A knife (10) has a handle (15) with a mount (16) for affixing a removable blade (11). A concave surface (17) of the mount supports an elongate protrusion (18) for engaging a complementary slot (12) in the blade and reaches a landing (20) rearward of the tip that is exposed when the blade is mounted on the handle with a surface of the blade being completely supported by the concave surface. A channel (25) in the landing is dimensioned such that a rearmost part (26) thereof remains exposed when the blade is mounted on the handle. The blade is removed by inserting a curved lever (30) into the channel underneath a rearmost part of the blade and swiveling the lever so as to disengage the blade from the elongate protrusion. |
