Overview

The Klein 2100-5 is a single-piece cutter made from alloy steel, including the handle, weighing 3.2 ounces with a listed length of 1.88 inches.

At just over 3 ounces, this sits among Klein's lighter hand tools. The 1.88 inch figure in the listing is short for an overall tool length, so it may describe a jaw or cutting head dimension rather than the full tool, and the listing does not clarify which.
