These are replacement blades for the X-ACTO swivel head utility knife. they come 3 to a pack and are simple to replace. To replace or remove blades from knife simply unscrew top like any other X-acto Knife and drop in the blade and rescrew locking nut, its that simple. They do last long time and i do sharpen mine on diamond stone. must have item for arts ,crafts,cutting out stencils.
