OLFA Standard Spare Blades, Dual Edge, Fits Safety Knifes, Alloy Steel - Pack of 5

Dual-edge means both sides of the blade are sharpened. When one edge becomes dull, you can flip the blade to use the other edge, effectively extending the blade life before a replacement is needed.

They’re ideal for precision cuts in paper, cardboard, and lightweight materials. They deliver clean, accurate results with minimal effort.

First, ensure the knife is switched off and the blade guard is engaged. Open the blade holder, remove any old blade, insert a new OLFA spare blade with the sharp edges facing the correct direction, then close the holder and re-engage the guard.

These blades are engineered for longevity and consistent performance. Sharpening and edge life depend on material type and cutting frequency, but these alloy-steel blades are designed to maintain sharpness over many cuts with proper use.

Yes. They are designed specifically for SK-4, SK-5, and SK-9 safety cutters and will fit securely when installed correctly, providing smooth and controlled cuts.

Store blades in a closed, designated blade container away from children and pets. Handle blades with care, avoid touching the sharp edges, and replace the blade guard after use to minimize risk.
