Double Turle Knot Details
Origin: British Major William Greer Turle popularized the original version in the late 1800s. However, according to some accounts Turle himself did not claim to have invented it.
Early History: Nevertheless, in Modern Improvements in Fishing Tackle and Fish Hooks (1886 Edition P.20) Cholmondeley-Pennell said that "......he had been in the habit of using a very ingenious knot invented by Major Turle, and known under his name. Attached to the turn-down eyed hook it answers excellently well, as I can testify from experience, having used nothing else for many weeks in sea and river fishing."
However, by 2006, his enthusiasm for the Turle had been superseded by the Half-Hitch Jam. In "Fishing. With contributions from other authors. Salmon and trout." he wrote that the Half-Hitch Jam is "...in fact, the knot which I have always used and recommended for a bare hook (in preference to the 'Turle' or any other knot), in consequence of its combined neatness and absolute security from slipping;" (1906 Edition, P.27.)
Variations: With fishing lines then available, the original Turle just employed a simple Slip Knot that was dropped over the Fly. One loop was sufficient, there was no additional knot and the end was not trapped under a knot. Modern slippery lines demand improvements: The Double Turle shown here uses two loops; the loops are held by an Overhand Knot; and, the loops grip the tag end. Some writers add an extra turn to the knot to make a Surgeon's Half Knot, e.g., Mark Bowler.
Purpose: The Turle Knot is used while fishing to tie a hook or fly to a leader.
Other Names: The Turle Knot has also been misnamed the Turtle Knot and the Turrel Knot.
