The TONAR group of companies has carried out a major technological modernization of the production of knives for ice drills:

• high-tech Italian grinding equipment of the MVM "La 500" brand was purchased;
• an additional operation of finishing grinding (“finishing”) the blades of all knives has been introduced: now the knife blade is perfectly sharp and holds an edge much longer;
• the blade of the knives is treated with a special protective compound, which was developed for the defense industry.

It is very easy to identify such knives: on their cutting edge there is a blue stripe with the TONAR.SU logo, which is clearly visible through the new blister pack of knives.
