The Trident loop is a fixed loop knot. It can jam when heavily loaded. It was proposed as a replacement for the Figure-of-eight loop for use in climbing by Robert M. Wolfe, MD, who developed it as a loop form of Ashley's bend. While some tests indicate its strength lies somewhere between the weaker Bowline and stronger Figure-of-eight loop, the Trident loop shows exceptional resistance to slipping in shock-loading tests.〔Geoffrey Budworth, ''The Complete Book of Knots'' (London: Octopus, 1997), 94.〕 ==Tying== Image:TridentLoop01.jpg|1. Start with a rope end. Image:TridentLoop01.1.jpg|2. Start an overhand knot, leaving enough rope for the loop and the rest of the knot. Image:TridentLoop01.2.jpg|3. Complete the overhand knot. Image:TridentLoop02.jpg|4. Form the loop by wrapping the working end around, and then form a bight in the working end. Image:TridentLoop03.jpg|5. Feed the bight ''through'' the overhand knot.

This is the completed loop. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trident loop」の詳細全文を読む スポンサード リンク
