Similar Knots

Double Fisherman’s Bend vs. Triple Surgeon’s Knot (Bend)

• Pros: Extremely secure for permanent joins, popular in climbing.
• Cons: Harder to untie and bulkier than the Triple Surgeon’s Knot.

Blood Knot vs. Triple Surgeon’s Knot (Bend)

• Pros: Sleeker profile, ideal for fine fishing line connections.
• Cons: More complex to tie and less effective with mismatched line diameters.

History

The Triple Surgeon’s Knot (Bend), a variation of the Surgeon’s Knot, likely originated in medical contexts where surgeons used multiple wraps to tie sutures securely. Referenced in The Ashley Book of Knots (#1209) as part of the Surgeon’s Knot family, its adaptation for fishing and utility tasks highlights its simplicity and strength. Its popularity in angling stems from its ease of tying in wet or slippery conditions, making it a staple for joining lines.

Security Level

The Triple Surgeon’s Knot (Bend) is highly reliable for joining lines of similar diameter, particularly in fishing, with its three wraps providing superior strength over the Double Surgeon’s Knot. It holds exceptionally well under moderate to heavy tension but may jam tightly or slip with significantly mismatched lines. For critical applications, test the knot thoroughly and trim tag ends carefully to prevent unraveling.

Downsides

• Bulky profile: Larger than sleeker knots like the Blood Knot, less ideal for fine lines.
• Jamming risk: Difficult to untie after heavy loads, especially with thin or slick lines.

Structure

1. Lay the ends of the two lines parallel, overlapping by several inches.
2. Treat both lines as one and tie a triple overhand knot by looping the ends around the standing parts three times.
3. Pass the ends through the loop again for a third wrap, creating a total of six wraps (three per side).
4. Pull all four ends (two standing parts and two working ends) to tighten the knot evenly.
5. Trim the tag ends close to the knot for a neat finish, ensuring no slippage.

Pro Tip: Wet the knot before tightening to reduce friction and ensure a snug fit.

FAQ

Is the Triple Surgeon’s Knot (Bend) strong enough for heavy loads?

Yes, it’s reliable for moderate to heavy loads in fishing or utility tasks, but test with heavy loads first.
