My original designs are typically made with A2 tool steel as the steel of choice (D2 or 154CM also available) and will have either man-made or stabilized wood handles and include a leather sheath in most cases.  This steel can stain if the knife is not maintained but it's edge holding and toughness overshadow not being stainless.  I make everything from a Bird 'n Trout knife to a larger Camp knife and everything in between.  All of my patterns are hollow ground and have a sculpted "soda bottle" type handle for comfort/ergonomics.
