The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Context, not marks against it, and our read of the data, not a lab test.
Overview
The KeyUnity KK05 is priced at $9.49 and carries a 4.4 rating across 1,900 reviews, with about 1,000 bought in the last month. Its niche is ultralight keychain carry.
The specs list a stainless steel blade, a titanium handle, a 2.8 inch overall length and a listed weight of about 0.01 pounds, with a size marked simply as small. The titanium handle is the standout feature at this price.
This is a tool-literate buyer's micro-knife: titanium scales and near-zero weight in exchange for a very small blade. Treat it as a backup or quick-task cutter, not a primary EDC.
