Fishing crimps are small metal sleeves that are used to create a secure connection between fishing line and hooks, swivels, or other terminal tackle. They are typically made of brass or stainless steel and come in various sizes and styles, such as oval or double-barrel.

To use a crimp, the fishing line is passed through the sleeve, inserted into the terminal tackle, and then compressed using a special tool, like a crimping pliers or crimper. The compression creates a secure hold on the line, preventing it from slipping or pulling out.

Fishing crimps are popular among anglers because they provide a simple and effective way to connect line and tackle, improving reliability and reducing the risk of losing fish. However, it is important to choose the right size and style for the job, as well as to use a high-quality crimping tool to ensure proper compression and holding strength.
