Cutting Performance

We tested the Olfa 45mm on six different fabric types. Here's how it performed:

| Fabric | Layers Cut | Result |

|---|---|---|

| Cotton quilting fabric | 6 layers | Clean, precise cuts |

| Chiffon Fabric ($8–$20, rated 4.2/5) | 2 layers | Excellent—no snagging |

| Jersey Knit ($8–$18, rated 4.4/5) | 4 layers | Smooth with minimal stretch |

| Denim | 2 layers | Handled well, slight resistance |

| Fleece | 4 layers | Clean cuts throughout |

| Silk charmeuse | 1 layer | Flawless |

The blade stayed sharp through all tests. For reference, we also used Dritz Dressmaker Pins ($4–$10, rated 4.4/5) to hold fabric in place before cutting—the combination of sharp pins and a sharp rotary cutter makes a noticeable difference in accuracy.

Value for Money

At $12–$25, the Olfa 45mm sits in the sweet spot between budget cutters and premium options. Replacement blades cost around $8–$15 for a pack of five, which is reasonable given how long each blade lasts with proper care.

Compare this to:

For most home sewists—whether you're running a Singer Heavy Duty 4423 ($180–$250) or a Brother SE600 Embroidery machine ($500–$650)—the Olfa 45mm is the rotary cutter that belongs on your cutting table.

Tips for Getting the Most Out of Your Olfa Cutter

1. Always cut on a self-healing mat — this protects both the blade and your table surface.

2. Replace the blade before it feels dull — a slightly dull blade requires more pressure, which reduces accuracy.

3. Keep the blade clean — wipe it with a lint-free cloth after each session.

4. Use a quilting ruler — pair the cutter with a thick acrylic ruler for perfectly straight lines.

5. Store with the safety lock engaged — always.

Final Verdict

The Olfa Rotary Cutter 45mm earns its 4.7/5 rating. It's precise, durable, comfortable to use, and priced fairly. Whether you're cutting delicate Chiffon Fabric for a blouse or slicing through multiple layers of Jersey Knit for a T-shirt project, this cutter handles it all without complaint.

Buy it if: You want a reliable, long-lasting rotary cutter that won't let you down.

Skip it if: You only cut fabric occasionally and don't mind a budget option.
