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

Overview
The SATC diamond sharpening stone is priced at $17.59 with a 4.6-star rating from 2,186 reviews, and about 600 sold last month. The title lists a 2-sided 400/1000 grit, so it is a double-sided diamond stone covering coarse and medium grades.
The listing adds a 1.9-pound weight, sold as a single piece, but no dimensions or model number. Diamond plates like this resharpen quickly and stay flat, and the 400/1000 pairing handles repair and general edge-setting, though it stops short of a fine polish.
At $17.59 with a documented grit spec and a diamond surface, it is one of the better-value sharpening picks in this group. ToolHandle is an Amazon Associate and earns from qualifying purchases, which does not influence our rankings.

Performance notes
A diamond plate cuts fast and stays flat, and the 400-grit side handles repair while the 1000-grit side sets a working edge. It does not reach a fine polishing grit, so pair it with a higher-grit stone if you want a mirror finish.
What buyers say
Owners rate it 4.6 stars across 2,186 reviews, with around 600 sold per month. That mix of a low price, solid rating, and steady sales points to a popular budget diamond stone.
