Review: My favorite design! - The blade design and carrier are what makes this little knife my favorite. I hope they make more of these in different sizes with the same hole πŸ•³ locations on the blade and carrier. I like the light weight of the blade as well as the security that the hole πŸ•³ gives me. I do not like dropping my knives and the πŸ•³ allows me to work with blade in hand while secure on my finger. The holster design also allows for the draw to be more comfortable and easy. Perfect design for most of my blade usage needs at home or at work. Nice and sharp as well. Review: High quality blade at a great price - I bought both the Double Agent and Double Agent II and have been very satisfied with both. The carbon steel blades are STRONG and ship with a very respectable edge right out of the box. If you're looking for a self defense blade that almost can't be knocked out of your hand and is highly resistant to disarming techniques, I recommend you give these a look. Very light weight, can be carried as a neck knife or in just about any other way imaginable. The sheath is a very clever design and adds very little bulk. The release system is definitely different; you have to press in a button through the forward finger hole to release the blade. It's cumbersome at first, but can be mastered quickly with modest practice. If you intend to carry it for defense, YOU MUST practice this and master it FIRST. I like the Cold Steel blades for their combination of toughness, hardness, and ability to hold an edge, I have yet to be disappointed with one of their blades.

The sheath can be hung in an almost horizontal position. The handle (being the heaviest part) will hang lower than the point. **Q: What is the blade length?** A: A little over 3 inches. It is a nice lite knife easy for concealing. **Q: How is this a "secure ex" sheath?!. I really like the knife but it pops out easily, terrible sheath!. Anyone else?** A: Yes the sheath for mine was horrible too. I ended up heating the clip with a heat gun so it stays in the finger hole. now it seems to be working fine. **Q: What kind of steel is the blade made of?** A: It is some sort of high carbon stainless. The blade is hollow ground and can be sharpened nicely. If worn around the neck, make sure you clean and oil the blade frequently because the high carbon content will corrode quite easily. A trip to the Cold Steel website will tell you what alloy the steel actually is. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My favorite design! *by E***. on December 3, 2024* The blade design and carrier are what makes this little knife my favorite.

Only problem is: they give you a necklace to hang it. But didn't give a small ring to let the knife sit flat on the chest. Perhaps manufacturer or engineering overlook. Otherwise, its great. ## Frequently Bought Together - Cold Steel Double Agent Durable Lightweight Japanese AUS8A Steel Karambit Shape 3" Fixed Blade Tactical Outdoor Hunting Knife, Kray-Ex Handle, Secure-Ex Sheath - Cold Steel C-Clip Small (Pack of 2), Black - Cold Steel Double Agent II Plain Edge Durable Lightweight Japanese AUS8A Steel Clip Point Shape 3" Fixed Blade Tactical Outdoor Hunting Knife, Griv-Ex Handle, Secure-Ex Sheath --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/41037466-double-agent-durable-lightweight-japanese-aus8a-steel-karambit-shape-3](https://www.desertcart.kr/products/41037466-double-agent-durable-lightweight-japanese-aus8a-steel-karambit-shape-3) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-30*
