An alternative to the Pica line of products, however it has nowhere near the same fit and finish in the hand or pocket. Comes in a nice set with an ink marker and lead pencil.

Simple, quick and effective way to cut circles. We’ve had the small model for a while and it has been used extensively. We’ve added this one to be able to cut bigger circles. However if you don’t need the ability to cut really small circles I’d recommend this one over the CMP-1. The rotating handle and rotary blades make it easier to move the tool smoothly.

Note you’re not restricted to making circles with these tools. Used on the edge of a sheet you can make semicircles and using different radiuses you can produce crescents.

There’s not much to say about Olfa blades. They’re sharp and retain their edge for a long time even when cutting materials that tend to dull blades.

One of the best tools I bought. Fastens boards together efficiently and effortlessly, thanks T4 for that wonderful special. I am always on the lookout for such amazing deals

This is almost perfect. It really can cut 1cm circles, and it does so perfectly. The only complaint about this model is that the handle doesn’t rotate which makes it slightly harder to use than it needs to be. Even so we’d buy it again.

There are actually 15 blades in this refill. We use the CMP-1 a lot, but even so a pack of blades will last you a long time as they don’t dull too quickly.

Works terrific with minimal thinning of the paint. Simple to use once the correct volume and spray pattern is selected.
