A surgical instrument comprising: an elongated, generally round handle having a lengthwise extending bore formed in a distal end thereof, said elongated handle having an indented area near said distal end contoured to accommodate a human thumb; an elongated extension member, said extension member having a proximal end adapted for insertion in said bore for removably attaching said extension member to said elongated handle, said elongated extension member having a mounting surface formed adjacent a distal end thereof, a spring loaded push button mounted adjacent said extension member distal end biased for protruding through said mounting surface, said enlarged circular portion formed at the end of said slot away from said proximal end of said blade section, a mounting post protruding from said mounting surface adjacent said extension member distal end disposed in spaced relationship with said spring loaded push button, said mounting post disposed between said spring loaded push button and said extension member distal end, said mounting post having a flattened top forming a radially extending flange, said flange having a larger diameter than said mounting post; and a blade section having first and second apertures formed therethrough disposed in spaced relationship at a proximal end thereof, said first aperture forming a lengthwise extending elongated slot one end of which being an enlarged circular portion having a diameter slightly larger than said mounting post flattened top for receiving said flattened top, said enlarged circular portion formed at the end of said slot away from said proximal end of said blade section, the width of said elongated slot being slightly greater than the diameter of said mounting post, said second aperture adapted for engaging said spring loaded push button and preventing lengthwise movement of said blade section when said proximal end thereof is placed in overlaying relationship with the distal end of said elongated extension member, a lower side of said blade section in contact with said mounting surface, said flattened top protruding through said enlarged circular portion of said elongated slot, and said elongated slot displaced lengthwise for slidingly engaging said mounting post, said radially extending flange engaging said proximal end of said blade section retaining said proximal end of said blade section tightly against said mounting surface of said elongated extension member.
