Rarest Knife in Survive the Killer

There is no single rarest knife in Survive the Killer! (STK), game ID 4580204640. I keep three answers, each with its own ruler, all read on 31 Oct 2026.

Fewest copies

1. Galaxy — 100 copies. Developer and community-manager giveaways since 30 Mar 2021. Not a crate.
2. Santerror — 214 copies. Winter 2025 crate, confirmed by a community manager on the wiki.
3. Milky Way — 401 copies, from a 7-day Black Market Briefcase at 1 in 5.

Highest published price

1. Galaxy — 200,000,000 on STKTradings as of 30 Oct 2026, matching the wiki's figure. GalaxyValues had no cell I could fill.
2. Santerror — 32,500,000 on both STKTradings and GalaxyValues, with a GalaxyValues range of 32,500,000–35,000,000.
3. Milky Way — 23,500,000 on both boards. Range on GalaxyValues, dated 16 May 2026, was 22,500,000–25,000,000.

Lowest drop rate

Santerror's crate chance is 0.01 percent, one in 10,000, at 799 coins during Winter 2025. That is the sharpest rate I found written down. Galaxy has no drop rate because it was handed out. Milky Way's case was 1 in 5 during a week-long sale, which is common compared with Santerror and rare compared with a shop knife. The knife table holds the rest of the named weapons, including ones with empty price cells.

If you came from a trading argument, take the price list to the calculator and do not let a copy count pretend to be a value. Slyce Entertainment has not published an official rarity crown.
