The Turle Knot, also called a Turtle Knot, is not suitable for straight-eyed hooks. It is a specialized knot that attaches the leader to off-set eyed flies (down or up), for a straight pull.
To Tie a Turle Knot:
| Pass the tag end through the eye and loop it around the shank of the hook, finishing off with an overhand knot. |  |
| Double the overhand knot for an improved Turle Knot. |  |
| Use a round turn for a double Turle Knot. |  |
