The OLFA 9mm AB-5B Snap Blades (5-pack) are widely considered the best choice for precision cutting due to their exceptional sharpness, durability, and reliable snap-off design. Made from high-quality Japanese tool steel, these ultra-sharp blades effortlessly slice through paper, cardboard, film, and vinyl, making them an essential, long-lasting tool for professionals and hobbyists alike.
Finding a utility knife blade that maintains its edge through thick cardstock, vinyl, and precision cardboard trimming is frustrating when you rely on cheap steel that dulls in minutes. If you do detailed craft work, model building, or warehouse shipping prep, your cuts need to be razor-sharp every single time. That level of reliability is exactly why professionals and makers continually search for the best 1105995 olfa 9mm ab-5b snap blades, 5pk to stock their toolboxes and workstations.
Priced at an accessible $6.99 for a 5-pack, this replacement set delivers Japanese tool-grade carbon steel designed to fit standard 9mm utility knives. Instead of throwing away an entire blade when the tip loses its bite, you simply snap off the dull segment to reveal a fresh, factory-honed edge. In this review, we examine how these specific snap-off blades perform under heavy daily use, what materials they handle best, and how to snap and replace them without safety risks.
Whether you are trimming window tint, cutting intricate architectural models, or opening dozens of master cartons daily, having the right cutting edge prevents jagged edges and accidental slips. Let’s dive into the specifics of the 1105995 Olfa AB-5B pack and see why they remain a staple for precision cutters everywhere.

Why Choose Olfa 9mm AB-5B Replacement Blades
Superior Japanese Tool Steel Quality
The manufacturing process behind Olfa blades relies on high-grade Japanese carbon tool steel, specifically formulated to achieve a sharper initial angle than standard utility blades. When you examine the edge under magnification, the grind is uniform from heel to tip. This precise manufacturing standard ensures that the metal does not chip easily when cutting dense materials like rubber, leather, or heavy plastic sheeting. Cheaper alternatives often use softer steel that folds or dulls immediately upon striking a staple or hard surface, but Olfa’s double-honed edge retains its slicing capability significantly longer.
Consistent Snap-Off Segments
One of the primary frustrations with low-cost snap blades is inconsistent scoring along the snap lines. If a blade fails to break cleanly at the designated score mark, it can leave a jagged, dangerous edge or ruin the remaining blade length inside your handle. The 1105995 Olfa AB-5B snap blades feature laser-etched score lines engineered to snap cleanly every single time when used with a proper tool or pliers. This consistency means you waste zero blade length and always get a squared, sharp tip ready for immediate cutting.
Key Features and Specifications of the AB-5B Pack
Exact Dimensions and Compatibility
The AB-5B designation indicates a 9mm width profile, making these blades universally compatible with almost any standard 9mm utility knife handle on the market, though they fit Olfa’s own S, L-A, and standard 9mm stainless steel slide knives with absolute precision. Each blade features multiple snap-off segments, allowing you to refresh the tip up to 12 or 13 times per single blade depending on the specific model layout. At $6.99 for a five-pack, your total cost-per-cutting-edge is remarkably low, which matters heavily if you go through multiple segments a day.
Protective Plastic Dispenser Case
Loose blades rolling around in a toolbox or drawer are a major safety hazard and quickly dull themselves through friction against other metal tools. The 1105995 Olfa AB-5B 5-pack comes housed in a rigid, slide-dispensing plastic case that keeps the sharp edges isolated and secure. The case design allows you to dispense a single blade safely without touching the cutting edge, and it also serves as a safe temporary storage location for used blades if your handle does not feature a built-in snap-off tool.
Best Applications for 9mm Utility Knife Blades
Graphic Design, Crafting, and Model Making
Precision is non-negotiable when working with mounting board, foam core, stencil film, and heavy watercolor paper. The thin 9mm profile of the AB-5B blade allows you to maintain high visibility right at the point of contact, unlike bulky trapezoid drywall blades that block your line of sight. Model makers rely on these blades to cut balsa wood, styrene sheets, and delicate masking tape without fraying the edges. Because you can snap off the tip the moment it catches or drags, your delicate curve cuts and straight edges remain crisp throughout multi-hour crafting sessions.
Window Tinting, Vinyl Wraps, and Sign Making
Vehicle wraps, window tint films, and adhesive vinyl require an ultra-sharp point to trim excess material cleanly against glass, rubber gaskets, and vehicle body panels. A dull blade will tear vinyl rather than slice it, leaving ragged edges that peel up over time. Installers specifically look for the best 1105995 olfa 9mm ab-5b snap blades, 5pk because the carbon steel edge slices cleanly through cast and calendered vinyl without requiring excessive downward pressure that could scratch the underlying paint or glass surface.
How to Safely Safely Snap and Replace Dull Blade Segments
Using a Pocket Tool or Pliers
Never attempt to snap a blade segment with your bare fingers, even if you are experienced. To snap a dull segment safely, extend the blade out of your handle by exactly one segment length so the score line rests just outside the metal nose of the knife. Grip the exposed tip firmly using a dedicated snap-off tool, multi-tool pliers, or the built-in snapper slot located on the end cap of most Olfa knife handles. Apply a steady, downward bending pressure away from your body and face. The segment will snap cleanly along the score line.
Disposing of Used Segments Safely
Because discarded blade tips remain dangerously sharp, tossing them loosely into a standard household trash can risks puncturing the plastic bag and injuring waste handlers. Always collect your used segments in a dedicated blade disposal container, an empty metal tin, or slide them back into the designated used-blade slot of your Olfa storage case if available. Taking two seconds to properly contain your used segments prevents accidental cuts in your workspace.

Frequently Asked Questions
Will the 1105995 Olfa AB-5B blades fit non-Olfa knife handles?
Yes. These are standard 9mm blades engineered to fit the universal track and locking mechanisms of almost any brand of 9mm utility knife, pocket slide knife, or graphic arts cutter.
How many snap segments are on each blade?
Each blade in the 5-pack features multiple pre-scored segments, typically providing 13 fresh cutting tips per individual blade before the entire strip needs replacement.
Are these blades stainless steel or carbon steel?
They are made from premium Japanese carbon tool steel. Carbon steel holds a significantly sharper edge and lasts longer than stainless steel, though it requires basic care to prevent surface oxidation in humid conditions.
Can I use these blades for cutting drywall?
While they can score the paper layer of drywall in a pinch, 9mm snap blades are far too thin and flexible for heavy drywall cutting. You should use a heavier 18mm or 25mm utility blade for construction and drywall applications.
How do I know when it is time to snap off a segment?
If you notice you have to press harder to get a clean cut, or if the cut material begins to tear, fray, or bunch up instead of slicing smoothly, the tip is dull. Snapping off a single segment immediately restores factory-level sharpness.
If your current cutting tools leave ragged edges, slow down your workflow, or require constant blade changes, upgrading to the 1105995 Olfa AB-5B snap blades transforms how you tackle precision tasks. At under seven dollars for a five-pack, keeping your cuts clean, straight, and effortless has never been more cost-effective.
