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.
- Alloy steel construction
- 3.2 ounce weight
- 1.88 inch listed length
- Sold as 1 piece
Who it's for
Fits electricians and technicians who want a compact, lightweight cutter for tight spaces. Less suited to jobs needing a long-handled cutter for extra leverage.
Strengths and trade-offs
Drawn from this product's published specifications.
- Lightweight at 3.2 ounces
- Alloy steel handle and body for durability
- Listed 1.88 inch length is unclear whether it covers the whole tool or just a part
Performance notes
Alloy steel construction throughout, including the handle, gives it durability without much added weight, staying at 3.2 ounces. Its compact size suits detail work in confined spaces over heavy-duty cutting.
