Editing Knot (section)

===Trick knots===
[[Magic (illusion)|Trick]] knots are knots that are used as part of a [[magic trick]], a [[joke]], or a [[puzzle]]. They are useful for these purposes because they have a deceptive appearance, being easier or more difficult to tie or untie than their appearance would suggest. The easiest trick knot is the [[slip knot]].<ref>Karl Fulves, Joseph K. Schmidt, ''Self-Working Rope Magic: 70 Foolproof Tricks'' (1990), page 17.</ref> Other noted trick knots include:
* [[Grief knot]]. The starkly differing behavior of the knot, depending on how it is arranged, has been exploited as the basis of a [[parlor trick]].<ref name="ashley415">{{citation |last=Ashley |first=Clifford W. |title=The Ashley Book of Knots |year= 1944 |publisher=Doubleday |location=New York |page=415 }}</ref>  When pulling on the standing ends the knot starts slipping and the working ends become crossed. By twisting the working ends so that they uncross and then recross in reverse, the knot's structure capsizes so that it will no longer slip. The twisting motion resembles the turning of a key, "locking" and "unlocking" the knot.
* [[Tom fool's knot]], used as a trick knot due to the speed with which it can be made.
