A rotary cutter is a really useful tool. I use mine all the time for cutting easy projects such as little make up bags or scrunchies. They are also useful for cutting stretch fabrics when garment making. The blades are very easy to replace. This cutter takes standard size 45mm blades. The blade automatically retracts when not in use and there's a handy button to adjust the cutting depth for bulkier fabrics. The handle is nice and soft and to top it all they look good too!
