A cut-resistant glove rated "ANSI Cut Level A5" sounds like a definitive answer to a hand-protection question. It usually isn't. We've been making cut-resistant gloves at G & F Products since the 1980s, and the single most common mistake we see — from one-glove buyers and from procurement teams ordering by the pallet — is treating the ANSI letter as the whole spec.

This guide walks through what the ANSI/ISEA 105 cut levels actually measure, where the test conditions diverge from real work, and how we tell our customers to match a glove to a job. By the end, you should be able to look at a glove cuff stamped A5 and know whether that's overkill, underkill, or right.

What ANSI/ISEA 105 actually measures

The ANSI/ISEA 105 cut-resistance scale (revised 2016) runs from A1 (lightest) to A9 (highest). The number is the result of a single laboratory test: the TDM-100 machine drags a sharp blade across the glove material under a known load, and records the grams of force required to slice through. More grams = higher rating.

• A1: 200–499 grams
• A2: 500–999 grams
• A3: 1,000–1,499 grams
• A4: 1,500–2,199 grams
• A5: 2,200–2,999 grams
• A6: 3,000–3,999 grams
• A7: 4,000–4,999 grams
• A8: 5,000–5,999 grams
• A9: 6,000+ grams

That's the whole test. Notice what isn't measured: puncture resistance, abrasion resistance, tear strength, heat resistance, grip in oil or water. A glove can hit A6 for cut and still tear like paper if you snag it on a bolt thread. That's why we always pull all five EN 388 numbers off a glove cuff before we commit to a recommendation, not just the cut rating.

How we choose a cut level for a real job

In our R&D conversations with customers, we ask three questions before we suggest a level:

1. What is the cutting hazard? Sharp edges (sheet metal, glass) need higher cut. Slipping blade hazards (knives, utility blades during use) need cut and grip.
2. Is the hazard continuous or intermittent? A meat-processing line worker is in constant contact with a knife edge. A glazier handles glass for a few minutes between trips. The first needs A5+ all day; the second can sometimes use A4 with thicker cuff.
3. What's the work the glove also has to do? Cut protection often comes at the cost of dexterity. A surgeon's-grade fine task in A6 is miserable. A demolition crew in A2 is dangerously underprotected.

Here's the broad framework we use internally:

• A1–A2: General assembly, light material handling, packaging, small-parts work where cut is incidental
• A3–A4: Construction, light glass handling, automotive, HVAC trim work, light kitchen prep
• A5–A6: Sheet metal, automotive bodywork, glass handling, commercial kitchen meat/fish prep, recycling sort lines
• A7–A9: Heavy glass handling, blade-edge processing, salvage and demolition with exposed metal, butcher shop primal cuts

The fiber matters as much as the rating

Two gloves can both rate A5 and behave very differently in the field. The reason is the underlying fiber and weave.

Kevlar (DuPont aramid) has been the workhorse cut-resistant fiber for decades. It hits high cut levels at the cost of being somewhat thick and a bit warm. Kevlar is also weak against UV and bleach — wash it in chlorine bleach and you'll lose the rating long before the glove looks worn.

HPPE (High-Performance Polyethylene) is what most modern cut-resistant gloves use, including our CUTShield line. HPPE is lighter and more flexible at equivalent cut levels, doesn't degrade in UV, and feels less like cardboard on the hand. The trade-off: HPPE has lower heat tolerance than Kevlar. If you're working near a hot surface, Kevlar still wins.

Steel-core / engineered yarn blends push into A7–A9. These usually wrap an HPPE or fiberglass core in a stainless steel filament. They're heavy, stiffer, and uncomfortable for fine work, but for sheet-metal fabrication and butcher work they're often the only thing that holds up.

When we spec a glove, we look at the combination — base fiber, gauge (knit density), and any reinforcement layer. A 13-gauge HPPE single-knit at A4 is a different animal than a 10-gauge HPPE-with-fiberglass-core also rated A4.

