers in 1876, but it is not known what company made them, or for how long. This is a tool that is not made any more today, yet is still useful to contractors who work with heavy wire such as in concrete work. I cut wire 1/8" thick with these nippers with no harm done to the cutters at all! The adjustable stop keeps the cutters from hitting together when the wire is snipped, thereby prolonging the cutter life. These will open up to 1/4" between cutters! A great tool design, in great working condition! Cutters are in good condition, good cutting edge, and alignment, not perfect, but cuts nicely.  We have not seen this size Todd's nipper with the handle ln the curved out bend at the end of the handles, but it is actually more comfortable to use that way.  Some minor pitting noted. not on the cutters but on the rest of the tool it appears, makes no difference in the performance of this tool.  It is not rusty at all now, and still cuts good. These cutters work very well on heavy wire, but not made for piano or instrument type wire. A very nice nipper, clean, no rust, with a good snug pivot joint, they work just fine. Hard to find in useable  shape like this one!
Very well designed antique tool!
