OLFA 18mm Rotary Circle Cutter (CMP-3) - Adjustable Rotary Blade Cutter w/Ratchet Handle Cuts Perfect Circles for Crafts, Sewing, Quilting, Replacement Blade: RB18-2

easy to use

I bought this because I needed to cut circles out of 2.6-2.8mm belting leather and trying to do it with a hand cutter was very difficult and gave less than perfect results. I found that, for me, the easiest way to cut something that thick was actually to put the pin in the centre of the section I wanted to cut out, then press down on the cutting blade end and turn the material under the cutter (instead of turning the cutter) and just keep rotating it until there was no resistance which meant I was through. If I had one complaint it's that, although it has notches on the measuring gauge, there's no numbers on the scale, so I had to use a fine marker pen to write in numbers myself, but that's a minor niggle about what is a very handy and useful tool indeed.

EXCELENTE! RECOMENDO. PRINCIPALMENTE PARA QUEM FAZ ARTESANATO.

Watch the video at OLFA webpage where they show how to use it, its easy to use but makes getting started even easier. The blade extends about 2.8mm from the holder, but cutting 3mm soft foam works just fine.

It is using the 18mm rotary cutter blades. If you have one, you saved yourself buying additional blades. If not, these blades are inexpensive and more affordable compared to Olfa COB-1 which is used by other Olfa models or at least here in amazon. Plus, 18mm can be rotated at both directions and can cut through more materials where the ones using COB-1 can be used at single direction. Not only that, this model has ratcheting mechanism where you can rotate without loosing you grip.

I use it for fabrics, works well
