Abstract
A wood-cutting method is disclosed using a tool having a cutting part heated by electric current wherein the temperature of the cutting part of the tool, in proximity of the wood, is maintained at a predetermined level. Also disclosed is a wood-cutting tool that has a carrying part and a cutting part in which the cutting part is heated by electric current. The cutting part is blunt and projects beyond the side surfaces of the carrying part. In order that the temperature of the cutting part be maintained at a predetermined level, the tool is provided with a temperature regulator with at least one temperature-sensitive element arranged in thermal communication with the cutting part. The blunt cutting part is formed as a bulbous rigid member selectively coated with an electrically insulative coating that supports a film electric resistance heating element which in turn is covered by an outer protective covering. A heat responsive sensing element, temperature reference and comparator and adjustable electric power control maintain the temperature of the cutting element at a selected level during cutting.
