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 BIIB BI-91-Yellow is the value-and-volume pick here. At $8.49 it is among the cheapest tools in this group, and at roughly 2,000 sold a month it has the strongest demand of the lot. Buyers back that up with a 4.5-star average across about 7,400 reviews.
The listing gives you a few real specs: an aluminum body, a 2.08-ounce weight, and a small size. That makes it a genuinely light, compact tool. What it does not list is the blade material or a breakdown of the functions, so you are buying on price, weight, and a solid rating.
For a low-cost everyday carry or backup tool, the BIIB BI-91-Yellow is an easy call. The aluminum build and featherweight feel match its grab-and-go purpose.
