ABSTRACT:
A knife and knife holder assembly for use with a sheet material cutting machine includes a replaceable knife with a lower most tip point and a guard and clamp member having a shoe surface engagable with the material being cut to limit the knife's penetration. An adjustment means and a connecting means associated with the guard and clamp member and with the holder allow for quick and easy adjustment of the vertical position of the member on the holder to vary the amount by which the knife protrudes beyond the shoe surface, thereby adjusting its penetration, and also allows quick and easy movement of the member between tightened and loosened conditions relative to the holder, the knife being removable from and replacable in the holder and the member being vertically adjustable in its loosened condition, and the guard and clamp member in the tightened condition of the connecting means being itself fixed to the holder and also holding the knife clamped in a fixed position to the holder.
