STANLEY

Stanley products on this page cover several cutting mechanisms. The InterLock Snap-Off Knife uses a segmented blade and a locking body. FatMax appears as a conventional retractable utility knife and a folding retractable model. The Original Retractable Knife is listed at 155mm, while QuickSlide is a pocket format with belt clip. Replacement choices include ten 1991B carbide utility blades, a yellow dispenser containing ten blades and ten heavy-duty 1992B blades. The pack title or blade number is essential because blade shape, thickness and mounting can differ.

Choose the knife from the material, cut direction, access and workplace risk, then confirm its supported Stanley blade and change method. The current AutoMotoPart selection contains 8 Stanley items, led by 7 tools entries, 1 interlock snap off knife entry. These Stanley figures describe the range on this page rather than every product the brand may make elsewhere.

Inspect the body, slider, lock, hinge, nose, blade carrier and fasteners before every use. Fit only an intact compatible blade with power and nearby machinery isolated. Work on a stable sacrificial surface, secure the material and keep the free hand out of the cut line. Extend only enough blade for the job and cut away from the body with controlled pressure. A retractable blade is not automatically self-retracting; return it manually unless the exact knife states otherwise.

Snap-off segments need a designed snapping tool or the knife's supported method, with eye protection and control of the sharp fragment. Never bend a segment towards another person or snap it by hand. Folding knives must be fully locked in their working position and closed before pocket or belt storage. Replace a dull, chipped, bent or contaminated blade rather than forcing it, and store used blades in a rigid sharps container. Gloves should improve grip and cut resistance without reducing control, but they never make the exposed edge harmless. The products below are a selection guide; current Stanley instructions and workplace risk assessment govern use.

Stanley: understand the range before choosing

Stanley is a hand-tool brand with a long-established utility-knife range. The current collection contains five knife bodies and three ten-blade packs: an InterLock snap-off knife, FatMax retractable and retractable-folding designs, the 155mm original retractable knife, a QuickSlide pocket knife, carbide 1991B blades, a yellow blade dispenser and heavy-duty 1992B blades. A knife body and blade must be matched by exact type, not just brand.

AutoMotoPart currently lists 8 Stanley items. The largest Stanley groups are 7 tools entries, 1 interlock snap off knife entry. Stanley totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Stanley listing, its current technical information and the item in front of you must agree.

What the Stanley page actually covers

Product group in this rangeCurrent entriesSelection focus
Tools7Confirm exact knife or blade reference, blade geometry, carrier, locking mechanism, material, cut, PPE, change method and disposal route.
INTERLOCK SNAP OFF KNIFE1Confirm exact knife or blade reference, blade geometry, carrier, locking mechanism, material, cut, PPE, change method and disposal route.

Seven items are grouped as hand tools and one uses a product-specific snap-off description. Five are complete knives and three are blade packs. The 1991B and 1992B codes identify different blade families, while the yellow dispenser title needs its blade reference confirmed on the pack. The InterLock segmented blade is not a substitute for a standard utility blade used by the retractable bodies.

Build a reliable shortlist

Plan the cut before selecting the tool. Sheet, carpet, packaging, cord, trim and thick building material differ in required blade depth and support. A folding body helps compact storage; a retractable body provides adjustable exposure; a snap-off blade offers fresh segments. None is suitable where hidden live services or an uncontrolled backing surface may be struck.

CheckWhy it mattersUseful evidence

BladeGeometry, thickness, hole pattern and edge determine compatibility1991B, 1992B or supplied blade reference

EnvironmentOil, poor light, height and clutter increase loss of controlClean bench, lighting and stable stance
DisposalLoose used blades can injure handlersRigid marked sharps container and local route

Do not select a longer blade exposure to avoid multiple passes. Use a supported technique and the minimum depth that clears the material. If a cut requires excessive force, stop and check blade sharpness, tool type, backing and hidden fasteners rather than twisting the knife.

Retractable and folding utility knives

The FatMax Retractable Utility Knife and Original 155mm Retractable Knife use a sliding blade mechanism, while the FatMax Retractable Folding Knife adds a hinged body. Stanley's official folding model has an InterLock nose, tool-free blade change and onboard blade storage. Confirm those features on the exact model supplied rather than assuming every FatMax knife is identical.

Before cutting, ensure the blade is seated and the nose closed, then test the lock away from the material. On a folding model, open it fully until its mechanism is engaged. Retract and fold only after the blade stops moving and the work is laid down. Never carry a knife with blade exposed or rely on a pocket to hold a partly closed body.

InterLock snap-off knife

The InterLock Snap-Off Knife uses an 18mm segmented blade in a die-cast metal body with a locking nose. The current collection title is abbreviated, so confirm model and segment width on the item. Set the lock before each cut and leave only the required segment length beyond the nose to reduce leverage and breakage.

When an edge is worn, retract to the supported snapping position and use a designed snapper or Stanley method. Point the segment into a controlled enclosure and wear eye protection. Account for the broken piece immediately and place it in the sharps container. Do not snap a segment over open waste, a vehicle interior or a workbench where it can disappear.

