ABSTRACT:
A knife of a pencil type includes a barrel or outer member in which a slidably carried support or inner member is connected in an end-to-end relation with a blade assembly for movement of the blade assembly to extended and retracted positions relative to one end of the barrel member. The blade assembly includes tension fingers that extend from a lower portion of the blade assembly periphery to engage the barrel member and bias such member in an upward direction thereby preventing side-to-side play of the blade assembly in the barrel member and to inhibit upward movement of the blade assembly therein. The blade assembly is also formed with a slight bow to urge the upper portion of the blade assembly against the barrel member and thereby prevent undesired upward movement of the blade assembly when a cutting operation is performed.
