Tying the Double Surgeon Knot

Use the Double Surgeon Knot to connect monofilament of similar or dissimilar sizes. This knot is superior to the more popular blood knot in several ways. Most importantly, it has a stronger breaking strength and is better for joining widely divergent monofilament sizes. It's also a heck of a lot easier to tie than a blood knot.

It is however, a bulkier knot than the blood knot. Consequently, many anglers prefer a blood knot when joining monofilament in the larger diameters (i.e. 2X, 1X, and 0X). The smaller, tapered blood knot will slide through the rod guides easier and knot strength is not an issue in the larger diameters. The Double Surgeons knot is the knot of choice for tying on tippet, where knot strength is critical.
