But Klein D2000-28 remains excellent—especially if you value American-made tools, prefer the grip profile, or want to save $5 per pair. Many veteran electricians swear by their Klein diagonals and see no reason to switch.

The honest answer from the trade forums: both are professional-grade tools that will serve you well. The difference comes down to hand feel and brand preference.

Klein D2000-28 Overview

The Klein D2000-28 represents Klein's heavy-duty diagonal cutting line. Made in the USA from custom tool steel, these are the cutters you'll see in half the electricians' pouches on any commercial job site.

Why Techs Choose Klein

The 36% leverage advantage is real. Klein positions the rivet closer to the cutting edge than standard diagonal cutters, and you can feel the difference when cutting through #10 solid copper or snipping tie wraps all day. The short jaws and beveled cutting edges let you get flush cuts against surfaces—useful when trimming cable ties in a crowded panel.

One electrician with 38 years in the trade put it simply: "One cannot go wrong with these." After decades of daily use, his Klein tools still perform. That's the kind of longevity that justifies the investment.

Klein's induction-hardened cutting knives handle ACSR, screws, nails, and most hardened wire without rolling the edge. When you're cutting hanger wire or trimming self-tapping screws that missed the stud, you need cutters that won't flinch.

Knipex 74 21 200 Overview

The Knipex 74 21 200 brings German engineering to the diagonal cutter market. At just $5 more than the Klein, it offers precision cutting edges hardened to approximately 64 HRC—capable of cutting piano wire without dulling.

Why Techs Choose Knipex

The weight difference is noticeable. Users consistently report that Knipex cutters feel "so lightweight in your hands compared to Kleins"—and after a full day of trimming cable and cutting zip ties, that weight savings translates to less hand fatigue. The 12-degree head angle provides hand clearance in tight spaces, letting you cut flush against panels without smashing your knuckles.

What sets Knipex apart is the cutting action. One tech described it as "they cut wire like butter." Coming from other brands, "they feel so much better in my hand and cut amazing." The precision-ground edges maintain their sharpness longer than competitors, and the chrome vanadium steel takes abuse without chipping—assuming you're not twisting the cutters while cutting.

The multi-component grips are a subtle but meaningful upgrade. They're essentially bonded to the handles rather than just dipped on, which means they won't slide off or wear through as quickly. For all-day use, grip quality matters more than most people realize.

Head-to-Head: Cutting Performance

Both cutters handle standard low voltage work with ease—Cat6 cable, 18-gauge thermostat wire, zip ties, and 14/2 Romex pose no challenge to either tool.

Where differences emerge:

• Hardened wire: Knipex's 64 HRC edges handle piano wire; Klein's induction-hardened edges handle hardened wire but aren't rated for piano wire specifically
• Flush cutting: Klein's beveled edges excel at close cuts; Knipex's 12° angle provides better hand clearance for flush work
• Heavy use: Knipex's lighter weight reduces fatigue on high-volume days; Klein's mass provides momentum on tough cuts

One honest take from the forums: "It cuts just the same as my Klein's." For most low voltage applications, you won't notice a performance difference in the actual cutting. The differences show up in hand feel, weight, and long-term edge retention.

Head-to-Head: Durability

This is where the debate gets heated.

Knipex's reputation: Multiple users report that after a year of daily use, their Knipex cutters "still looked brand new on the cutting edges" while their previous Kleins were "pretty much shot." The higher hardness (64 HRC) means better edge retention—but also means the edge can chip if you twist while cutting.

Klein's reputation: The hot-riveted joint ensures no handle wobble over time—a common failure point on cheaper cutters. The softer (but still hardened) steel is "tough but softer," meaning it won't chip as easily but may need sharpening or replacement sooner.

The trade-off: Knipex stays sharper longer but requires proper technique. Klein is more forgiving of "horsing around" but may dull faster.

Head-to-Head: Ergonomics

Klein D2000-28: The grip length and width is "near perfect" according to many electricians. The plastic-dipped handles provide adequate cushioning and make the tool easy to identify in a crowded pouch. Some find the overall weight helps with momentum on tough cuts.

Knipex 74 21 200: Lighter overall weight means less fatigue on high-volume days. The bonded multi-component grips are considered "the best available"—they won't slip off the handles like dipped grips sometimes do. The 12-degree angle keeps your hand away from surfaces when cutting flush.

One criticism of Knipex: the tip is "very round and not as pointed as the Kleins." If you're frequently working in tight corners where a pointed tip helps, this could matter.

Frequently Asked Questions

Can diagonal cutters damage low voltage cable performance?

For most applications, no. Diagonal cutters can deform the cut end of coaxial cable, but since you're trimming that end off before termination anyway, it doesn't affect post-termination performance. For cleaner coax cuts, consider dedicated cable cutters with concave jaws.

Why do some electricians say Knipex is better for cutting but Klein is better for other tools?

Different tool categories have different design priorities. Knipex has invested heavily in precision cutting edges and leverage geometry, making their pliers and cutters exceptional. Klein's strength is in screwdriver tips, handle ergonomics, and the breadth of their product line. Many professionals mix brands to get the best tool for each job.

Will the 64 HRC Knipex edges chip easily?

Only if you twist while cutting—a common bad habit. The harder steel holds an edge longer but is more brittle under lateral stress. Use proper cutting technique (straight compression, no twisting) and the edges will outlast softer alternatives significantly.

Are Klein tools still made in the USA?

The D2000 series diagonal cutters are made in the USA from US-sourced tool steel. However, not all Klein products are American-made—check individual product listings. The "Made in USA" designation is a selling point Klein emphasizes on qualifying products.
