The Iisakki Järvenpää Company was founded in 1879 and is the largest manufacturer of knives in Kauhava, Finland, a well-known town which has a long and rich history of knife making. Handles are made from locally sourced curly birch wood, occasionally with birch bark spacers. Fittings are also produced internally at their factory. The result is a complete Iisakki Järvenpää knife that is 100% sourced from the same manufacturer, designed and created to work together seamlessly. The blades are all ground individually, making each one a bit unique, and all are stamped with Iisakki Järvenpää's signature. Sheathes are stamped with images of reindeer and forests, highlighting Finland's strong culture of outdoors, hunting, and woodcraft. Järvenpää has an exceptional focus on quality, and they produce knives which are both beautiful as well as highly functional.
Knife blades are either high-carbon steel or 420 stainless steel. Most sheathes (except for the flat-style sheathes used by the Scout knives) have a plastic liner to prevent the blade from accidentally slicing through, and the belt loop is attached by a metal D-ring so that it swings freely and keeps out of the way when you're crouching or sitting.
The Iisakki Järvenpää web site can be found here. It contains stories about the manufacturing processes and company history in several languages, including English. Järvenpää knives can be found all over the world, and they can always be seen in antique stores, swap meets, gun shows, and at the bottom of grandpa's toolbox. These are knives which are crafted to last for generations.Here's a great detailed review of a model 1244 Aito. It shows the excellent craftsmanship and detailing that Järvenpää puts into all of their knives.
