In the little world of fish hook collecting mechanical fish hooks are well known and highly sought out. Outside though, most have never seen or heard of them. They are fascinating bits of fishing history. Countless designs for these hooks have been made and patented over the years. Some are highly complex and almost machinelike. Others are very simple yet ingenious fish hooks. Outlawed now, they once were used by serious meat hunters. I have no idea how effective all were in practical terms but I can tell you that some of the ones I have and have seen are tricky just to set so I can imagine when all worked perfectly, they would keep a fish from breaking off.
I have very few of these devises and none of the high ticket ones so most of the hooks shown here will be from other collections and will be identified as such.
I am confident that even non collectors will find this section fascinating.
