1,314 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other hand tools and workshop hand tools we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Knife GB-04 is a 3-piece sharpening stone set priced at $19.99. It holds a 4.5-star average across 1,314 ratings, which is a solid track record at this price, and the listing reports about 100 buyers in the last month.
The data is thin on specifics: the kit weighs 16 ounces and ships as 3 pieces, but no grit numbers, stone material, or base details are listed. Treat it as an entry-level kit rather than a precision setup.
For casual knife and tool touch-ups, the price and rating make it an easy low-risk pick. Buyers wanting documented grits or a large bench stone should look elsewhere.

Performance notes
With three stones in the kit and a 16-ounce total weight, this is a compact set aimed at general edge maintenance rather than heavy steel removal. Because grit ratings are not published, plan to confirm the coarseness of each stone after purchase.
What buyers say
A 4.5-star average across 1,314 ratings points to broad satisfaction, and roughly 100 monthly buyers suggest steady, if modest, demand.
