A market with only a few offers can have its price set by a single listing. Each row shows how far it sits above the cheapest price, and “price only” means the market shows a price without a link. The wear tiles and the table by wear also count Steam listings, so their offer counts run higher.

★ Butterfly Knife | Ultraviolet: collection and crates

This is a custom-designed balisong, commonly known as a butterfly knife. The defining characteristic of this weapon is the fan-like opening of a freely pivoting blade, allowing rapid deployment or concealment. As a result, butterfly knives are outlawed in many countries. It has individual parts spray-painted solid colors in a black and purple color scheme. Elegant design paired with brutal intent
