When it comes to tying a strong, reliable fishing knot, the San Diego Jam Knot stands among the best. Originally developed by tuna fishermen out of San Diego, this knot is prized for its strength, simplicity, and ability to perform under heavy pressure. Whether you’re chasing big game offshore or looking for a dependable connection for any lure or hook, the San Diego Jam Knot should be part of your toolkit.
One of the great things about the San Diego Jam Knot is that it works exceptionally well with both monofilament and fluorocarbon leaders — especially high-quality options like the Shimano Ocea Fluorocarbon Leader. When using premium leader materials, having a knot that preserves strength and offers a clean, compact finish is key — and the San Diego Jam Knot delivers.
Unlike some other knots, the San Diego Jam Knot doesn’t necessarily require lubrication to set properly. It’s a tough, compact knot that holds tight when tied correctly — and it’s surprisingly fast once you get the hang of it.
Why Choose the San Diego Jam Knot?
Strength:
The San Diego Jam Knot is built to perform under extreme pressure. Whether you're fighting powerful fish that make blistering runs or cranking up the drag to turn a fish away from structure, this knot can take the load without slipping or breaking. Its design distributes tension evenly, meaning you can fish with confidence knowing your connection won't fail when it matters most.
Simplicity:
One of the standout features of the San Diego Jam Knot is how easy it is to tie — even in tough conditions. Whether you're on a rocking boat, dealing with cold fingers, or racing the clock as a school of fish comes through, this knot can be tied quickly and reliably. Once you get the steps down, it becomes second nature, making it a go-to knot for both beginner and seasoned anglers.
Compatibility:
The San Diego Jam Knot pairs exceptionally well with a variety of fishing lines, especially fluorocarbon leaders like the Shimano Ocea Fluorocarbon. This is critical because fluorocarbon can be stiffer and less forgiving than monofilament, and not all knots handle it well. The San Diego Jam Knot maintains excellent knot strength, preserving the integrity of premium leader material so you get the best possible performance from your gear.
Compact Profile:
A knot that’s bulky or messy can cause problems — from catching on rod guides to scaring off cautious fish. The San Diego Jam Knot creates a small, neat profile that slides easily through guides and casts smoothly. Its tight, low-profile design also reduces water resistance and visibility underwater, helping you present your bait or lure more naturally to wary fish.
This knot is an essential for any angler, so here’s how to do it.
1. Pinch
Start by threading your line through the eye of the hook, lure, or swivel. Then double it back on itself to form a loop. Pinch the loop and the standing line together just above the hook eye to hold everything steady.
2. Tie Down
Bring the tag end down toward the hook and tie down over the doubled line. This sets up the base for the wraps that will secure the knot.
3. Wrap Loop 4–5 Times
Take the tag end and wrap it around both the standing line and the loop you created. Make 4 to 5 tight wraps, working away from the hook toward the loop’s base. These wraps are the heart of the knot’s strength.
4. Go Back Through the Loop
After finishing the wraps, pass the tag end back through the loop that was created at the hook eye. This helps lock the wraps in place.
5. Go Through the Loop at the Top
Next, feed the tag end through the second loop — the big loop you’ve been pinching at the top. This move ties everything together and sets up the knot for tightening.
6. Grab the Tags and Pull
Hold the hook or lure in one hand and grab the tag end and the standing line with your other hand. Pull steadily and firmly to start tightening the wraps and forming the knot.
7. Grab the Main Line and the Single Line and Slide Down
With the wraps starting to cinch up, grab the mainline and the single line (the standing part that’s not doubled) and slide the knot down toward the eye of the hook. You want the coils to nest tightly without overlapping.
8. Cut the Three Tag Ends
Once the knot is snug against the hook and everything looks neat, trim the three tag ends (the two short sections from the doubled line and the tag end itself) close to the wraps.
If you’re looking for a knot that combines strength, speed, and reliability, the San Diego Jam Knot is one of the best tools you can have in your fishing arsenal. Its straightforward tying method, excellent compatibility with premium leaders like the Shimano Ocea Fluorocarbon, and clean, compact finish make it ideal for a wide range of fishing situations — from inshore battles to offshore big game pursuits.
Mastering this knot not only gives you stronger connections but also builds confidence every time you cast. Take the time to practice it a few times, and soon you’ll be tying it effortlessly — ready to take on whatever the water throws at you.
