Axes PETROGRAD
Axe is a truly great tool with a very rich history and still not fully revealed potential.
What is an ax and which one to choose?
Axe is primarily a tool for working with wood. This may be felling trees, logging, chopping firewood, cutting wooden utensils and other operations. Axe consists of the ax itself (the head) and the handle holding it, an ax handle.
Axes are divided by function, purpose, and no doubt by nationality. Over its centuries-old history, the axe has undergone many changes, and so far some companies manage to invent it in a new way.
Types of axes
We divide axes into several main categories: hiking axes, carpentry axes, wood axes, axes for wood felling, as well as universal and special axes.
Each of these types is characterized by a special, inherent form, the shape of the cutting edge, the length of the handle and other features.
An outdoor axe is often an axe with a not particularly large head with a long or medium handle. A long handle compensates for weight and gives more inertia during chopping, a small handle gives more control and takes up less space.
The shape of the cutting edge is universal, it allows both to chop confidently and planing.
Carpentry axes, in turn, are further divided into several subtypes: for cutting bowls, cleaners and for imparting planes. Differ confident weight, medium or long handle. For cutting, a radius blade with a thick thick blade is used. Cleared axes are distinguished by a straight blade and a smaller mass. For processing logs in timber, special one-sided axes are used with a special side grip and one-sided grinding.
The carving axe is characterized by small size, at the same time, this ax has a longer cutting edge relative to the ax itself. These axes have a strongly protruding toe and a deep set heel. The handle of the ax is also different and is designed for two different hold: closer to the head for precise cutting and far away for easy cutting.
Universal axes are trying to combine all the advantages of the previous ones and are a cross between them all.
Specialized axes meet some narrow purpose: chopping wood chips, making shingles, sanding and so on. Their form is the best suited for almost a single operation

The high hardness of carbide-silicon grinding materials allows you to confidently process not only carbon steels, but also hard alloys, which is impossible on stones made of electro-alumina powders. In addition to performance, it is worth noting the extraordinary tactile sensations when sharpening a tool. Stones quickly give a slurry and produce a very pleasant sound.
Water stones PETROGRAD are distinguished by high performance and geometry in a state of delivery.
In the characteristic of a water stone are specified: the first letter - hardness (I, J - soft, K - average); Japanese grain size according to JIS R6001-1987 is 150 (80 microns), 360 (34 microns), 500 (24 microns), 1000 (12 microns), 2000 (6 microns) and C is silicon carbide.
