Overview
The COSCO 91508 is a utility knife priced at $7.50 with a 4.4-star rating from 2,643 reviews. It sells 200 units per month, clearing the site's demand floor while sitting below the volume of the metal-bodied knives in this group.
The 91508 is listed with a plastic body and plastic handle, measures 6.3 inches long, and weighs 2.08 ounces.

The 6.3-inch length offers a comfortable middle ground between compact and full-size.
At $7.50, the 91508 is one of the cheaper knives here, and its 4.4-star average from a large review base shows it satisfies most buyers for everyday tasks.
