Description

{KNIFE SUPPORTING APPARATUS}

The present invention relates to a callegric jig device, and more particularly, to a callegric jig device capable of supporting a knife to stably and conveniently polish a knife including a woodcutting knife to a grinding edge of the grinder device.

Generally, a tool such as a chisel is used for finishing, grooving or cutting wood, and these tools require abrasive polishing since the blade is scarce due to the friction occurring during use.

As a typical method for grinding a blunt blade, the blade was tilted against the surface of the grinding stone, and the grinding was performed by rubbing the blade with the front and back.

However, since the slope of the blade contacted with the grinding stone can not be made uniform when the workpiece is polished manually, abrasive defects frequently occur.

Generally, in a jig for polishing a chisel or a blade of a blade, generally, a type in which the angle of the tool is clamped and then the grinding is performed on the grinding stone, and the type in which the angle of the tool is adjusted and the grinding is performed outside the grinding stone is generally used.

However, the above-mentioned type causes the inherent angle of the tool to change at the time of grinding the tool, so that the tool can not be used to suit the purpose, resulting in deteriorating the precision of the tool. As a result, the partial abrasion of the abrasive stone is severe, and the working area is short, resulting in an increase in the polishing time and a shortening of the life of the abrasive stone.

In particular, tools for cutting knives are expensive, and if the knife is heat treated with special steel, it is difficult for beginners to cut the knife.

The above-described technical structure is a background technology for assisting an understanding of the present invention, and does not mean a conventional technology widely known in the technical field to which the present invention belongs.
