Ahti-puukko´s blade is made of black and hardened carbon steel, or alternatively stainless steel.

Because of the high-quality blade materials, the knives stay sharp and are also easy to sharpen. Dry and clean the knife after use. For example cooking oil will protect the carbon steel blade from rust. Sharpen the knife regularly, a totally dull blade is always more difficult to sharpen. A wooden shaft is not dishwasher-safe. Ahti-puukko is proudly made in the traditional knife-manufacturing town of Kauhava in Ostrobothnia, Finland.
