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 Spyderco SYNCHKG067343 is a sharpening stone priced at $88.49 with a 4.7-star rating from 1,016 reviews. At that price it is among the most expensive options in this group, sitting just below the $99.80 SHAPTON set.
The listing gives dimensions of 10 by 2 by 10 inches and a single-piece pack, but the stated item weight of 0.01 ounces is obviously a placeholder rather than a real figure, and no grit is listed. Spyderco is best known for knives and sharpening systems, which is the main reason to pay up here.
If you trust the Spyderco name and want a sharpening tool from a knife specialist, the 4.7-star score backs it up. ToolHandle is an Amazon Associate and earns from qualifying purchases, which does not influence our rankings.

Performance notes
The listed 10 by 2 by 10 inch dimensions suggest a sizable footprint, but with the weight figure unusable and no grit stated, the spec sheet leaves key details unconfirmed. Lean on the Spyderco name and the 4.7-star rating rather than the published numbers.
