I, who could not wait to get my rotary cutter for my sewing .... I was very disappointed! The cutter is really bad, it almost cut anything. We must go after it like a brute to hope to cut something ..... The tissue was however very end! I regret my purchase! I'll have to buy a new cutter since this one sucks! With respect to bias devices, they are correct. Just take the hand. Delivery was super fast, the package was well packed
