The Infini Easycutting line is a set cutting boards that have tiny, laser-etched gutters to guide your crafting knife as you cut out various shapes. The type-B gives you access to squares and triangles of various sizes for cutting out checks or other shapes, and a set of circles for cutting out circular shapes for use on round objects, like cockpits. I've been using the board for a week now and it's been very useful for my miniature and plastic model painting, and exactly what I wanted. I'll probably try to grab one or two other boards. One note, though -- make sure your crafting knife is very sharp at the tip, as any dullness will affect the way the cutting works. In addition, cut carefully -- I've made a few mistakes where my knife has jumped the pathway, and I worry that if that happens enough times I'll lose the ability to cut exact shapes. I'd like to see a board made of something a bit tougher, if they ever do a second set, perhaps ceramics. But as is, I think ruining the board would take a lot of purposeful effort or a very long span of use. in short, highly recommended.

Great item for making more precise cuts for masking fine details to be airbrushed
