Ahti knives are manufactured in Kauhava, Finland, which has a long and rich history of being known for knife making. The Ahti knives are made by Reino Kamppila and his son, who operate a fourth-generation family business of knife making. Theirs is a smaller shop, but they produce knives of excellent quality and workmanship. The carbon steel (0.8% 80CrV2) blades are hardened to about 59 on the Rockwell scale, and knives having stainless steel (X50CrMoV15) blades are hardened to about 57 Rockwell. All blades are made by Laurin Metalli of Finland. The knives and their leather sheathes are works of beauty, and are visually appealing as well as satisfyingly functional. The blades are lightly inscribed with the Ahti logo. As with most Scandinavian knives, the handles are made from curly birch, sanded and stained, and finished with linseed oil. The fittings on the knives are polished brass, and there are plastic inserts in the sheathes to protect both the sheath and the hand, as these knives are quite sharp and could easily slice through both if inserted incorrectly into the sheath. The blades have full-length tangs, with the end of the tang secured by a nut at the pommel. The belt loops aren't attached directly to the sheathes, but rather by a small metal ring, which lets the sheath dangle and swivel to make it easier to move and sit with the knife on your belt.
