The traditional armbinder is one of the sexiest rope ties possible. It can be challenging to implement if you don't have a bottom who can naturally touch her elbows behind their back. Having an assistant handy to help hold arms close together when trying this tie for the first time is a good idea. Also, make sure your bottom has thoroughly stretched before attempting this tie to prevent any muscle or tendon damage and please don't force it past his or her ability to endure.

The futomomo has gained popularity as a leg tie over the last couple of years. The "fat leg" tie is so named because it compresses the skin and makes the flesh bulge out around the rope. The futomomo is relatively simple and quick to tie and looks impressive when it's completed.
The Somerville Bowline was devised by Topologist. There have been a lot of methods posted on how to tie this knot due to its instant popularity in the rope scene. There are a lot of similarities between this and the French/Portugese bowline that was my primary cuff for some years. This new cuff is just as easy to tie and has some benefits which have caused it to become my primary single column cuff. Take the time to practice this knot over and over again until you can do it with muscle memory alone.
