Grohmann takes pride in their products and that means using high quality materials. Grohmann's most popular steel in the outdoor fixed blade knives are fashioned from flexible, high carbon stainless steels, such as 4110, which is somewhat comparable to the USA 440 series. This steel has stood the test of time due to its ease of sharpening and edge holding ability. Handles are as important to the quality of Gromann Outdoor knives as are their blades. Since all handles involve natural materials, no two handles are alike. Safety, comfort, balance and lasting beauty are handcrafted into each one. After all, your knife must "feel right".
