The production and sale of Finnish handmade puukko knives, now called Lauri, was organized by the jeweler Johannes Lauri in Rovaniemi (Finland) almost 90 years ago, having founded a knife factory in Pohjolankatu back in 1924. Having survived the difficult years of the Second World War, the company founded by Johannes Lauri continued to exist and, in the course of a series of transformations, was transformed into the company Lauri tuotteet Oy, which is still engaged in the production of blades, knives and related materials.

The descent on the blade is implemented with a call to the shank, without a horizontal heel and rikkaso. The steel from which the blade is made is 80CrV2. The blade is hardened to a hardness of about 58-59 HRC, which implies good tolerance to low temperatures. Steel grade 80CrV2 - carbon, non-corrosion-resistant steel of German production. 80CrV2 steel composition: C (0.75-0.85%), Si (0.15-0.35%), Mn (0.3-0.5%), Cr (0.4-0.6% ), Mo (0.1%), Ni (0.4%), V (0.15-0.25). Steel 80CrV2 is considered to be very good in terms of strength characteristics, resistant to blunting, easy to machine.
