Multi-tool brands on Amazon lost 18-24% impression share between February 28 and March 22, 2026. The drop is not a seasonality artifact. It’s Cosmo rerouting.
Cosmo is Amazon’s intent-aware retrieval system, and it has been quietly reshaping query results in hardware since late 2025. We track 14 multi-tool brands across the Leatherman / Gerber / Victorinox / private-label tier. Twelve of fourteen lost meaningful share in March. The two that held both happened to have done one specific thing differently in their listing copy, which we’ll get to.
What Cosmo is actually doing to multi-tool queries
The classic search query “multi tool” used to return a fairly stable result set ranked on a blend of relevance, conversion velocity, and review density. Cosmo intercepts that query and asks an inferred question: what is the buyer trying to do? It then expands the query into intent clusters, “multi tool for camping,” “multi tool for everyday carry,” “multi tool for fishing,” “multi tool for plumbers”, and re-ranks based on which ASINs best answer those latent intents.
The brands that win in this re-ranking are the ones whose listing copy, A+ content, and review corpus contain explicit use-case language. The brands that lose are the ones whose listings read like spec sheets, “15 functions, stainless steel, 420HC blade”, without anchoring to any specific user or use case.
This pattern matches the broader query-shift trend we documented in the Q2 2026 hardware category preview: Amazon’s retrieval is moving from keyword-match to intent-match, and hardware listings written in 2018-2022 are getting punished hardest because that era was peak spec-sheet copywriting.
The data in numbers
For the 14 multi-tool brands we track:
Median impression-share decline on top 20 root keywords: -21%. Median click-through rate change: -3 percentage points. Median conversion rate change: roughly flat (so this is purely a top-of-funnel issue, not a listing-page issue). Median TACoS change: +260 basis points (brands are paying more in SP to backfill organic losses).
The two brands that held: both had listing copy explicitly built around use-case clusters. One opened bullet 1 with “Built for everyday carry” and the others followed with task-specific language. The other had A+ modules titled by use case (“For the Job Site,” “For the Truck,” “For the Tackle Box”). Neither of these are remarkable copywriting moves, they’re just intent-anchored copy in a category dominated by feature-anchored copy.
What to do about it in the next 30 days
Three actions, in order. First, rewrite bullet 1 of every multi-tool listing to lead with a use case, not a feature. “Built for [job site / EDC / camping / tackle box]” beats “15-in-1 stainless tool with locking blade” every single day under Cosmo. Second, add use-case modifiers to your back-end search terms, not just synonyms for “multi tool” but the specific tasks buyers are trying to solve. Third, audit your A+ module headlines. If they read like product attributes (“Premium Materials,” “Compact Design”), they are invisible to Cosmo’s intent layer. Replace with use-case headlines.
This is a fast, cheap fix. We’ve seen impression-share recovery start within 14 days of listing updates. The brands that delay this past Q2 will compound the loss because Cosmo’s intent-clustering improves with engagement data, and the brands ranking now will accumulate the engagement signals that lock in their position.
Multi-tool is the canary. Knife sets, work gloves, and tactical gear are next, same query structure, same Cosmo behavior. If you operate in any of those subcategories and want a Cosmo exposure read on your portfolio, Get a free audit.
