If you compare the two, you'll see what I mean. These hooks can be found in aluminum, steel or plastic. These are great for multiple strand projects. I enjoy my Boye plastic N hook as well. It is shorter than the Bates and works better for some projects.
Most people become either rounded or inline users.
Inox - This is my personal favorite for daily crocheting. I like the all grey aluminum ones. They seem to just glide through my work. I have been unable to find the original Inox hooks lately. I believe they are now being manufactured under the Prym label but I am not certain about this.
