The knives I make are for hard use. Coming from Alaska, knives see harsh conditions year round. That’s why I use materials that hold up to those conditions. Carbon fiber or G10 pins for the mechanical connection to the knife handles. G10, Micarta, stabilized hardwoods, or stabilized bone for the handles. Kydex for the sheath. Stainless steel or Coated High Carbon steel for the blade steel. Pattern Welded Steel in certain application as well.
