How Long Do Rotary Cutter Blades Last?

Rotary cutters are a popular choice when it comes to cutting fabric. They’re fast and easy to use, but they do have their drawbacks. One of the biggest issues people have with rotary cutters is that they can dull really quickly.

The good news is that there are ways you can prevent this from happening. We’ll start by looking at how long blades for rotary cutters last and what factors contribute to them dulling faster than scissors or other types of blades.

Rotary cutter blades are made to last a long time. How long they will last depends on how much you use them, but if you take care of them and sharpen them occasionally, the blade will stay sharp for years.

If your rotary cutter blade becomes dull, don’t try to sharpen it yourself by rubbing it against a sharpening stone or another abrasive surface; this is not recommended and could damage the blade beyond repair.

When you notice that your rotary cutter is no longer cutting as smoothly as it did when new, get replacement blades before continuing with any projects involving fabric sewing or any other project that requires sharp cutting tools.

Do Rotary Cutters Dull Faster than Scissors?

Rotary cutters are designed to handle a variety of materials, from fabric to paper. Scissors, on the other hand, are designed specifically for cutting paper. If you’re using a rotary cutter to cut through thicker materials like cotton or leather, it will dull faster than a pair of scissors would if used on paper alone. This is because when you use your rotary cutter to cut through multiple types of material (e.g., leather), you’re pulling harder and exerting more pressure than if you were just using it for one type of material (e.g., paper).

When comparing how long rotary blade lasts compared with scissors:

  • Rotary blades last longer because they’re harder and stronger than scissors; therefore they don’t dull as quickly when stressed by heavy-duty use in comparison with regular-sized scissors which tend toward being delicate due mainly to their small size

What Factors Dull Rotary Cutters the Most?

There are several factors that can cause your rotary cutter to dull. One of the most common is cutting on a surface that’s too hard for the blade.

If you’re using a mat, cutting paper or fabric, it’s likely that your cutter will dull more quickly than if you were working with soft materials like felt and fleece. If you’re cutting through thick materials like denim or leather, this will also cause your blades to become dull much faster than normal.

Do Cutting Mats Dull Rotary Cutters?

One of the biggest misconceptions about rotary cutters is that they dull quickly, but this isn’t always the case. In fact, if you’re using your cutting mat properly, it can actually protect your rotary cutter from wear and tear.

A good cutting mat provides a surface for you to place your fabric and helps keep everything steady while you’re cutting around the edges. If possible, try to avoid placing fabric directly on surfaces like tables or floors because these will both cause excessive wear on your blade as well as on any other tools that come in contact with it (like scissors).

Can You Buy Replacement Blades for your Rotary Cutters?

If you’ve ever wondered, “How long do rotary cutter blades last?” then the answer is: it depends. There are many factors that can affect how long your blade will last, including:

  • How often and how hard do you use it
  • The size of the blade surface area (the more surface area, the longer it will last)
  • The type of cutting material being cut (i.e., fabric versus paper)

However, even with all of these variables in mind, there are still some general guidelines for how long a rotary cutter blade should last. For example, if you’re only using your rotary cutter once or twice per week then expect to get at least two years out of each blade before needing replacement.

If instead, you’re using your rotary cutter several times per day on heavy-duty projects like fabric then one year might be more realistic.

How Often Should You Change Your Rotary Cutter Blade?

How often you need to change your rotary cutter blades depends on how often you use them. Most professionals recommend changing the blade at least once a year, but if you’re an amateur with limited sewing experience, then it’s probably fine to wait until the blade starts to get dull before changing it.

How do you know when your rotary cutter blade is too dull? If you’re making precise cuts and they come out jagged or uneven, it may be time for a new one. If there’s excessive friction while cutting fabric (which can make sewing uncomfortable), that’s also a sign that it’s time for a new blade. It might sound like an obvious tip, but always use sharp scissors when cutting the fabric.

Changing out your blades is simple; just follow these steps:

  • To start with, turn the machine off and unplug it from its power source so there aren’t any accidents. You should also remove any attachments from your machine so that nothing gets in the way of changing out those blades safely later on.
  • Next up comes removing each individual piece from inside each part of your machine before being able to access anything else inside.
  • From here on out all we have left is unscrewing whatever screws hold our old rotary cutter together within both halves of its housing unit where most models are kept safe within these two pieces so as not

What Can You Do to Avoid Dulling Your Rotary Cutter?

Your rotary cutter is a precision instrument, and as such, it needs to be treated with care. Here are some tips for using your rotary cutter safely:

  • Use the right blade for the job: Don’t use a small blade to cut fabric and then try cutting thick cardboard with the same blade. It will dull quickly and need replacing. The same goes for the size of the project; if you’re making one small quilt block with no seams, don’t use a larger-sized blade; instead, opt for something more appropriate for that particular task.
  • Use the right speed: If you’re using large blades in small projects or vice versa, try slowing down your speed (or increasing pressure). Sometimes this can help prevent any accidents or injuries from occurring while cutting.


Now that you know how long rotary cutter blades last, what factors wear them down, and how often you should change them, it’s time to get back to work.
