Crampons are fastened to footwear by means of a binding system. Improved attachment systems-such as a cam action step-in system similar to a ski binding and particularly well adapted to plastic technical mountaineering boots-have widely increased crampons use.
Sometimes clamps are only used to hold a single object down as it is worked on and then removed. For instance, instead of cutting a 2-inch by 4-inch piece of lumber by propping it up on his or her knee (which is extremely dangerous), a person can clamp the lumber to a work table and keep both hands safely on the saw.
