Sure you could use a knife to clean the caked dirt and gunk out of the crevices of your shoes. You could also use a knife to clean the caked dirt and gunk out from under your fingernails. But it's probably not the best idea. Not swell for the knife, and with one wrong swipe, potentially disastrous for your arms and fingers. The MudBlade shoe scraper is a foldable blade with a beak-shaped end angled especially for digging into and along the channels and valleys of shoe soles. Use it to get rid of mud, pebbles, dead leaves and all the other not-so-great elements of the great outdoors your shoes pick up on your treks.
The MudBlade features a comfortable, ergonomic grip and can be used on any kind of shoe. Its open end can attach to a carabiner and, in turn, belt loop or zipper.
