Blade Materials
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 european 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.
The carbon belt knives are made from a C70-type european carbon steel for the carbon-lovers out there. As any quality steel goes, stainless or carbon, all knives should be kept cleaned and oiled to prevent rusting, especially the carbon steel knives. When carbon knives leave the Grohmann factory, the blades are oiled with non-toxic mineral oil and wrapped in wax paper to preserve the blades. Keep in mind, carbon blades will corrode if not kept cleaned and oiled, this is the nature of the beast. Knives returned due to neglect will not be covered under warranty, but can usually be serviced and restored for a minimal fee (for more information, click on the Warranty section or Lifetime Limited Warranty sheet that arrived with your first quality knife purchase).
Other european steels somewhat comparable to AUS6 are used in the pocket and lock knives. Rockwell hardness 56-58 degrees is maintained throughout all of the Outdoor knives. The high carbon stainless steels used in the Kitchen Knives as well range throughout the different lines, providing a Good [poly & regular lines], Better [full tang rosewood and full tang xtra lines], and Best program [forged rosewood and forged xtra lines]. Rockwell 54-56 hardness is maintained across the Kitchen Knife lines.
