Pocket knives vary widely in price, but most well-reviewed folding pocket knives average $30 to $60, according to Knife Depot. Knife Center sells folding pocket knives for as low as $5 and as high as $4500.
The price of a knife is affected by the kind of metal used to make the knife, as well as the handle material and design. Knives made out of tool steel, high carbon steel, and rare or highly specific alloys are significantly more expensive than knives made with stainless steel and other common alloys.
The laws concerning pocket knives vary by state, and they detail the permissible lengths, blade styles, folding mechanisms and carry methods.
