Fixed Blades

Knife blades can be made from a variety of materials. Carbon steel can be very sharp and hold its edge well, and remains easy to re-sharpen, but is vulnerable to rust and stains. Stainless steel may not able to take quite as sharp an edge as carbon steel, but is highly resistant to corrosion. High carbon, stainless steel is intended to incorporate the better attributes of both. Laminate blades use multiple metals to create layers, combining the attributes of both also. Pattern-welding layers different steel types to create patterns in the steel. Titanium has a better strength-to-weight ratio, is more wear resistant, and more flexible than steel, but less hard and unable to take as sharp an edge. Ceramic blades are hard, brittle, and lightweight: they can maintain a sharp edge for years with no maintenance, but are fragile. They are immune to common corrosion.

Handle material can also vary greatly and includes many types of wood, antler, bone, horn and synthetics like acrylic and G-10. Sheaths are usually Kydex or leather.

Fixed blades, fixed knives, straight blade knife, straight knives play a significant role in some cultures through ritual and superstition. Knife symbols can be found in various cultures and were included burial rites, so the dead would not be defenseless in the next world. A common belief is that if a knife is given as a gift, the relationship of the giver and recipient is severed. An item of value, as little as a penny, is exchanged for the gift, rendering "payment" thus completing the transaction and saving the relationship.
