Which knives drop from which cases?
A source-first way to connect weapon cases with their rare special-item pools.
Find the cheapest listing, price gap and market opportunity across CSFloat, Skinport, Steam and other supported sources.
Only validated provider evidence is priced. Missing or stale market data stays labeled instead of being estimated.
Compare exact skin variants across current marketplace asks. When an active ask is temporarily unavailable, validated completed-sale evidence can still provide a clearly labeled cash reference.
PRICE EVIDENCE Active asks are shown only from validated cached provider responses. Historical sale medians and third-party Steam references are kept separate from active listing comparisons.
Methodology →Start with Market Scanner, then inspect exact variants, fees and supporting evidence.
Filter the normalized catalog and inspect provider availability without fabricated quotes.
