Review: Absolutely a great EDC - I love this knife, I use it everyday for work and I cut open hundreds of boxes and day, it holds a edge perfectly, the size is great and it is very sturdy, very easy to operate and I love the camo and the clip is sturdy as well Review: Great knife, high quality, very sharp - absolutely recommend!! - Excellent quality for this price point! It isn't too heavy and weighs about what you'd expect one to weigh. The grip os very comfortable. It is very easy to open, although it can be a bit hard to close (the locking mechanism is great!). It is very sharp and maintains its sharpness for quite a while. Design did not fade or anything, even after being exposed to sun, rain, snow, and dirt. I just bought my third knife because I keep forgetting to take it out of my backpack before I fly, so TSA generally takes it - it has passed through TSA with no issue a couple of times, though. I always come back to reorder this knife because of how much I love it! Absolutely recommend! ## Features - Spring assist Folding knife offers rapid one-handed deployment, locks securely into place with liner lock - Black stainless steel blade with thumb stud for faster deployment - Black aluminum handle with cut-out design - Pocket clip for easy and safe carry; seatbelt cutter and Glass breaker for emergencies - 5-inch closed length; 3. 75-Inch blade length with 3. 5 mm thickness ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LMPQOCA | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #20,374 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #18 in Tactical Knives | | Blade Length | 3.75 inches | | Blade Material | Stainless Steel | | Blade Shape | Drop Point | | Blade Type | Drop Point | | Brand | MTECH USA | | Brand Name | MTECH USA | | Color | Black Blade | | Customer Package Type | Secure and Compliant Packaging | | Customer Reviews | 4.6 out of 5 stars 13,926 Reviews | | Global Trade Identification Number | 00805319080718 | | Hand Orientation | Ambidextrous | | Handle Material | Aluminum | | Included Components | knife | | Item Length | 8.75 inches | | Item Shape | Folding Knife | | Item Type Name | Folding Knife | | Item Weight | 0.21 kg | | Manufacturer | Master Cutlery | | Model Name | MT-A845BK | | Model Number | MT-A845BK | | Number of Items | 1 | | Orientation | Ambidextrous | | Part Number | MT-A845BK | | Power Source | Manual | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Utility | | Reusability | Reusable | | Size | 3.8" | | Special Feature | Foldable | | Special Features | Foldable | | Style | MT-A845 Series | | Theme | Outdoor | | UPC | 805319080718 | | Unit Count | 1 Count | | Warranty Description | Limited | ## Product Details - **Age Range (Description):** Adult - **Blade Material:** Stainless Steel - **Brand:** MTECH USA - **Color:** Black Blade - **Handle Material:** Aluminum - **Included Components:** knife - **Model Name:** MT-A845BK - **Recommended Uses For Product:** Utility - **Special Feature:** Foldable - **Style:** MT-A845 Series ## Images ![MTech USA MT-A845BK SPRING ASSISTED KNIFE, 5" Closed, Black Blade - Image 1](https://m.media-amazon.com/images/I/61fjjgQIpQL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Is this knife a good quality** A: No. For the money, you can do better. The blade steel is said to be 440A, and it might be, but if so the heat treat is horrible because I've never been able to sharpen MTech's blades. I'd rather cheap knives be made of 420 because at least then, I'd be able to get them sharp. (They may not stay that way, but at least they'll be sharp for a little while. Their 440A blades come dull and they stay that way, so edge retention can be said to be excellent.) If you're on a super tight budget, get a Smith & Wesson folder; however, I'd recommend your getting a good knife, and Cold Steel makes some good budget knives and some fantastic mid- and upper-range knives. And regardless of the steel, their heat treat is spot on. **Q: How do you close the knife?** A: Turn the knife over. Look into the slot where the knife blade rests when closed. At the front of this slot there is a semi-circular notch and inside that notch is a serrated (sawtooth) arm that is holding the blade open. Push that sawtooth arm towards the belt clip. You may have to push the blade farther open to get the tension off that arm. It will move to the side and you can close the blade. **Q: Is this knife legal in California?** A: Plastic straws are illegal in CA. I doubt u guys are allowed to carry sharp object's! **Q: Is the lever sturdy enough for police work so I don't have to worry about it opening in my pocket?** A: Yes, but personally I would not use it for anything of any official capacity. It does not open smoothly enough for me using the thumb switch and mine tends to stick sometimes. Now if you use the tab on the back it's better, but for police work, I'd get one that's more dependable and of better quality. Good utility or camping knife for the money though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Absolutely a great EDC *by G***Y on July 25, 2026* I love this knife, I use it everyday for work and I cut open hundreds of boxes and day, it holds a edge perfectly, the size is great and it is very sturdy, very easy to operate and I love the camo and the clip is sturdy as well ### ⭐⭐⭐⭐⭐ Great knife, high quality, very sharp - absolutely recommend!! *by T***Z on January 23, 2026* Excellent quality for this price point!

Absolutely recommend! ### ⭐⭐⭐⭐⭐ Solid, sharp, and reliable *by E***E on August 20, 2025* This knife really impressed me from the moment I opened it. The all-black blade and handle give it a sleek, tactical look that feels much more expensive than the actual price. The color is clean and uniform, and it hasn’t shown scuffs or scratches even with regular use. The spring-assisted mechanism makes this knife incredibly easy to open with just one hand. It snaps open quickly and locks securely into place, giving you confidence that it won’t fold back unexpectedly. Closing it is just as smooth, and nothing about it feels stiff or awkward. Whether you’re new to knives or an experienced carrier, the assisted opening really sets this one apart. The textured handle has an ergonomic design that sits naturally in your hand. The grip feels firm without being uncomfortable, even during longer use. I like that the handle shape provides a secure hold without digging into your palm, and it doesn’t slip when your hands are sweaty. Comfort and safety-wise, it’s well-designed. For everyday carry, this knife is great. It’s sharp right out of the box and cuts cleanly through boxes, rope, packaging, or light outdoor tasks without dulling quickly. The pocket clip makes it easy to keep on hand, and the blade shape is versatile enough for both practical daily use and light outdoor tasks. The overall build quality is surprisingly good. It doesn’t feel cheap or flimsy at all with no rattling parts, no loose screws, and the lockup is strong. The weight is not overly heavy but substantial enough to feel dependable. The black coating on the blade has held up well, showing minimal wear despite frequent use. For under $30, this knife delivers way more than expected. Between the nice color, reliable assisted opening, comfortable grip, and strong utility, it makes for an excellent everyday carry option. If you’re looking for a budget-friendly knife that doesn’t sacrifice quality or style, this one is worth grabbing. ## Frequently Bought Together - MTech USA MT-A845BK SPRING ASSISTED KNIFE, 5" Closed, Black Blade - Spring Assisted Pocket Knife with Wood Handle Glass Breaker & Pocket Clip - 3.66" Sharp Blade - Tactical Folding Knives - for Men Women Hunting Camping Military Survival Hiking Work EDC 0207 - edcfans Pocket knife for Men Women, 8" Tactical Folding Knife with USA Flag, Small EDC Knives with Belt Clip, 4 In 1 Multitool Camping Knife with Liner Lock, Serrate, Glass Breaker, Seatbelt Cutter --- ## 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.kr/products/14830776-mtech-usa-mt-a845bk-spring-assisted-knife-5-closed-black](https://www.desertcart.kr/products/14830776-mtech-usa-mt-a845bk-spring-assisted-knife-5-closed-black) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-09-16*
