The Ultimate Guide to Cut-Resistant Gloves: ANSI Ratings Explained

Cut-resistant gloves can look surprisingly similar. Two pairs may use lightweight knit shells, nitrile-coated palms, and nearly identical designs, yet provide very different levels of protection against sharp edges.

That is why simply buying a glove labeled "cut resistant" is not enough.

For safety managers, procurement professionals, maintenance supervisors, construction teams, and nuclear facilities, understanding cut ratings provides a more useful way to compare gloves and select hand protection for the hazards workers actually face.

In the United States, one of the primary references for evaluating cut-resistant hand protection is ANSI/ISEA 105. The current ANSI/ISEA 105-2024 standard provides a classification system for hand and arm protection, including a cut-resistance scale from A1 through A9.

This guide explains what those ratings mean, why a higher number is not automatically the right choice, and which other glove characteristics should be considered before selecting hand protection.

Why Cut-Resistant Gloves Matter

Workers throughout industrial, manufacturing, construction, maintenance, power generation, and nuclear environments regularly handle materials capable of causing cuts and lacerations.

Potential hazards can include:

• Sheet metal
• Sharp equipment components
• Machined parts
• Glass
• Metal edges and burrs
• Construction materials
• Maintenance tools and components
• Scrap materials

OSHA's 29 CFR 1910.138 Hand Protection standard requires employers to select and require appropriate hand protection when workers' hands are exposed to hazards including severe cuts, lacerations, abrasions, punctures, chemical burns, thermal burns, and harmful temperature extremes.

OSHA also states that appropriate hand protection should be selected based on its performance characteristics relative to the task being performed, conditions present, duration of use, and identified hazards.

What Is ANSI/ISEA 105?

ANSI/ISEA 105 is the American National Standard for Hand Protection Classification. The standard establishes a classification system for performance characteristics of hand and arm protection.

The current ANSI/ISEA 105-2024 standard addresses several performance properties and uses a nine-level scale, A1 through A9, for cut resistance.

Information about the current standard is available from the International Safety Equipment Association's hand protection resource.

The key concept is straightforward:

As the ANSI cut rating increases from A1 toward A9, the tested material provides greater resistance to the standardized cutting test.

That does not mean every workplace should automatically purchase A9 gloves.

Glove selection should begin with the hazard.

ANSI Cut Levels A1 Through A9 Explained

ANSI/ISEA 105-2024 maintains the A1 through A9 cut-resistance classification system. Each level represents a defined range of performance during standardized testing.

At a high level, the scale progresses as follows:

• A1 represents the lower end of the cut-resistance scale.
• A2 and A3 provide progressively greater tested cut resistance.
• A4 through A6 occupy the middle and higher portions of the scale.
• A7 through A9 represent the highest cut-resistance classifications.

ANSI explains that the A1 through A9 scale is based on how well glove material withstands a blade-cut test. The current standard also covers additional hand-protection performance properties beyond cut resistance.

For a detailed explanation of the standard and current classification system, review the ANSI overview of ANSI/ISEA 105-2024 and its hand-protection classifications.

A Higher Cut Rating Does Not Automatically Mean a Better Glove

This is one of the most important concepts for PPE buyers.

An A9 glove is not automatically "better" than an A4 glove for every application.

The real question is whether the glove's performance characteristics match the hazards and work being performed.

For example, a worker performing a task that requires substantial finger dexterity may have very different glove requirements from a worker handling extremely sharp or abrasive material.

Glove selection can involve balancing several factors:

• Cut resistance
• Dexterity
• Grip
• Abrasion resistance
• Puncture resistance
• Impact protection
• Chemical resistance
• Fit
• Comfort
• Duration of use

This is consistent with OSHA's requirement that employers evaluate hand protection relative to the tasks being performed, workplace conditions, duration of use, and identified hazards.

Start With the Hazard Assessment

The glove-selection process should begin before anyone starts comparing products.

OSHA's 29 CFR 1910.132 general PPE requirements require employers to assess the workplace to determine whether hazards are present or likely to be present that necessitate PPE. When hazards are identified, appropriate PPE must be selected for those hazards.

For hand protection, questions may include:

• What sharp objects or edges will the worker handle?
• How frequently will the worker encounter the hazard?
• What type of grip does the task require?
• Is puncture resistance also important?
• Are abrasion hazards present?
• Are chemicals, heat, or other hazards also present?
• How much dexterity does the worker need?
• Will the gloves be worn for extended periods?
• Does the task involve machinery that introduces additional hazards?

