OLFA is a leader in tool innovation, and these blades are made in Japan using strictly controlled heat treatment processes. This ensures:

• Exceptional Sharpness: Carefully honed edges allow for cutting without great effort, reducing hand fatigue.
• Break Resistance: Although the blades are very thin, the high-quality steel features flexibility and strength, preventing breakage even when working with harder materials.

Frequently Asked Questions (FAQ)

Do these blades fit other knives?

These blades are designed specifically for the OLFA AK-4 model. While they may fit some other holders, full stability and safety are only guaranteed with the specified tool.

How many cuts does one blade withstand?

This depends on the material being cut (e.g., paper vs. plastic). However, due to special steel hardening, these blades last on average 30-50% longer than standard blades.
