Looking for an internet site that shows how to tie certain knots. I am particularly interested in a knot called the "Ranier knot"
or something close to that. It is a slip knot that gets tight when there is load bearing but loosens up easily. Thanks, Al.

Never heard of it, and no luck on internet search.

However, there are a lot of knots available on the net. Just use www.dogpile.com which is a parallel search engine; it runs a whole bunch of search engines simultaneously, and then gives you the results all at once, so you can skip over the ones which didn't find anything.

Here is one of the better sites:

The real answer to your question depends upon how much load there is to be on the knot, the direction of the load, and how long you wish it to stay tied. One knot which might serve your purpose is this one:

Hope this helps, Walt

Try this site for some overkill on knots and knot tying:
http://www.earlham.edu/~peters/knotlink.htm

Regarding the 'ranier' knot- nothing in any of my knot books under that name. You may be thinking of the mariner or mariner's knot. This is a specialized knot for releasing a load while under tension, and is used in rope rescue work. Do a search on either mariner or mariner's knot and you'll find it.

Did you have a specific task or purpose in mind for this knot? Just curious. If you're looking for a knot that's easy to untie after it's been put under a strain, try toggling your favorite knot. All you do is insert some kind of rod (the toggle) thru the 'flat' side or 'edge' of the knot before you draw it tight. Make sure it comes out the other side. The toggle can be a screwdriver or even a big nail- I like to use a small, open end wrench. The knot gets tight, but afterwards you grab one end of the toggle and twist it and work it back and forth to loosen the knot from the inside.

Good luck

Good link, Bill!!

Al; check Bill's site and look for 'exploding knots' these are hitches which can be quickly untied by pulling on the non load bearing end of the rope.

Do a web search for "prusick". It's a knot commonly used as a climbing aid: it's basically a loop of small dia. rope looped around a run of a larger rope. It locks onto the large rope when the small loop is put under tension, and releases then the tension is removed. "Ranier knot"? Sounds like climbing to me.

Not to be a smartass or anything, but it's "prussik". Otherwise your search might lead to different results.

Though, I notice that "Lofty" Wiseman spells it "prusik" in the SAS manual, FWIW.

Damn, Jeff, foiled again!

I haven't used jumars in years. When I first learned to climb in the early 70's we'd use a prussik on rappels just in case.

It's funny, I was going through the SAS book the other day to see just how many knots I remembered, and how many needed a little brushing up. I surprised myself that many of them were still second nature.

Thanks guys, the knot I am looking for is used on a tree stand climbing/safety harness and is used to adjust the length of the rope that goes around the tree. A tautline hitch is probably close but the knot has to be secure when it is loaded and unloaded while one climbs up. The harness is similar to those used by utility pole linemen.

Blues,

I use a prusik in conjunction with a rescue pulley for doing hauls and belay systems. It works real well and self holds the rope and automatically releases as you advance the rope....a trick I learned working with cave rescuers. Once rigged right it does not need anyone to man it. I've also used prusiks as safeties for ascending and rapelling as you suggested.

About the only other knot I use is a figure 8. This knot is multi purposed...it can be tied on a bight of rope to attach your harness D ring, tied in the rope then do a follow through and dress with the rope tail to tie off around a tree...its uses are endless. It's easy as hell to tie and also very strong. It's just about replaced the bowline for most mountaineering applications.
About the only thing it's not good for is a midline...I use a butterfly knot for that.

Rubys in 10 sounds good....

Agree on the figure eight...

...And another all time favorite...the Clove Hitch...Never ceases to amaze me how many applications it has.

All this talk is getting me antsy for an outing.

There is a knot(climbing) taught and used in Europe that is not used or taught in the States due to safety reasons. I can not remember the name but it is a knot to set up an anchor for a rappel, as long as you maintain constant and equal tension on both ends of the rope,no problems, once you are down a good whip of the two ropes sends sends a shock/slack to the knot and down comes your rope. If this slack and/or shock should happen while you are still on rappel you day has gone from whatever to realy bad. This is about the only "explosive" knot I've heard of...hope this helped

Sounds a lot like what we use to call a suicide hook. Basically an open end hook that was used as your anchor with a smaller rope or cord attached to the top of the hook. You rapel down the mainline wich is attached to the bottom of the hook, then pull the small cord to release the hook from whatever you had it hooked in to. These were fine on single pitch rapels where you don't stop half way down, but could be deadly if you took the weight off of them before you reached the bottom. Personally, I like an oak tree about 2 feet in diameter with a double 1 inch tubular webbing encircling it with a nice screw gate D ring holding the figure 8 knot on the mainline - bomb proof.

We taught a rapelling class about 3 weeks ago and had a girl that claimed she had experience. She did a 180 breaking the edge and ended up with her head going down first. I was on the instructor line beside her and my partner was belaying from the bottom. She freaked but managed to regain control and right herself. Due to her unique situation and using an 8 as a rapelling device, we had to go slack in the rope to get everything straightened out for the finish ride down. Any type of rigging that's not bomb proof and dependent on tension as security is no good in my opinion, even with experienced users since unexpected **** does happen.

The knot that the German para is describing is shown in Ashley's Book of Knots. It is extremely dangerous, and is only shown to demonstrate the solution to the problem of descending a cliff, then being able to pull down the rope after you.

Thats probably the one Walts talking about, I didn't rig it my climbing buddy did and gave me alot of warning prior to loading the rope. Then he made his rap and then a good flick of the rope and down it came. Like Jeff I would have set somehting a bit more bombproof and burn whats left at the anchor site, but in a military situation you might not want to leave a trace of your comings and goings. But I must agree with Walts book. Not for your everyday use(if at all).
