• Made with the highest quality metal alloy known in the industry; tungsten steel.
• Sharpened on both sides at the same time so that the blade comes down to an even point.
• The material and sharpening process allow for a longer blade life.

Martelli's  unique sharpening system has created a blade that is in for the long haul. The blades will last approximately 3-5 times longer than ordinary blades. To maximize your blade life and efficiency in cutting, use it with the Martelli ergonomic rotary cutter and one of their commercial-grade mats. When you replace a blade, make sure you discard the old one in a safe manner. Three sizes available (28mm, 45mm, and 60mm).

Please do not merely throw them in the trash!
