Sharpening is carried out using tools such as a bar, a sharpener, a whetstone and a file.

In order for the work to be done efficiently and not require significant physical effort, it is important to control the condition of all tools. First of all, you need to monitor their sharpening, which is carried out using tools such as a bar, a sharpener, a whetstone and a file.

Sharpener tool

This tool is designed to sharpen the blade of cutting tools. Sharpeners are available in various shapes and grain sizes. The use of coarse-grained sharpeners results in scratches and nicks on the tools being sharpened. Fine-grained sharpeners remove them, making the blade smooth and sharp. When sharpening a chisel, chisel, or plane with a round grindstone, it is directed towards the blade. When working, it is important to monitor the position of the tip. It should rest completely on the grindstone. When sharpening, in order to avoid annealing the steel of the tool, the stone should be regularly moistened with water. After the point has been sharpened, it needs to be rounded a little so that when working with the tool, it is possible to avoid the appearance of chipping on the machined surfaces.

Sharpening of axes is carried out on a round sharpener. The chamfer of the tool is pressed against the sharpener and, when sharpening, make sure that the angle of sharpening does not change. In this case, the middle of the ax is held with one hand, and the butt of the tool with the other. The sharpener should be directed towards the ax. From time to time the ax and sharpener must be cooled with water. The ax is sharpened on both sides. The blade is adjusted in a circular motion on a fine-grained block or donkey.

Bar tool

A block made of sandstone is used for rough sharpening of tool blades. It removes metal quickly enough because of the large grains. Before sharpening, the bar, like the sharpener, is moistened and then fixed. Then the chamfer of the tool is pressed against the bar and, applying pressure, they drive it back and forth. After sharpening with a bar, the blade is brought on a donkey.

Touchstone tool

The touchstone is intended for grinding the blade after sharpening. In addition, it is used to remove burrs from tool blades. A blade is driven along a wheel oiled or wetted with water, making circular movements and turning the blade alternately with one side or the other until it becomes absolutely smooth and acquires a shiny mirror surface.

File tool

There are several types of files used for sharpening various tools. For example, a triangular file is intended for sharpening a saw. The size of the file in this case is determined by the size of the saw teeth. Before sharpening, the saw teeth are set apart so that they have the same height and set width. This is carried out either with adjustable pliers, or with a special tool (wiring).

Before sharpening, the saw is clamped in a vise so that the teeth protrude about 20 mm above the vise jaws. Sharpen the saw from the right side of the blade towards the left. At the same time, burrs that increase the cutting ability of the tool appear on its teeth. When sharpening, make sure that all the teeth have the same number of file movements. Before sawing raw wood, the saw teeth are sharpened on both sides. Correctly and carefully sharpened drills contribute to obtaining accurate and quality holes. As a rule, the drill is sharpened by a specialist with the necessary knowledge and experience. For this purpose, he uses files or needle files, and performs the final finishing on a donkey.

Dedicated metal drills sharpen on corundum or emery stones and round sharpening discs. In the event that the drill is a little dull, it must be sharpened with a finely notched knife file. This is done with light counterclockwise movements.

Sharpening of the scissors blades is carried out at an angle of 70-74 °. In order to significantly reduce the friction of the knives on the blades, an equal 2-3 ° clearance angle is made. To prolong the life of all cutting tools, keep them protected from dust and moisture. Now you know how to properly sharpen tools - an ax, a saw, a knife, cutting tool blades.
