What to Look for While Buying a Rotary Blade Sharpener?

Rotary blade sharpeners are very simple tools, but they can be quite important when you are in the middle of a project and your rotary blade becomes dull.

 Although all rotary blades are almost the same in all aspects, there are some features you need to look for in the one you buy.

1. Size

Most rotary blade sharpeners are small, but there are also some variants in them. The sharpeners that work on electricity are slightly larger than the manual ones.

 Even among the manual rotary blade sharpeners, there are some that aren’t much larger than the blades themselves.

Among the list above, the largest rotary blade sharpener is the TrueSharp 2 Rotary Blade Sharpener, which is built like a machine whereas there are some that aren’t much larger than the blades used in them to sharpen.

2. Operation Process

When it comes to operating the sharpeners, there are two types available: manual and electricity-based. Of course, the ones that run on electricity are much faster than the manual ones, and they cost more as well.

The manual ones are small and simple; usually, you have to place the rotary blade inside the sharpener and close the lid.

 Then, with your hands, the cover lid of the sharpener needs to be twisted and turned for the blade inside to be manually sharpened. The TrueCut TrueSharp Linear Sharpener Notion, on the other hand, is a different kind of rotary blade sharpener.

 It is long and linear, with two pieces of sharpening stones in the middle. The rotary blade needs to be placed inside the sharpener and rolled, just like when cutting fabric.

Electrical rotary blade sharpeners, like the TrueCut TrueSharp Power Sharpener, need the blade to be placed inside the sharpener and the lid to be closed.

With just a push of a button, the sharpener will start to work and the blades will be automatically sharpened.

3. Versatility

Some rotary blades, like the Omnigrid Rotary Cutter Dual Sharpener, can be used to sharpen only blades that are 28mm in diameter. This is a small and affordable rotary blade sharpener, but not one that is very versatile.

On the other hand, most other sharpeners can be used for blades that are 28mm, 45mm and 60mm in diameter.

The more versatile these sharpeners are, the more you can use them to sharpen all kinds of blades you have in your collection.

4.Safety

With most sharpeners, you need to remove the rotary blade from the rotary cutter and then place them inside the sharpener.

 Since rotary blades are always extremely sharp, especially after they have been sharpened, this is not a very easy operation.

 In fact, it is quite dangerous to handle the blades with our hands without any protective gear.

With the TrueCut TrueSharp Linear Sharpener Notion, you won’t have to remove the blade from the rotary cutter.

 In fact, this is an extremely easy process where the rotary blade has to be rolled between the sharpening stones placed inside the sharpener, while still in the cutter.

This makes it possible to sharpen your dull rotary blades at any moment, even when you are in the middle of a project and sing your rotary cutter at that time.

With the Quilting Bear Premium Universal Rotary Blade Sharpener, you get a magnetic stick with the set. With the use of this magnetic stick, you won’t have to use your hands to handle the blade.

The magnetic stick will hold on to the blade fast and you won’t have to risk your fingers both when using the dull and the newly sharpened blade.

These are the special and important features that need to be present in your rotary blade sharpener when you are choosing the right one for yourself.
