A reed blade

Abstract

The invention discloses a tool for chopping reeds into slices, and particularly relates to a scraping knife for only chopping a reed into one slice. The reed scraping knife consists of a knife point, a knife edge, a knife back and a knife handle. The reed scraping knife is characterized in that the knife point is arranged at the front end of the reed scraping knife; the direction of the knife point is perpendicular to the knife back; the outer side of the knife edge is in the shape of a triangular pyramidal wedge; an inclined knife edge is arranged at the inner side of the knife point; the middle section of the reed scraping knife is a straight knife edge; a transition section between the inclined knife edge and the straight knife edge is a sunken circular-arc knife edge; a knife surface section which corresponds to the sunken circular-arc knife edge is a think knife surface which is sunken inwards; the knife back of the sharp knife edge is transited from a 4mm thick part at the front end to a 1.5-2mm thick part of the knife back corresponding to the circular-arc knife edge; the 4mm thick knife back corresponds to the straight knife edge; and the knife handle is arranged at the tail end of the reed scraping knife. The scraping knife can chop a reed with a relatively small diameter of 6-8 mm into one reed strip with width equal to perimeter for knitting, and therefore, a resource utilization rate is increased by the scraping knife, and resource waste is reduced.

Description

technical field [0001] The invention is a tool for splitting reeds into slices, in particular a bamboo knife for splitting a reed into slices. Background technique [0002] At present, the shape of the reed strip knife and the bamboo strip knife is basically the same, both are long straight blade, thick knife back, and round handle, but the size is smaller. The diameter of the root end is split with a knife, and a reed is divided into two parts from the root end to the tip end. After being crushed and softened by stone rollers, it becomes a reed strip, which can be used for reed weaving. When the diameter of the reed is thinner, less than 8mm, when the thinner reed is split into two narrow reed strips for weaving, the weaving efficiency is low. Therefore, at present, the thinner reed with a diameter of 6-8mm It is discarded and discarded, so it is a waste of data. At present, the reed strip knife used cannot split a reed into only one piece of reed strip. Contents of the...

Problems solved by technology

When the diameter of the reed is thinner, less than 8mm, when the thinner reed is split into two narrow reed strips for weaving, the weaving efficiency is low. Therefore, at present, the thinner reed with a diameter of 6-8mm Eliminated and discarded, thus a waste of data

At present, the reed strip knife used cannot split a reed into a piece of reed strip
