Cut-Resistant Work Gloves: ANSI/ISEA Cut Levels Explained

By Vynado Editors | July 6, 2026 | 9 min read

A glove tag that says "cut resistant" tells you almost nothing on its own. The number next to it does the real work. ANSI/ISEA 105 is the standard most US glove makers test against, and it sorts gloves into nine cut levels, A1 through A9, based on how many grams of cutting force a blade needs to slice through the material in a controlled lab test. Once you know how to read that number, glove shopping stops being guesswork.

How the Test Actually Works

The ANSI/ISEA 105 cut test uses a machine that drags a straight blade across a swatch of the glove material under a fixed weight, then measures how many grams of downward force were needed before the blade broke through. More grams of force required equals a higher cut level. The test is mechanical and repeatable, which is why the rating is more trustworthy than words like "heavy-duty" or "extreme grip" printed on packaging.

A1–A2: Light cut resistance, similar to a sturdy pair of work gloves. Suitable for light material handling with minor sharp edges.
A3–A4: Moderate resistance, a common range for general warehouse, glass handling, and metal fabrication work.
A5–A6: High resistance, typically built with para-aramid or high-performance polyethylene fibers, used around sheet metal, blades, and glazing work.
A7–A9: Very high resistance, reserved for jobs with serious laceration risk such as recycling sorting, meat processing, and glass fabrication.

Cut Level Is Not the Whole Story

A high cut level number does not automatically make a glove safe for every hazard. The ANSI/ISEA 105 standard also rates gloves separately for puncture resistance and abrasion resistance, and a glove can score high on cut and low on puncture. A box cutter blade sliding across a palm is a cut hazard. A screwdriver tip pressed straight into the same spot is a puncture hazard, and it takes a different fiber structure to stop it. Read all three ratings on the tag, not just the cut number, before deciding a glove fits the job.

Material Matters for Comfort, Not Just Rating

Two gloves with the same A4 rating can feel completely different on the hand. Para-aramid fiber (the generic term for materials in the Kevlar family) resists heat and cutting well but can feel stiff. High-performance polyethylene fibers achieve similar cut ratings with more flexibility and a cooler feel, which matters over a full shift. Steel or fiberglass fiber blends push cut resistance higher but add weight and reduce dexterity for fine work. Match the fiber, not just the number, to how much fine motor control the job demands.

Coating Choices Change the Grip, Not the Cut Rating

The cut-resistant liner does the cutting protection. The palm coating on top of it does the gripping. Common coating options:

Nitrile: Good grip in dry and lightly oily conditions, reasonably abrasion resistant, the most common all-purpose coating.
Polyurethane: Thinner and more flexible than nitrile, favored for fine assembly and electronics work where tactile sensitivity matters.
Latex: Excellent wet grip, less common now due to allergy concerns for some workers.
Sandy nitrile or foam nitrile: Textured finish that improves grip on oily or wet metal parts.

None of these coatings meaningfully change the underlying cut rating; they sit on top of the cut-resistant liner and affect only grip and dexterity.

Where Cut Ratings Break Down in Real Use

The lab test drags a blade in one straight, controlled motion. Real job-site cuts are rarely that clean. A glancing slash, a puncture-then-tear, or repeated sawing motion can behave differently than the standard test predicts, and no glove eliminates the need for careful handling of sharp tools. Cut-resistant gloves reduce the severity and likelihood of injury; they do not make contact with a blade safe. Treat the rating as risk reduction, not immunity.

Buying Rule of Thumb

Match the cut level to the sharpest hazard you handle regularly, not the rare worst case, then choose the coating based on whether the job is dry, wet, or oily. Check the puncture and abrasion ratings on the same tag before assuming the cut number tells the whole story.

Fit and Replacement

A cut-resistant glove that is too loose bunches at the fingertips and reduces control, which increases the chance of a slip that puts skin near the blade in the first place. A glove that is too tight strains the fibers and can reduce their effective cut resistance over repeated flexing. Replace gloves when the coating cracks, when fibers show visible wear at stress points like the palm crease, or after any direct blade contact even if the glove was not fully cut through, since impact can weaken the fiber structure invisibly.
