The bolster of a knife is the metal part that reinforces and protects the handle in case of impact, and is also the point of balance of the knife. However, it can also be placed only at the head or at the tip. In addition, there are knives where the bolster is not present, which is called a full handle knife. The bolster also brings an additional aesthetic aspect to the knife. There are two types of steel at Arbalète Genès David. Brass and stainless steel.
