I bought the curve shear, and I love it. Its very sharp. I've had it for over a year now and its still crazy sharp! I am a curl specialist, so dry cutting curly hair is all I do, and this shear is absolutely best for the job! It doesn't push the hair like some shears will do. Its comfortable in my hands, and I love the how it can help with detailing and precision cutting. I did try it on someone with wavy/straight hair, I do like how easy it is for slide cutting, and texturizing as well! Its definitely worth it! If your not sure, you wont regret! I bought mine on a black Friday special and I'm so glad I did.
