سكين بلاستيكية قابلة للفك بقبضة مطاطية من ساتا قياس (18x100mm) مكونة من (8) قطع موديل (ST93428SC)

The SATA ST93428SC is a compact snap-off utility knife featuring an 8-point blade with an 18 mm cutting width and a 100 mm blade length. It has a rubber grip for a secure, comfortable hold, a safety lock to prevent accidental exposure of the blade, and a cartridge that can hold three blades. It ships with two SK2 blades for immediate use and is ideal for precise cuts in paper, cardboard, and plastics.

An 8-point blade provides multiple cutting edges in a single blade, allowing you to rotate to a fresh edge as one part dulls. This design extends blade life between replacements and helps maintain clean, precise cuts during prolonged use.

SK2 is a high-carbon steel commonly used for utility knife blades due to its hardness and edge retention. Blades made from SK2 stay sharp longer and resist wear, which is beneficial for frequent scoring and cutting tasks.

The knife features a self-loading mechanism and a cartridge that can store up to three blades. To load, open the blade chamber, insert a fresh blade from the cartridge, and close the chamber. The cartridge keeps extra blades readily accessible so you can rotate to a new edge without stopping your work.

To extend the blade, depress the snap-off mechanism to expose a fresh edge. Use the safety lock to prevent accidental blade exposure when the knife is not in use. Always keep fingers away from the blade path and retract the blade when not cutting to minimize the risk of injury.

This knife is ideal for cutting paper, cardboard, and lightweight plastics. For thicker, harder, or metal-containing materials, use a tool designed for those materials and follow safety guidelines. Avoid forcing the blade through materials that are beyond its intended rating, which can dull or damage the edge.

The knife uses a rubber (TPR) over-molded grip combined with an ABS body. This combination provides a secure, non-slip hold and reduces hand fatigue during longer sessions.

Keep the blade clean and dry after use to prevent corrosion. Store the knife in a dry place, rotate to a fresh edge as needed, and replace blades from the built-in cartridge before the edge becomes too dull. Periodically check the safety lock for smooth operation.

It’s well-suited for hobbyist and professional tasks such as opening boxes, trimming packaging, scoring cardboard for easy folds, making precise cuts in light plastics, and other general cabinetry or craft work that requires a sharp, controllable edge.

If you’re comparing, you can look at similar 18 mm snap-off knives with rubber grips on Fepy. For example, you could explore two close alternatives: https://fepy.com/products/snap-off-knife-18mm-rubber-grip and https://fepy.com/products/18mm-utility-knife-rubber-grip. These options share the same core features (snap-off blades, rubber grip, 18 mm blade width) and allow you to compare blade life, balance, and carrying capacity side by side.

Tips include using a steady, controlled cutting motion rather than forcing the blade through material, rotating to a fresh edge when you notice any dullness, keeping the blade perpendicular to the cutting surface for accuracy, and engaging the safety lock when not actively cutting. Store the knife in a dry place and check the cartridge regularly for spare blades.
