Olfa Art Knife Replacement Blades

This pack contains twenty-five AK-1 and AK-4 blades made from high-quality carbon tool steel. They fit OLFA art knives and handle paper, foam core, vinyl and film. The compact container measures 2x1-1/2x1/2 inch and separates new blades from used ones.

Storage and Handling

The blades arrive new in a dedicated case that keeps sharp edges protected during storage. No power draw, noise or thermal output is generated by this passive accessory. The carbon steel construction resists dulling through repeated cutting tasks.

Upgrade From Dull Blades

Swap out worn edges when cuts start to tear or require excess force. The twenty-five count suits frequent users who need consistent sharpness on hand. Buyers needing specialised blade profiles or bulk quantities beyond this pack should look elsewhere.

Questions about this item

How do I load a fresh AK-1 or AK-4 blade into my OLFA art knife without cutting myself?

Slide the blade into the knife's channel until it clicks, keeping fingers clear of the edge. The container has a dedicated new-blade compartment so you handle only the spine.

When will the carbon tool steel blades need replacing during regular paper and vinyl cutting?

Replace a blade when it stops slicing cleanly or starts tearing foam core and film. The pack supplies 25 AK-1 and AK-4 blades for extended use.

What is the first sign the blade is worn out during a long cutting session?

The edge dulls first, causing drag and ragged cuts on paper, vinyl or foam core before the steel itself deforms.
