When I don’t tie the clinch, I tie the blood. And the right angle tag ends of a blood knot offer opportunities in rigging: tandem flies with one on the point and one on the blood knot dropper, a nymph on the point with extra weight attached to the dropper, etc.And, like Phil, I admit that a big part of my attachment to the blood knot is aesthetic. The surgeon's knot differs from the square knot due to an extra pass through the loop of the first throw. Plus, I’ve taught fly fishing and fly casting for over 35 years, and I teach the surgeon’s both as a tippet knot and a tie-on-the-fly knot to beginning fly fishers. To tie the Triple Surgeon's Knot, proceed to do a total of three (hence the triple in the name) wraps of the loop through the overhand knot. SURGEON'S KNOT. Also, more throws leads to better knot security. For all sutures, a 0-gauge United States Pharmacopeia size suture was used. I have heard through the grapevine that a triple surgeon’s is a stronger knot, so I usually use that when I’m being lazy, but I am a blood knot man.That said, my opinion is probably moot—but I’ll give it to you anyway. The surgeon’s knot (79.7 N) failed at a slightly lower tension than the square knots (82.9 N), a difference that was not statistically significant.
Surgeon's Knot A surgeon's knot is often used in high-tension tissues that cannot be properly apposed using a square knot. By using the surgeon’s for a tippet and a fly knot, I am able to teach the beginning fly fisher one knot, the surgeon’s, which covers all their on-the-water-knot needs. [1–2] Flat square knots are the gold standard for surgical procedures because they are more secure when there is a risk of tearing a suture through delicate tissue. If one strand cuts across the other as the knot rolls over into the figure 8 as it is tightened, the knot will be quite weak, and it is not due to any error on the part of the angler tying the knot.
Many factors affect knots including: the appropriateness of knots and rope materials used in particular applications, the age, size, and condition of ropes; and the accuracy with which these descriptions have been followed. Therefore, it's helpful to throw the 2nd knot in the same direction (slip knot) to tighten the knot. [1–2] A prior study by Tera et al. Like 9 Pretty much the most basic knot for holding to ends of rope together. The drawback to the surgeon’s is that it uses up more tippet material, and it clearly is not as elegant as the blood knot.The Blood Knot is one of the first “complicated” connections that most fly fishers learn, but it becomes easy to tie with practice and makes a slimmer connection. That principle can be used with any suture type.
