Pacific Northwest Halibut Fishing Hook

The halibut fishing hooks used by Pacific Northwest (PNW) Native Americans do not have a single originator, but they are an exceptional object developed over time to solve a number of problems at once.

First,  even though they are designed to land fish between 20 and 100 pounds, they can be manufactured by hand carving, without the use of metal knives. PNW Native Americans did not generally use iron tools, but had stone axes, chisels, and knives which they used to work the wooden parts of the hook. When metal tools became available they were quickly adopted. The hooks were made from multiple types of wood chosen for their properties, like strength, density, hardness, and even scent.

Second, the hooks were made in quantity, and repeatably, though PNW Native Americans did not have formalized units of measurement (inches, meters, cubits, etc). Instead, the measurements for the hook were derived from the hands of the carver.

Lastly, and most interestingly, the hooks are designed to only catch fish which are of a decent size, but not large enough that they are of a significant breeding age. Small fish cannot swallow the large hook, while larger fish would gulp the whole hook, then let it slip out of their mouth without it setting. This was recently proven out by a study examining the size of hooks over time, and testing what size fish they could catch. This capacity for discrimination allowed PNW fisheries to avoid overfishing in spite of heavy fishing by skilled fishers with superior technology.

From a design perspective, it is hard not to be impressed with a tool which has such sophisticated functional performance, while being manufacturable at scale, with minimal tooling, and using locally sourced, renewable materials. As is evidenced by the beautiful figural decoration of these hooks, their producers also felt that they were something special.
