The biophase is razor sharp (learned that the hard way already 😂) and is very well balanced with a centre of gravity right in the middle. Also is the lightest knife I have ever held. I cannot begin to describe it. I really love the button lock mechanism it’s something new that I haven’t seen before and I find it really neat. What more can I say? It’s a beautiful EDC that can be used in a variety of different jobs. The clip is very sturdy as well (a problem I have had with past knives). Not to mention it’s just sexy as hell. Little bit pricey but great value for what you get. ### ⭐⭐⭐⭐⭐ A quality knife, so light you'll forget it's in your pocket... *by on Reviewed in the United States July 3, 2026* I bought this for myself after buying one for a friend for Father's Day. I love it. It's a very substantial knife in Nitro-V blade steel, but weighs next to nothing. It's Civivi so you get that We Knife quality for a price thats more affordable on a budget. And it's sharp! With plenty of opening options, button lock, flipper tab, etc. And the hollow grind looks and feels amazing! ### ⭐⭐⭐⭐⭐ Breathtaking *by on Reviewed in the United States July 8, 2026* I've purchased 7 EDC folding knives over the past couple/few months and never once did something make me have an audible noise when I opened the package - until this one. In burgandy. It is visually fantastic, super sharp and weighs less than 2.5 lbs. Very playfull. I am extrememly happy with this purchase. ## Frequently Bought Together - CIVIVI Pocket Knife for Men, Biophase Flipper Tactical Folding Knife, 3.48" Damascus Blade Aluminum with Carbon Fiber G-10 Handle, Lightweight Skeletonized EDC Knife for Camping Hunting, C23083C-DS1 - CIVIVI Incindie Pocket Knife for Men, Folding Knife with 3.48" Damascus Blade Milled G10 Handle for EDC C23053-DS1 (Ivory) - CIVIVI Elementum II Pocket Folding Knife, 2.96" Damascus Blade Utility Knife with Deep Carry Pocket Clip for EDC C18062PB-DS1 --- ## 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/650204061-biophase-pocket-knife-for-men-3-48-damascus-blade-c23083c](https://www.desertcart.jp/products/650204061-biophase-pocket-knife-for-men-3-48-damascus-blade-c23083c) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-09*
