Hoping for better success with this model, fingers crossed. Decided to stay with this brand because the overall quality of the knife (materials, build, etc.) are wonderful ### ⭐⭐⭐ Weird handles in my opinion *by H***A on April 15, 2025* The wood stick out a lot more than wanted, I’ve owned different butterfly knife’s and this one is fun to fidget with good quality until the handles, I’d rather it would’ve been like the image where it was smooth and not blocky with the wood but over all decent, if anyone was looking for a fun butterfly knife I’d suggest not this one ### ⭐ Not made to last long *by P***. on June 5, 2025* My son loved this butterfly knife but the product broke in less than a month and the return replacement window already passed. So it's apparently not made well. Don't waste your money. ## Frequently Bought Together - Butterfly Knife - Balisong Trainer - Wood Practice Butterfly Trainer with Sure Spring Latch - Balisong Knives NOT Real NOT Sharp Blade - Full Stainless Steel Fake Dull Trick CSGO Fidget Toy K12W - VORNNEX Practice Butterfly knife Trainer with Sure Spring Latch, Full Stainless Steel Black Dull Balisong, Unsharpened Butterfly knives Comb for CSGO Training(Silver) - Butterfly Knife - Balisong Trainer - Black Practice Butterfly Trainer with Sure Spring Latch - Balisong Knives NOT Real NOT Sharp Blade - Full Stainless Steel Fake Dull Trick CSGO Fidget Toy K10B --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/687581788-butterfly-knife-balisong-trainer-wood-practice-butterfly-trainer-with-sure](https://www.desertcart.jp/products/687581788-butterfly-knife-balisong-trainer-wood-practice-butterfly-trainer-with-sure) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-26*