Why "more cut protection" can be the wrong answer

We've watched customers over-spec gloves and lose more hands than they would have with the right rating. The mechanism is simple: the higher the cut rating, the thicker and stiffer the glove, the worse the dexterity, the more likely a worker takes the glove off "for just this one task." A glove that's not on the hand has zero cut protection.

Our standard advice: pick the lowest ANSI level that covers your worst expected hazard, then optimize for fit and grip from there. An A5 that someone wears for 8 hours beats an A8 that comes off after 30 minutes.

Coatings and grip — separate from cut rating

Most cut-resistant gloves are dipped or coated on the palm. The coating handles grip and abrasion; the underlying knit handles cut. Common coatings:

• Nitrile foam: good dry grip, decent in light oil, breathable. Our most-recommended for general industrial work.
• Polyurethane (PU): thinnest, best for fine work, mediocre in oil. Good for assembly lines.
• Latex: excellent grip in dry conditions, terrible in oil. Allergy concerns in food and medical settings.
• PVC: chemical and abrasion resistance, less dexterous. Heavy-duty industrial.
• Sandy or micro-foam nitrile: our preferred for wet and oily work; the texture maintains grip better than smooth coatings.

If your hazard is cut and grip in oil — which is most automotive and metalworking — the right answer is usually an HPPE A4–A5 base with sandy nitrile palm coating, not the highest possible cut rating.

Reading the cuff stamp

Every compliant glove has a marking, usually on the cuff or palm, showing its rating. In the US that's typically ANSI/ISEA 105-2016 with the cut level printed alongside other ratings (abrasion, puncture). In Europe it's EN 388, which uses a four-to-six-digit code where each digit is a rating (abrasion, cut, tear, puncture, TDM cut, impact).

If you only have an EN 388 glove and you're trying to translate to ANSI: the fifth digit (the letter A through F under the new EN 388:2016 standard) is roughly comparable to ANSI's A1–A6 range. They're not interchangeable, but they're close enough for procurement decisions.

Care and replacement — the part that's often missed

Cut ratings degrade. Every wash, every chemical exposure, every UV-heavy outdoor day takes a percentage off. We tell our buyers to assume:

• HPPE gloves: hand-wash with mild detergent, air dry, no bleach. Bleach destroys the rating in a single wash.
• Kevlar gloves: machine wash cold with mild detergent. UV degrades them — store indoors.
• Replace when: visible wear on palm coating, snags or pulls in the knit, or any cut, scuff, or thinning at a high-wear point. A snagged HPPE glove is no longer A5; it's whatever rating a glove with a hole in it gets.

For commercial kitchens or food processing, we recommend a hard replacement schedule (every 90 days under daily use) regardless of visible wear, since unseen contamination and fiber fatigue accumulate.

Our recommended starting points

If you're new to cut-resistant gloves, here's what we suggest as a first-trial pack:

• Light industrial / automotive: our CUTShield A3 or A4 with nitrile foam coating — flexible enough for most assembly work, enough cut for sharp metal trim.
• Commercial kitchen prep: JH Safety A5 food-grade with the 3-color set for HACCP cross-contamination protocol.
• Sheet metal / glass: A6 HPPE with reinforced palm. Step up to A7+ only if A6 has demonstrably failed in your specific use.
• Demolition / salvage: A5 with sandy nitrile palm and extended cuff or matched cut-resistant sleeves for forearm coverage.

If you're not sure which level fits your work, the safest move is to spec a small trial of two adjacent levels (A4 and A5, say) and let the crew tell you which one they actually keep on for the full shift.

The G & F R&D shorthand

When a customer asks us for "the best cut-resistant glove," we ask back: best for what hazard, what task duration, what hand size range, and what's the budget per pair? The right answer changes wildly across those four. The wrong answer — buying the highest ANSI level out of caution — costs more per pair, fits worse, and leads to gloves coming off the hand. That's the fastest way to a workplace injury.

If you have a specific use case and want guidance, our team takes those questions directly. We've spent four decades making cut-resistant gloves, and we'd rather spec one well than sell ten of the wrong thing.
