We call these our "Professional" Series because many Pro Tyers insist on Japanese hooks! These fine hooks are made in the finest factory in Japan that makes fishing hooks. Outstanding bronze finish, finest tempering and hardening process available, which means the ultimate in strength. Chemically Sharpened. (Please note that the descriptions of "Pro" Series hooks on page 57 in our 2011 Catalog is not accurate. Information is our web store is correct.) We used item numbers which would help you easily compare to others. Our hooks, like all H&H products, are satisfaction guaranteed, or your money back! No questions asked.
