Olfa 28mm Rotary Cutter (RTY-1/G) – The Professional’s Choice for Curves
The versatile “medium” cutter designed for precision, tight curves, and intricate fabric work.
If you find a 45mm cutter too bulky for small pieces but want more speed than an 18mm blade, the Olfa 28mm Rotary Cutter is your perfect match. Known as the “workhorse for curves,” this tool strikes the ideal balance between power and agility. It is specifically engineered for projects that require navigating complex shapes, cutting small templates, and managing delicate appliqué.
Why the Olfa 28mm is a Studio Essential:
- Master of Maneuverability: The 28mm blade diameter is the industry standard for cutting tight circles, curved seams, and intricate patterns that require a steady, controlled hand.
- Premium Edge Retention: Pre-loaded with a razor-sharp Olfa blade, forged from high-quality tungsten steel for a “sword-like” edge that stays sharper for significantly longer than standard carbon blades.

- Ambidextrous Performance: Thoughtfully designed for both right and left-handed users. Simply switch the blade to the opposite side of the handle for a customized experience.

Alison –
I use the small ones for the majority of my cutting and the cutter is easy to use. It has a cover for the blade built-in. Also easy to replace the blades when needed.
