  • Patent number: 4967475
    Abstract: An improved all-way offset snips with full width wire cutter has bosses through which first and second blade members are pivotably connected for rotation about an axis perpendicular to the pivot bosses. The blade members have extended offset cutting surfaces with respect to the pivot bosses to permit the cutting of irregular shapes, particularly sharp curves and especially small circles, including opposing circles of about 2.0" to 2.5" diameters. The cutting surfaces are rotatable between an open position and a closed position for cutting the sheet material therebetween. The pivot bosses and the cutting surfaces are adapted for removal of material therefrom to permit resharpening of the offset snips while maintaining the offset of the cutting surfaces. The shanks of the blade members are also provided with wire cutting means, preferably a pinch cutter capable of being a limit stop for limiting rotation of the first and second blade members.

  • Patent number: 4463497
    Abstract: First and second blade members have pivot bosses through which the blade members are pivotably connected for rotation about an axis perpendicular to the pivot bosses. The blade members have cutting surfaces offset with respect to the pivot bosses to permit previously cut material to pass the blade members without interference. The cutting surfaces are rotatable between an open position and a closed position for cutting the sheet material therebetween. The pivot bosses and the cutting surfaces are adapted for removal of material therefrom to permit resharpening of the offset snips while maintaining the offset of the cutting surfaces. One of the blade members may include a recess to permit cutting of both left-hand and right-hand curves. Integral wire cutting means, integral locking means, and an improved handle configuration are also provided.
