Materials, Grinds & Lines
Grohmann takes pride in their products and that means using high quality materials. Grohmann's most popular stainless steel in the outdoor fixed blade knives are fashioned from German high carbon stainless, such as 4110, which is somewhat comparable to the USA 440 series. We maintain a 56-58 degree rockwell hardness on all outdoor knives. This steel has withstood the test of time due to its ease of resharpening and long lasting edge holding ability.
The other choice for the fixed outdoor blades is a German carbon steel which is 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, but especially in the carbon steel knives. They tend to hold an edge longer and sharpen up faster than the stainless, but they will corrode if not kept cleaned and oiled at all times. 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. Carbon will corrode if not kept cleaned and oiled, this is the nature of the beast, so be sure to wash your knives after use, dry and apply a light oil. Knives returned due to neglect will not be covered under warranty, but can usually be refinished 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).
Pocket & Lockblades: 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.