Once those questions are answered, the ANSI rating becomes much more useful because the safety team is matching glove performance to an identified hazard instead of selecting PPE based solely on a number.

What Does an ANSI A4 Cut Rating Mean?

A4-rated gloves occupy the middle portion of the A1 through A9 cut-resistance scale and can be useful for applications where the hazard assessment indicates that level of tested cut resistance is appropriate.

For example, ShopUniTech's UniFlex Nitrile Dipped HPPE A4 Cut-Resistant Gloves use a 13-gauge HPPE knit shell with a micro-nitrile coating on the palm and fingers.

The glove's A4 cut rating is only part of the selection picture. Grip, dexterity, fit, abrasion resistance, puncture resistance, coating, and the actual workplace hazard should also be evaluated.

When Might an A6 Glove Be Appropriate?

For work requiring a higher level of tested cut resistance, an A6-rated glove may be considered when supported by the hazard assessment.

The UniFlex Pro A6 Cut-Resistant Gloves, for example, use an 18-gauge HPPE knit incorporating steel/glass fiber with a micro-nitrile palm and finger coating.

Moving from A4 to A6 should not simply be treated as an automatic upgrade. The correct selection depends on the task and the full range of hazards involved.

Safety teams should evaluate whether the additional cut-resistance performance is appropriate while also considering grip, dexterity, fit, wear time, and other required protective characteristics.

Cut Resistance Is Not the Same as Puncture Resistance

One of the most common mistakes when evaluating gloves is assuming that a high cut rating describes every type of mechanical protection.

Cut and puncture hazards are different.

A sharp edge moving across a glove creates a different challenge than a pointed object applying force to a concentrated location.

ANSI/ISEA 105 therefore addresses multiple hand-protection performance characteristics rather than treating all mechanical hazards as one category.

If workers encounter nails, wires, sharp projections, or other puncture hazards, the hazard assessment should consider those hazards specifically rather than relying on the cut rating alone.

Cut Resistance Is Not Impact Protection

Impact hazards also need to be considered separately.

Workers performing industrial maintenance, material handling, construction, or heavy equipment work may require protection from impacts to the back of the hand in addition to cut protection.

A glove may offer strong cut resistance without providing the impact protection required for a particular job.

For tasks where both hazards are present, products designed and rated for multiple performance characteristics may be appropriate. For example, the Ironclad Command Impact Glove sold by ShopUniTech is listed with ANSI A6 cut, A4 abrasion, A3 puncture, and ANSI Impact Level 2 ratings.

The important lesson is not that every high-risk task requires this particular combination. It is that safety managers should evaluate each hazard independently rather than assuming one rating describes the glove's total protective performance.

Why Grip Matters

Cut resistance receives much of the attention, but grip can be equally important to the usability of a work glove.

A glove that makes tools, parts, or materials difficult to control may not be appropriate for the task even if its cut rating looks impressive.

Coated work gloves frequently use materials such as nitrile on the palm and fingers to provide grip while allowing the back of the glove to remain more flexible.

Grip requirements may vary depending on whether workers handle:

• Dry components
• Lightly oily components
• Tools
• Metal parts
• Construction materials
• Maintenance equipment

Again, the best glove is the one whose complete performance characteristics match the actual work.

Dexterity Should Not Be Ignored

Many industrial tasks require workers to manipulate fasteners, operate controls, use hand tools, or perform other precise movements.

That makes dexterity an important part of glove selection.

Safety teams should avoid treating the highest achievable protection level as the default specification without considering how the glove affects the work itself.

Workers are more likely to use PPE correctly when it fits properly and allows them to perform their assigned task effectively.

Fit Is Part of Hand Protection

A properly selected glove must also fit the worker.

Gloves that are too large can interfere with dexterity and grip. Gloves that are too small can restrict movement and may be uncomfortable during extended wear.

OSHA's general PPE requirements specifically require employers to select PPE that properly fits affected employees.

When standardizing gloves across an organization, procurement teams should consider the required size range as well as the cut rating.

Cut-Resistant Gloves in Manufacturing

Manufacturing operations can expose workers to sharp components, metal edges, tools, materials, and equipment during production and maintenance activities.

Potential applications for cut-resistant gloves may include:

• Material handling
• Fabrication
• Mechanical maintenance
• Handling metal components
• Assembly work
• Equipment repair

The required protection level should be determined from the specific hazards associated with each task rather than establishing one cut rating for an entire facility without further evaluation.

Cut-Resistant Gloves in Construction

Construction personnel regularly work with materials and equipment capable of producing cuts, abrasions, and punctures.

