Frosty Lake is an uncommon tier crate weapon that could have been opened from Winter crates. Its design consists of a decorated snowman next to a northern - style cabin on a frozen lake, surrounded by snow - encrusted hills, along with a white hilt tainted with light blue and a light blue wrapped handle. Its effect consists of puffy white snow clouds appearing randomly over the knife. It has normal range and sound effects if equipped when playing as the killer. Players had a good chance to get these due to their tier.
