Knots in ropes

Hi people, hey do any of you guys know if tying and alpine butterfly will weaken a ropes strength?

I will go out on a limb and say that all knots weaken a rope. Some less than others.

so lets say I took a good whipper on a half rope with a few alpine butterflys in it, it would not break?

If I take a whipper with a figure 8 in the rope will I die?

I have just been tying a heap of butterflys in my 1/2 rope and clipping my up it, you can take a few whippers at times doing this. Being a half rope with quite a few knots in it, makes me freak a little at times, how worried should I be. Will a half rope straight up snap on me?

I am for real guys, is this super bad and I should stop now or will this hold?

Any bend in the rope will weaken the rope
Butterfly knot reduces strength of rope to 75% - according to this source

More rigorous testing can be found here, they quote 70.8%+-3.2% for dynamic ropes, and 80.6%+1.6% for static. Discrepancy can probably be explained by difference in diameter and construction

thanks for the info guys, but I am traveling and have no climbing parners and only my half rope.

come on locker, give me a better way to do it without having to spend two hundy on a little stupid rope eating traxon.

Take your life into your OWN hands. Go free solo something, we're all gonna die. The lucky ones do it on their own terms.

There are also many other devices that can be used for the same purpose that you can pick up cheap on EBAY and HERE and in the back seat of that idiots car with all the climbing stickers on it (Not suggesting you rip anyone off. "Just saying"). PS... I personally value my life more than $200.00. (Like $200.01 for instance) But to each their own!

I like having the rope kinda free so I can climb all ove the place.

<- wonders if a new charity thread for another rope solo device is coming...