Depending on the trade and activity, workers may encounter metal edges, wire, tools, fasteners, sheet material, and other sharp objects.

Glove selection should account for the specific work, the required level of dexterity, environmental conditions, and any secondary hazards.

A glove appropriate for material handling may differ from the protection needed for metal fabrication, demolition, electrical work, or another specialized construction task.

Cut-Resistant Gloves in Nuclear Outage and Maintenance Work

Nuclear facilities present an additional consideration because a worker may face both industrial and radiological hazards during the same task.

Refueling outages, maintenance activities, equipment disassembly, material handling, and modification work can involve sharp or abrasive components while simultaneously requiring contamination-control practices.

This may require a hand-protection system rather than relying on a single glove to address every hazard.

Cut Resistant Does Not Mean Cut Proof

This point deserves particular emphasis.

Gloves should not be treated as making a worker's hands invulnerable to sharp objects.

OSHA's guidance concerning cut and laceration hazards specifically notes that cut-resistant gloves are not cut-proof. They can provide protection from cuts but do not completely eliminate the potential for injury.

The same OSHA guidance also emphasizes that the characteristics of the gloves need to be appropriate for the job.

Engineering controls, machine guarding, safe work practices, proper tools, employee training, and PPE can all have roles in controlling cut hazards.

When Should Cut-Resistant Gloves Be Replaced?

Cut-resistant gloves should be inspected as required by the employer's PPE program and according to applicable manufacturer instructions.

Visible damage, deterioration, compromised coatings, or other changes in condition can affect whether PPE remains suitable for use.

OSHA's general PPE rule states that defective or damaged PPE shall not be used.

Organizations should establish a process for removing unacceptable gloves from service and replacing them before workers continue performing tasks requiring hand protection.

Common Mistakes When Selecting Cut-Resistant Gloves

Choosing the Highest Rating Without Assessing the Task

A higher ANSI rating represents greater tested cut resistance. It does not automatically mean the glove is the best choice for every worker or application.

Looking Only at Cut Resistance

A task may also involve abrasion, puncture, impact, chemical, heat, grip, or other requirements.

Ignoring Dexterity

Workers need to be able to perform the assigned job safely while wearing the selected glove.

Ignoring Fit

PPE must fit the employee properly. Glove sizing should therefore be part of the purchasing decision rather than an afterthought.

Assuming Similar-Looking Gloves Provide Similar Protection

Appearance is not a performance rating. Two gloves with similar knit shells and coatings may have different tested protective characteristics.

Treating Cut Resistance as Cut Proof

No cut-resistant glove should create a false sense of security around sharp objects, machinery, or blades.

A Practical Cut-Resistant Glove Selection Checklist

Before selecting or standardizing a cut-resistant glove, consider the following questions:

• Has the task been evaluated for hand hazards?
• What causes the potential cut?
• What level of cut resistance is appropriate for the identified hazard?
• Are puncture hazards also present?
• Is impact protection required?
• Are chemical or thermal hazards present?
• What type of grip is needed?
• How much dexterity does the work require?
• Will the glove be worn for extended periods?
• Does the glove fit the worker properly?
• Is the glove compatible with other required PPE?
• Has the manufacturer provided the necessary performance information?
• Is there a process for inspecting and replacing damaged gloves?

Choosing Between A4 and A6 Cut-Resistant Gloves

For organizations comparing multiple levels of cut protection, the decision should return to the hazard assessment.

An A4 and an A6 glove do not represent "good" and "better" in isolation. They represent different tested levels of cut resistance.

ShopUniTech offers both UniFlex A4 Cut-Resistant Gloves and UniFlex Pro A6 Cut-Resistant Gloves for industrial applications where those respective performance characteristics are appropriate.

The right choice depends on the task, cut hazard, other hazards present, fit, required grip, dexterity, and the employer's PPE assessment.

Conclusion: Match the Glove to the Hazard

ANSI cut ratings provide safety managers and PPE buyers with a valuable tool for comparing cut-resistant hand protection, but the rating should never replace a proper hazard assessment.

The most important question is not, "What is the highest ANSI cut level available?"

It is, "What protection does this worker need for this task?"

ANSI/ISEA 105-2024 provides a common classification system for evaluating glove performance, while OSHA requires employers to select hand protection based on the task, workplace conditions, duration of use, and identified hazards.

When employers combine those principles with proper fit, grip, dexterity, worker training, inspection, and safe work practices, cut-resistant gloves become one component of a much stronger hand-safety program.
