Knottology replaces the typical plastic or metal clasp with dual-function Expedition Clasps. Not only does each metal clasp secure the bracelet around your wrist, but it adds a second survival-based function.
Expedition Clasps come in four different varieties. The Guardian clasp includes a small storage compartment that can be used for items like iodine water purification tablets, pills or flint. The compartment can hold up to five iodine tablets, equating to 96 ounces (2.8 L) of clean water. The Navigator has a small compass; the Illuminator has a 15-lumen mini-flashlight; and the Banshee has an integrated emergency whistle that wails out a screech of up to 100 decibels.
Knottology bracelets come in a variety of styles and can be equipped with any of the aforementioned clasps. Knottology offers premade bracelets and do-it-yourself kits with 8 to 20 feet (2.4 to 6.1 meters) of paracord and instructions on how to put the bracelet together.
Knottologoy's multi-functional bracelets make sense – why not get extra performance out of something you're wearing anyway – but they're not the only multi-functional paracord bracelets around. Last year we took a look at a flint-knife bracelet from Bison Designs.
