The stopper knot is very handy in several situations. For instance you could tie one in the end of the rope it stop it unexpectedly passing through the belay/abseil device. Use it to backup your figure eight follow through tie in knot. Two stopper knots are used to make the double fishermans for joining two ropes. To tie a stopper knot in the end of the rope, follow these steps. Step 1: Form a loop. Step 2: Form a second loop behind the first one, as shown. Step...

Also known as the "Alpine Clutch", this knot locks the rope so it can only move in one direction. It can be used, for example, (in combination with other knots), to ascend the rope or as part of a pulley system for hauling loads. If done correctly it works well, however, I'm not a big fan of this knot and have never used it in a real life situation. If the knot really locks up you might need to prise it free with a nut tool. Also when experimenting with it, I've had one carabiner unclip itself. Note, oval carabiners...

This knot has the advantage of being releasable underload. Something that can come in handy for rescue work, among other things. The knot looks scary, but is safe provided you clip both protruding tails. The knot will slip a bit when weighted. Ideally the knot should not be used unweighted. Follow these steps to tie a Mariner's knot:
Step 1: Wrap a loop of accessory cord (or webbing), around an anchored carabiner. Step 2: Wrap the appropriate end of the cord around the other end four...

The slip knot is handy because, as it's name suggests, you can slide it up to adjust the size of the loop. You might use it to sling a horn ("chicken head") of rock for example. Follow these steps to tie a slip knot using a sling:
Step 1: Form a loop in the sling. Step 2: Feed a second loop through the first. Step 3: Work the knot tight and upwards as required until its snug against the thing you are tying off. ...

This knot is useful for both abseiling and belaying. It's advisable to use a pear-shaped locking carabiner, and try to avoid cross-loading it. The knot will "flip" as opposite strands of the rope are pulled, this is normal. To lock the knot, apply the braking hand by moving the slack line parrel with the loaded line. See pictures below:
Figure A: Here you're feeding out slack when belaying, or you're abseiling down. Figure B: To lock the Munter Hitch draw your brake hand up parallel...

This knot is useful in belay set ups among other things, because it's fairly easy to adjust, unlike, for example a figure eight. With a bit of practise it can be tied one handed. Follow these steps: Step 1: Form a loop in the rope. Step 2: Form a second loop in the opposite direction to the first. Click the image above for a closer look. Some people do this by crossing their hands over (like an X), grabbing the rope in each hand and then drawing two loops whilst uncrossing hands again. Step...

The Prusik Knot The good old prusik knot is very, very useful. All you need is a loop of cord which you can make using 6 or 7mm accessory cord and a double fisherman's knot. With one or two prusiks you can ascend a rope, or rig a z-pulley to haul up an injured climber, or backup an abseil. Suffice it to say it's worth learning this gem of a knot. There are numerous variations on the prusik such as the "autoblock", but follow these steps to tie the standard prusik knot: ...

This knot is sometimes used as a "tie-in", to attach the rope to the climber's harness, instead of the standard figure eight follow through. It has the advantage over the figure eight of being easier to untie after the knot has been weighted. However, it has several disadvantages, such as being less simple to visually inspect, and prone to slippage, requiring the addition of a stopper knot to be really secure. It's also considered weaker than the figure eight. Follow these steps to tie a double bowline:...

This is a touchy subject. Opinions vary among climbers as to the best knot to use when joining two ropes together. The figure eight, overhand, & double fishersman's are just three methods. There's many reasons why you'd want to join two ropes together, but perhaps the most obvious one is to allow for a full rope length retrievable abseil. Rethreaded Figure Eight There is more than one way of joining two ropes using a figure eight knot. The method described below is purely the one I prefer. One...
