Abstract
A folding knife including the combination of a blade sandwiched between a pair of bolsters which are connected to a handle and a pivot pin extending between the bolsters and through an end of the blade. The forward edge of each bolster has a surface of an arcuate configuration and the confronting rearward end of the blade has a surface of an arcuate configuration substantially similar to that of the bolsters to permit the blade and bolsters to meet in sliding engagement when the blade is in an opened or closed position. The knife is particularly useful for activities such as hunting or fishing.
