Components of Double Clinch Knot

Standing Line

The standing line refers to the mainline portion of the fishing line that remains unaltered throughout the tying process. In the Double Clinch Knot, the standing line plays a crucial role in providing overall strength to the knot. It’s essential to maintain a firm grip on the standing line while feeding the tag end through loops for a secure and tight knot.

Tag End

The tag end is the working part of the fishing line that is used to create the Double Clinch Knot. To tie the knot, one must first start by passing the tag end through the hook eye. The next step is to wrap the tag end around the standing line several times, creating a series of loops. Finally, the tag end is passed through these loops and then pulled tight to secure the knot. The excess tag end can be trimmed for a neat finishing touch.

Hook Eye

The hook eye is the small opening in the fishing hook where the fishing line is threaded. When tying the Double Clinch Knot, the tag end is passed through the hook eye as the initial step. Proper alignment of the hook eye is essential to maintain the knot’s strength and overall functionality.


Creating loops is a key component in tying the Double Clinch Knot. Loops are formed by wrapping the tag end around the standing line multiple times. The number of loops can vary depending on the thickness and material of the fishing line. Generally, 4-6 wraps are recommended for thinner lines, while 2-3 wraps may suffice for thicker lines. Once the desired number of loops is formed, the tag end is carefully passed through these loops and pulled tight for a secure and effective knot.

Step-by-Step Instructions

The Double Clinch Knot is a versatile, time-tested, and popular fishing knot used for attaching hooks, rings, and swivels. It offers reliable knot strength, typically around 90%. To tie this knot effectively, follow these steps:

  1. Make a long bight in the working end of the line: Begin with a long bight, with around three inches of the double line pulled through the hook eye.
  2. Wrap the double tag end: Take the double tag end and wrap it five times around the doubled standing part of the line. With slick braided lines, 10 to 15 wraps are recommended to prevent the knot from slipping.
  3. Tighten and trim: Once the wraps are complete, tighten the knot securely. Use a pair of scissors or a knife to trim the excess line.

Comparison to Other Knots

In this section, we will compare the Double Clinch Knot to other knots, specifically the Clinch Knot and the Improved Clinch Knot. These knots are commonly used in fishing for attaching lines to hooks, lures, or swivels.

Clinch Knot

The Clinch Knot is a simple and effective knot for attaching a line to a hook or lure. It is formed by threading the line through the eye of the hook, then wrapping it around the standing line several times (typically 5 to 7 times), and finally threading the tag end back through the loop formed near the eye of the hook. The knot is then tightened by pulling on the standing line. However, its simplicity comes at a cost:

  • The Clinch Knot struggles with some types of fishing line, particularly with braided line, as it can slip and risk losing the fish.
  • It has a moderate knot strength, usually around 80% of the line’s breaking strength.

Improved Clinch Knot

The Improved Clinch Knot is a popular upgrade over the basic Clinch Knot. Like the Clinch Knot, it begins with threading the line through the eye of the hook, wrapping it around the standing line several times, and threading the tag end back through the loop near the hook’s eye. The added step is to thread the tag end back through the larger loop that has just been created, resulting in a more secure knot.

The Improved Clinch Knot offers several advantages over the standard Clinch Knot:

  • The added step increases the knot’s strength, resulting in a breaking strength of around 95% or better for up to 50-pound test lines.
  • It is more secure and reliable, as it is less likely to slip.
  • It works better with a wider variety of line types, including monofilament, fluorocarbon, and braided lines.

In conclusion, the Double Clinch Knot is effective in maintaining high strength and is especially useful for targeting larger fish with smaller-diameter lines. Although the basic Clinch Knot is reliable for specific applications, the Improved Clinch Knot offers higher knot strength and versatility.

Best Applications

Fishing with Braided Lines

The Double Clinch Knot is an excellent choice for anglers who use braided lines. This knot is particularly effective due to its high strength and reliability when it comes to attaching hooks, rings, and swivels. With a knot strength of 90%, the Double Improved Clinch Knot is perfect for handling the tension that comes with reeling in a fish.

Braided lines, known for their minimal stretch and slick surface, can sometimes cause knots to slip. The Double Clinch Knot’s strong grip can help prevent slippage. Some anglers recommend using 10 to 15 wraps with braided lines to ensure the knot stays secure.

Moreover, the Double Clinch Knot is versatile and suitable for multiple fishing situations. It can be used with various fishing lines, including mono-filament and fluorocarbon leaders. This adaptability makes it a valuable addition to any angler’s repertoire.

To summarize, the Double Clinch Knot is a practical choice when fishing with braided lines due to the following factors:

  • High knot strength (90%)
  • Reduced risk of slippage on slick braided lines
  • Adaptability for use with different types of fishing lines and leaders

This section has discussed the best applications of the Double Clinch Knot, with a focus on its compatibility with braided fishing lines. Its impressive strength and versatility make it a valuable knot for anglers to learn and utilize in various fishing situations.

Knot Strength and Performance

The Double Improved Clinch Knot is known for its reliability and high knot strength. It is particularly useful for attaching hooks, rings, and swivels, and provides an effective solution for anglers targeting bigger fish with smaller-diameter lines.

  • Knot strength: Research suggests that the breaking strength of the standard Improved Clinch Knot is already considered to be 95% or better for up to 50-pound test, making it a strong choice for most fishing applications.

By doubling the line to create a Double Improved Clinch Knot, further strength can be added to the connection. This is especially helpful when fishing for larger species or employing thinner lines.

The Double Improved Clinch Knot can be compared to other fishing knots in terms of strength and application:

  • Palomar knot: A more powerful knot that is well-suited for braided lines.
  • Uni Knot: Known for being stronger and maintaining more tippet breaking strength, making it a popular choice for fly fishing.

In terms of knot strength testing, the custom machine built by Berkley is often used. Here’s a reference to the line types and their pound tests used in these tests:

  • Monofilament: 15-pound Trilene monofilament
  • Fluorocarbon: 15-pound Berkley Professional Grade 100% fluorocarbon
  • Braid: 14-pound Berkley Fireline braid

These tests help provide accurate measurements for the strength of various fishing knots, giving anglers a clear understanding of each knot’s performance and potential applications. It is essential for anglers to choose the appropriate knot based on their desired outcome, line type, and targeted species to ensure optimal performance and success in catching fish.
