Trending Knife Sharpener Products — Growth Leaders & New Top 10 Entrants
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, one ASIN forced its way in: B0GM8TBQTN booked 5K units at $29.99. On the growth side, B09PZDXSLL leads positive momentum with ▲ 200.0% MoM growth on 3K units, with B08P1LR7MW close behind at ▲ 200.0% MoM on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
