Pros:
- Classic die-cast design that owners report using for decades, with a smooth, secure retractable mechanism.
- Three blade positions let you set a short exposure for scoring and a longer one for through cuts.
- Handle stores up to 10 spare blades, so a fresh edge is always on the knife.
Con: Blade changes need a screwdriver to open the knife, which is slower than a tool-free design, and a few owners report blade wobble.
Owner review themes point to owners who praise the exceptional durability, with many reporting decades of reliable use, the smooth and secure retractable mechanism, and the razor-sharp cutting. The recurring complaints are that blade changes need a screwdriver to open the knife, and that a few knives show blade wobble.

Best for long, clean scores in drywall, where a fresh edge matters more than a thick blade.
Key specs are an 18mm snap-off utility knife with a ratchet-based locking system that gives unlimited secure cutting positions. It comes preloaded with a Tough Silver LB snap-off blade made from Japanese tool steel, and the blade has 8 snap-off segments. The heavy-duty ABS plastic handle withstands drops, and a stainless-steel support channel maintains blade position for heavy-duty cutting. It accepts any 18mm OLFA blades.

Pros:

Con: Snap-off blades are thinner than trapezoid blades and do not suit scraping or prying, and the ratchet wheel is slow to adjust one-handed.
Owner review themes point to buyers who describe the blades as very sharp and able to cut thick cardboard easily, and who value the fresh edge a snap-off blade gives. The most common criticism is the ratchet wheel, which some owners find slow for one-handed adjustment, and blade changes that are not the fastest when done constantly.

Check current price on AmazonQuestions to ask before buying
What blade depth should I use to score drywall?
Set the blade to cut through the paper face and just into the gypsum core, about the thickness of the paper plus a small bite into the core. A short blade exposure gives better control and a cleaner score, because a long blade can wander and cut deeper than planned. For a full sheet, score the face paper with one firm pass along a straightedge, then snap the sheet along the score and cut the paper on the back. For a cutout around an outlet box, use a short exposure and several light passes rather than one deep push, so the blade follows the box edge instead of drifting into the stud.
Should I choose a retractable knife or a snap-off knife for drywall?
A retractable knife with a trapezoid blade suits most drywall work, because the thick blade holds up to scoring, trimming, and cutting around boxes, and the blade retracts fully for safe carry. A snap-off knife suits long, straight scores where a fresh edge matters, because you can snap off a dull tip in seconds and keep cutting. The snap-off blade is thinner, so it is less suited to prying or scraping. If you cut drywall all day, keep a retractable knife as the main tool and a snap-off knife for long finish scores. If you cut drywall only now and then, one retractable knife covers the job.
How do I cut drywall cleanly without tearing the paper?
Use a sharp blade, a straightedge, and one firm pass with steady pressure. A dull blade tears the paper instead of slicing it, so change the blade at the first sign of drag or ragged edges. Hold the straightedge firmly and keep the knife tight against it, with the blade angled slightly into the cut. Score the face paper first, snap the sheet, then cut the back paper from the folded side. For cutouts, drill a starter hole or plunge the tip carefully at a corner, then cut along the marked lines with light passes. Always cut away from your body and keep your free hand behind the blade path.
How do I change a utility knife blade safely?
Retract or fold the blade first, then open the knife or press the blade release exactly as the maker manual describes. Hold the blade by its flat sides, never by the sharp edge, and keep your fingers clear of the edge while sliding the old blade out. Put the used blade straight into a blade disposal container or a sealed tin, never loose in a pocket or a trash bag. Seat the new blade fully on its holder until it clicks or locks, then close the knife and test the retraction before cutting. Wear gloves and eye protection during a blade change, and never force a blade that does not fit, because a wrong blade can slip out during a cut.
How should I store a utility knife so nobody gets cut?
Retract the blade fully or fold the knife closed before putting it down, every time, even for a short pause. Store the knife in a sheath, a tool pouch pocket, or a drawer with the blade retracted, never loose in a pocket with keys or a phone. Keep spare blades in the handle storage or in a closed blade dispenser, and keep used blades in a marked sharps container until disposal. Store knives out of reach of children, and never leave an open knife on a workbench where someone can reach across it. Check the blade is retracted before handing the knife to another person.
Frequently asked questions
Can a utility knife cut through drywall in one pass?
A sharp utility knife can score the face paper and part of the core in one pass, but the usual method is to score the face, snap the sheet, and then cut the back paper. Trying to force a full cut in one pass tears the paper and leaves a ragged edge. Use a short blade exposure and let the snap do the breaking.
How many times can I use one utility blade on drywall?
A standard trapezoid blade stays sharp for several sheets of drywall, but gypsum dulls an edge faster than cardboard. Change the blade when it starts to drag, tear the paper, or need extra pressure. A snap-off blade gives a fresh edge with one snap, so it lasts through more scores before a full blade change is needed.
What is the difference between a snap-off blade and a standard trapezoid blade?
A snap-off blade is a long, thin blade scored into segments, so you snap off a dull tip for a fresh edge. A trapezoid blade is a short, thick blade that you replace whole when it dulls. Snap-off blades cut cleanly and give many fresh edges, while trapezoid blades are stronger and better for trimming, prying, and cutting around boxes.
Do I need a special blade to cut drywall?
No special blade is needed. A standard trapezoid utility blade or an 18mm snap-off blade both cut drywall well. Use a fresh, sharp blade, and keep spares on hand. Hook blades exist for cutting drywall and flooring, but a standard blade covers most household drywall cuts.
How do I dispose of used utility blades safely?
Put used blades in a dedicated blade disposal container, a sealed metal tin, or a puncture-proof box marked for sharps, and tape the lid shut before throwing it away. Never put loose blades in a trash bag, a pocket, or a drawer. Some hardware stores and recycling centers accept sharps containers, so check local rules before disposal.
