Abstract: A multi-bladed knife is formed with three parallel blades attached to a handle by means of a screw rod and spring arrangement mounted at front and rear portions of the handle, respectively. The screw rod fastens the blades to the front end of the handle and is rotatable to adjust the transverse spacing between the blades. Application of manual gripping pressure to the rearward portion of the handle against spring bias serves to direct the outer blades into a diverging angle relative to the handle so as to facilitate release of the knife from an object being cut. Release of manual pressure restores the outer blades to their parallel state.
