Best Butterfly Knife Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Smith & Wesson is the best-performing butterfly knife brand in July 2026, moving 8,000 units across 2 ASINs for 32.0% of Top 10 volume. FUNBRO follows with 4,000 units (16.0%), ahead of CIVIVI on 3,000 units (12.0%).
With 9 brands splitting the Top 10 and 60.0% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $7.99 to $29.74, which frames the price band a competing listing has to justify.

Trending Butterfly Knife 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: B07DD69QN3 booked 1K units at $37.96, with ▲ 42.9% MoM change. On the growth side, B0C1ZQ58NW leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B08J7TB5BC close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
