Handle Materials

Kershaw handles are fashioned from a number of different materials for durability, grip, weight, and style.


Aluminum is a lightweight, yet strong and durable material. Anodizing makes aluminum even stronger and enables Kershaw to add scratch and fade resistant color to knife handles. Some handles are bead-blasted for a matte texture.

Denser and heavier than iron, this natural metal starts out reddish-orange in color, but over time will gain a patina, like a copper penny. The patina is a result of oxidation, and the colors it turns will change with time as well. Copper makes an interesting knife handle material due to the changing patina. Depending on how you handle and use it,the knife will look different throughout its life.