QuickSlide and pocket carry

The QuickSlide listing includes a belt clip and compact sliding format. Verify its exact reference, blade and locking arrangement before use. A belt clip is a carrying feature, not proof that the tool can be worn with an exposed blade or in a position where the slider can be operated accidentally.

Close and check the knife before attaching it to clothing. Keep it out of vehicle seats, airbag areas and reach of children. At height, follow site rules for tethering or tool storage; do not improvise a lanyard through a part not designed for load. Clean debris from the mechanism without fingers crossing the blade path.

1991B, 1992B and dispenser blades

The ten-pack 1991B carbide blades and heavy-duty 1992B blades are separate references. Compare length, thickness, notches and carrier compatibility with the knife manual. Carbide edge wording does not make a blade unbreakable, suitable for prying or compatible with a snap-off body. Use it only for supported cutting applications.

A yellow ten-blade dispenser keeps fresh blades organised, but confirm the blade code inside. Remove one blade at a time through the intended opening and keep the remaining pack closed. Do not use a dispenser as a used-blade container unless it explicitly provides a segregated disposal slot and the workplace method accepts it.

Blade changing, cleaning and disposal

Change blades on a clear bench with the knife fully retracted or folded as its instructions require. Open the body or release the tool-free mechanism without forcing it, note the blade orientation and seat the replacement flat. Close every fastener and lock before testing. Never leave a loose blade under packaging or cloth.

Resin, adhesive and paint can make a slider stick. Use only cleaning methods compatible with the body and handle, dry fully and avoid lubricants that migrate onto the grip or material. A cracked body, loose hinge, failed lock or damaged carrier takes the knife out of service. Dispose of blades through a rigid marked container, not mixed rubbish.

From identification to a checked result

StageGood practice for this rangeMistake to avoid
PlanIdentify material, hidden hazards, backing and cut directionStarting a blind cut towards the body
InspectCheck body, lock, carrier, blade and handle conditionUsing a bent blade or loose nose
SetSecure work and expose only enough compatible bladeExtending extra blade to increase reach
CutUse stable stance, controlled pressure and hands outside the pathTwisting, prying or forcing a dull edge
CloseRetract, fold, clean and put used blades into sharps storageLeaving an exposed knife or loose blade

Record the Stanley knife model and approved blade code in shared workshop storage. Keep fresh blades dry and separated from spent ones. If a knife is issued to multiple users, inspect it at return and remove it from service when any lock, hinge or carrier fault is reported.

Reading real Stanley references

The Stanley names below are examples from the current range and show why the complete description matters. They are not universal Stanley recommendations and should not be treated as a fitment list. Within Stanley, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.

A Stanley logo does not establish blade compatibility. Keep the 1991B, 1992B, segmented or supplied blade reference attached to the exact knife. The FatMax name spans more than one mechanism, so retain the complete model and not just the family word.

Common errors around Stanley products

  • Fitting a 1991B, 1992B or segmented blade into an unsupported Stanley knife.
  • Extending more blade than needed or cutting without a safe backing surface.
  • Holding material in the free hand directly behind the cut.
  • Assuming retractable means the blade retracts automatically when released.
  • Snapping a segment by hand or towards another person.
  • Using a knife tip to pry, scrape sideways or turn a fastener.
  • Carrying a folding or pocket knife before the blade is fully closed and locked.
  • Putting loose used blades into ordinary waste or back with fresh blades.

Stanley questions and answers

Q: What Stanley products are on this page?

A: The range includes five snap-off, retractable, folding or pocket knives and three ten-blade packs.

Q: Are 1991B and 1992B blades interchangeable?

A: Not automatically; compare geometry, thickness and the exact knife's supported blade references.

Q: Can utility blades fit the snap-off knife?

A: No. The InterLock snap-off body uses the specified segmented blade format.

Q: Does retractable mean self-retracting?

A: No. Most listed mechanisms require the user to return the slider; verify the exact model.

Q: How much blade should be exposed?

A: Only the minimum depth needed to pass through the material into a safe backing surface.

Q: How should a segment be snapped?

A: Use the Stanley-supported snapper or method with eye protection and control of the fragment.

Q: Can a dull blade be forced through?

A: No. Stop, secure the work and replace it with the correct sharp blade.

Q: Can a utility knife be used as a pry bar?

A: No. Side loading can break the blade or damage the carrier and cause injury.

Q: How should a folding knife be carried?

A: Fully retract and close it, verify the lock and use only its intended clip or storage.

Q: Can the yellow dispenser hold used blades?

A: Only if its exact design provides a designated used-blade feature; otherwise use a separate sharps container.

Q: What if the slider or lock sticks?

A: Remove the knife from use, clean by its instructions and replace it if the mechanism remains faulty.

Q: How should blades be discarded?

A: Place them immediately in a rigid marked sharps container and use the workplace or local disposal route.
