Dirt. Fibers. Debris. When they invade either part of your Velcro fastener, you have a not-so-sticky situation on your hands. Thankfully, Trip Felton's Hook and Loop Tool keeps everything clear. Simply clean your hooks and loops with the wire or soft brush and make the bond be virtually airtight. Includes a folding boot cleaner and latch to keep the butterfly knife style design closed when you're not using it.
