Abstract
A utility knife has a flat blade formed with at least one throughgoing hole, a housing member forming a seat adapted to receive the blade, and a retainer member engageable with the blade on the seat. A pair of respective pivot elements on the housing and retainer members allow pivoting of the retainer member between a closed position engaging the blade and holding it against the seat and an open position exposing the blade and permitting its removal from the seat. Respective threadedly interengageable holding elements including a threaded screw on one of the members extending through the hole of the blade and a nut on the other of the members secure the retainer member in the closed position. The threaded screw is fixed in the housing member and has a threaded shaft projecting up from the seat. The nut is rotatable on the retainer member. The retainer member is formed with a large-diameter recess receiving the nut with radial play.
