Overview
Klein built the 21010-6-SEN around alloy steel throughout, jaws and handle alike, keeping the tool at a light 3.2 ounces for quick, one-handed wire and cable work.
Klein Tools built its name on electrician-grade hand tools, and this cutter carries the same alloy steel construction through both the jaws and the handle rather than adding a separate grip material. That all-metal build tends to favor durability over cushioned comfort during long sessions.
- Alloy steel jaws and handle
- 3.2 ounce weight for compact carry
- Sold as a single piece tool
- Rated 4.8 stars from Klein Tools buyers
Who it's for
Fits electricians and tradespeople who want a compact, all-steel cutter for wire and cable work. Less suited to anyone who prioritizes cushioned grips for extended use.
Strengths and trade-offs
Drawn from this product's published specifications.
- All alloy steel construction for durability
- Lightweight at 3.2 ounces for one-handed use
- From Klein Tools, an established electrician brand
- No cushioned grip material listed
- Not sized for heavy cable or thick stock
Performance notes
Both the jaws and handle are alloy steel, so the tool leans on solid metal construction rather than a separate rubberized grip for comfort. At 3.2 ounces it is light enough for one-handed use in tight spaces.
