Most conveniently for sharpening of the cutting tool the mechanical sharpened of 100-120 mm with a round stone in diameter and it is desirable the greatest thickness. Manual sharpened considerably facilitates work, saves time spent for sharpening of the tool. Sharpening receptions here others, the cutting corner also is formed differently.
Usually mechanical sharpened has the adaptation for installation of a piece of iron under a necessary corner and its deduction in this position. If it is not present, a piece of iron keep the left hand in such position that facet and stone planes coincided, and the back end rested against a table. On verstachnoj to a board on which it is screwed sharpened, it is possible to note pencil riskoj position of a sharpened piece of iron or to emphasise, using strubtsinku.
On tochile sharpen the tool, without moistening a stone water, therefore it is necessary to watch that the edge did not heat up too strongly, before metal dimness, differently the steel can be released and repeated training is required.

Occurrence will testify To the sharpening termination on a cutting edge of agnails besides. Editing is made on usual oselke in already described way. But it is necessary to consider that the facet does not represent now an equal plane, it is bent according to diameter of a circle. During editing on oselke the top and bottom sides will grind off to mirror shine only. It reduces a friction of a facet during wood cutting. Besides, it is easy to increase a sharpening corner, having changed its inclination in the course of editing on oselke. Editing of the piece of iron ground thus can repeat some times without preliminary processing on tochile. .
Cabinetmakers before starting to work with decorative plywood or firm wood when special cleanliness of cutting is required, resort to such reception. Directed on oselke a piece of iron put an edge on a knot in a board, strike on the handle a hammer, and then again correct an edge on oselke even more accurately.
