Night Ize Figure 9 Rope Tightener (Outdoor Retailer Summer Market 2006)

When your taught-line hitch starts to slip after the cord is rain soaked (or frozen), or your fingers are too cold to hold that slippery spectra cord, or it's too dark to even see the cord at all, line tensioners start to make a lot of sense. The Figure 9 Rope Tightener by Nite Ize is the most cleverly designed tensioning device I've seen yet. Its flexible design with no moving parts works in several configurations to keep your cords secure.
