Kitchen Knife Sharpener Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Astercook is the best-performing kitchen knife sharpener brand in July 2026, moving 10,000 units across 1 ASIN for 18.9% of Top 10 volume. KITCHELLENCE follows with 7,000 units (13.2%), ahead of longzon on 7,000 units (13.2%).

Volume is spread across 10 brands, with the top three holding 45.3% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $13.49 to $39.88, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0GM8TBQTN booked 5K units at $32.99. On the growth side, B0C38N7KMQ leads positive momentum with ▲ 500.0% MoM growth on 300 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
