Snap Hooks allow you to change flies rapidly when searching for the pattern fish will hit. They also provide a "loose" connection that gives the fly a bit more movement behind an Action Disc. These are made from hook steel and have a bend open strength of 21.5 (Large) and 40 pounds (X-Large). I recommend Large for hooks up to #1 and the X-Large for hooks 1/0 and larger.
The "Fas Snap" brand hooks are nickel plated, made in the USA. Sold in packages containing 5 pieces.
Mighty Mini Crane Swivels
Mighty-Mini Crane Swivels are 100% spring tempered stainless steel and are up to 3X stronger than brass crane swivels of the same size. These #14 swivel have a break strength of 78#. They are the smallest on the market and can be wound up through most rod guides. The stainless feature will prevent corrosion in alkali lakes such as Pyramid Lake Nevada or in salt water. This is the swivel I use to join two different size leader pieces on my "Top-Line" trolling lines. Also a good choice for joining braid to monofilament.
A great product to add to your tackle for a number of applications.
