Over the weekend I was experimenting with a Becket hitch. I have 1/2" strap CL on the hammock and usually use a Hummingbird style strap/whoopie sling. I used the loop of the " Amsteel whoopie to tie a slippery Becket hitch to the CL. When I got in... it held for a second then flop down I went as the Becket hitch slipped. Thing is when I looked at the knot it was still tied correctly and the tucked tag end was still looped like I tied it. I was not really in the mood to fuss so I just hooked it all up as normal.

But during a particularly long staff meeting today, it started to bug me, how could this thing slip, yet leave the knot tied?
