Electrical knife Electric knife is a cutting tool commonly used by rural electricians. Ordinary electric knife consists of blades, blades, knife handles, knife hangers, etc. When not in use, shrink the blade into the handle.

When using an electric knife to cut the insulation of the wire, slightly raise the knife and use the rounded corners of the knife edge against the wire core. Do not cut the insulation perpendicular to the wire perpendicular to the blade, as it is easy to cut the wire core.

The insulation on the wire should be stripped before the wire connection. When cutting with an electric knife, do not hurt the core. The commonly used methods of exploitation include flaking and beveling.

The edge of the electrician's knife must be sharply polished to remove the wire, but not too sharp, too sharp and easy to cut the core, and wear it too blunt, then it is impossible to insulate the insulating layer and sharpen the edge. Usually, sharpening stones or grindstones are used. After grinding, the bottom of the grinding point is chamfered, that is, the edge is slightly rounded to exploit the outer insulation of the double-core sheathed wire, and the edge of the two-core wire can be aligned with the cutting edge, and the wire is cut into two.

In order to cut the groove between the log and the wooden slot or the plastic slot, an electrical knife can be used to cut at the construction site. Usually, the round wood is supported with the left hand and the knife is cut with the right hand.

Electric knives can be used to cut rafts and bamboo rafts.

In addition to the blades, the multi-function electrician's knife also includes saw blades, awls, and reaming cones.
