There are several knots you can choose from to create a loop. Two common ones are the bowline and the Figure 8 on a bight. In rescue and climbing tasks, we want maximum strength, ease in tying and untying, and of course simplicity. Under numerous tests, the Figure 8 knot is always stronger than the bowline (check out this knot strength article). The Figure 8 is also easy to identify when you have tied it correctly. Finally, the bowline can be very difficult to untie after significant load has been placed on the standing end. The basic Figure 8 can be used to make a loop, form a stopper knot, and prevent frayed ends of ropes from unraveling. It is no wonder this knot is the first choice for professional rescue personnel and climbers. Here are some variations with demonstrations:

• The Basic Figure 8
• Figure 8 on a Bight This no more than bending the rope and simply tieing a basic figure 8 knot
