摘要： 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. Also, an improved handle configuration with improved toggle means provides greater power.

摘要： 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.
摘要翻译： 第一和第二叶片构件具有枢转凸起，刀片构件通过该凸起可枢转地连接以围绕垂直于枢轴凸起的轴线旋转。 叶片构件具有相对于枢转凸起偏移的切割表面，以允许预先切割的材料不受干扰地通过叶片构件。 切割表面可以在打开位置和关闭位置之间旋转，以在它们之间切割片材。 枢转凸台和切割表面适于从其中移除材料，以允许偏移剪刀的重新锐化，同时保持切割表面的偏移。 叶片构件中的一个可以包括允许切割左手和右手曲线的凹部。 还提供了整体线切割装置，整体锁定装置和改进的手柄配置。
