Overview
Klein lists the 100CS as a carbon steel cutting tool with a metal handle, coming in at 2.9 ounces and 1.88 inches as a single piece. It has picked up a 4.4 star rating across 371 reviews.
Klein Tools has a long track record with electricians and tradespeople, and the carbon steel build fits that reputation for durable cutting tools. The 1.88 inch figure in the listing is not labeled as overall length, jaw length, or blade length, so it should be checked against the product photos rather than assumed. At 2.9 ounces it is light enough for one-handed cutting tasks.

Performance notes
Carbon steel construction is standard for cutting tools that need to hold an edge under repeated use, and a metal handle adds durability over plastic. At 2.9 ounces the tool is light enough for extended one-handed cutting work, though the listed 1.88 inch measurement is not identified clearly enough to judge reach or capacity.
