A “short shank” hook is an interesting tool for a tier. If you tie a standard length pattern on a short shank hook, you select one size larger than normal – a size 12 Adams fits on a size 10 “short shank”. This does two things that may be beneficial. First it gives you one size heavier wire, therefore increased strength. It also gives a wider gape for increased hooking effectiveness. Of course, these hooks are also used for short dry flies, spiders, beetles, ants, etc.
