Sleipner steel is a well-known improvement upon D2 that is used in commercial meat slicing environments. It's wear and corrosion resistance makes it a reliable, day-to-day workhorse for cutting without losing its edge. Just like D2, it performs well in many environments and is a great entry-level blade steel for the first time knife user. It can be touched up in the field and trusted to stay sturdy across tough environments experienced while hunting, camping and more.
In short, it is tough and resistant to wear and chipping, and it's affordable. We use D2 and Sleipner on many of our knife models to provide a quality EDC at an affordable price. When you buy Sleipner, you are not sacrificing quality and durability.
