The BL354 is primarily designed for tying wet flies. Hends also offers it for dry flies intended for large fish, when a medium-strength hook is preferred over a very fine model.
Barbless and finished in Black Nickel, it is available in sizes #8, #10, #12, #14, #16, #18, and #20. Each packet contains 25 hooks: this allows you to tie a single fly pattern in multiple sizes depending on the target insects and fishing conditions.
