All Comfort in the Back.The M21 G10 series offers up unsurpassed cutting power featuring deep-bellied spear point blades in the front, and lightweight, insulating, tough G10 handles in the back. In the middle is you, happy, and ready to take on tasks. Retired Sgt. Major and legendary custom knifemaker Kit Carson of Vine Grove, KY designed the M21 series. His knives have been a long-time staple of military forces worldwide and Kit wanted to create a premium knife that was everything you could ask for in a high quality work blade, but at a great price. He succeeded with a heavy-duty knife series that’s tough enough for whatever life throws your way. Made of high carbon stainless steel blades this deep-bellied spear point-style is swedged and recurved. It’s like having a bulldozer with laser-like cutting precision. A non-reflective black titanium nitride finish offers maximum corrosion resistance. So they can still look good even after the messiest of jobs. We’re sure you’ve done a few of those.The M21 G10’s feature the innovative and super strong automated liner safety. Automated liner safety is the locking liner safety innovation taken to the next level. The automated liner safety sets a pin between the locking liner and the frame. This pin acts as an additional layer of safety, so the locking liner is less likely to disengage during use. To close the knife, pull the red buttoned safety lever back, slide the locking liner over, and fold the blade into the closed position. Want one of the most secure safety systems on the market? The choice is automatic.The handle of the M21-04G is built as tough as the blade but that doesn’t mean we sacrificed comfort with it. An InterFrame build with stainless steel liners makes this baby virtually indestructible. Meanwhile the G10 scales give you lightweight, unparalleled, all weather grip. The handles also keep your hands cool in the summer and warm in the winter. It’s the best of all worlds in whatever corner of the planet you use it.So grab hold of the M21 G10. When it comes to your list of favorite features, it checks them off, with authority.Specifications:Blade Length: 3.875" (98.43 mm)Edge: PlainSteel: 8Cr14MoVBlade Finish: Titanium NitrideBlade Thickness: 0.135" (3.43 mm)Grind: HollowClosed Length: 5.375" (136.53 mm)Open Length: 9.250" (234.95 mm)Weight: 5.9 oz (167.26g)Handle: G10Style: Folding Knife with Locking Liner.

Review: A wow factor of an EDC Knife - Yeah, I know you think I'm crazy for calling it a EDC Knife if you've ever actually seen it, but I ordered it knowing it would be big with the intention to use it as EDC anyways. I am a somewhat big person at 6', but its due mostly to my hands. They're huge in comparison to most at a size 10 pinky ring and 16 for middle and ring fingers. As you can see, a large knife is for me! =] Well, I ordered this knife and it got to my doorstep in two days here in the Greater L.A. area and boy was I surprised. This truly is a big mans knife. Most would use it for a pack knife while camping, but not me. I've had this knife for almost a whole year now and it is a super knife. Out of the box, I WAS able to shave my arm hairs with it, but that didn't last long! I used it the next day in my stage production class and found myself cutting rope, carving luan plywood, and even digging with this beast. At $36 bucks, I wasn't afraid to kill this knife within a week, given, it did the job, but alas, it is still kicking a whole 10 months of that hell later! A little sharpening here and there and it will never disappoint. The blade is a mid-high carbon content stainless steal, so if (or in my case, when) the initial coating of protective stuff goes, it will get a little discolored in high humidity and even rust under prolonged exposure. (nothing a rice stone cannot handle.) I am only writing this now because every time I check the price it has been well over the $[..]I paid for it, and now its not! I need to get a spare because all my work mates want to steal it!. It is quite the conversation piece as it lacks the subtlety of a cheap 3'' knife while packing a lot more class. Anyone who has had any authority over me has challenged its street legality, but here's a lil proquo. In CA, there is NO length limit as long as it is not a gravity, switchblade or balisong knife. LA city has a loosely enforced length limit of 3'', but anyone with a reason to carry it need not worry. its basically a anti-hoodlum knife law. workers and professionals heed none of that flac. what the highest rated comment said about this knife needing some modding may be true for most, and, although i loooooove the auto-lawks, WILL need a little sanding on the release liner. The serrations on the liner didn't make me bleed, but through constant use for the first week, I did get a light callous on my right thumb. The whole knife is still as solid and almost as stiff as the day I bought it too. No wobbles at all. I abuse the living hell out of this knife, battoning wood included, and I've never had to tighten a single screw except the clip screws every once in a while. This knife is as good as any fixed blade I've used, including ka-bar bk series knives! I keep this within reach at all times from protection to safety to whittling and then some. In my eyes, a knife of this caliber is a tool and, although it would make a terrifying weapon, should be considered nothing more than a tool in responsible hands. I carried this knife for the last 5 months of my high school career before I graduated without any heat. This very knife may very well have saved my life too. One night on the freeway, I was in a 60-0mph rear-ender style crash and I was able to leave the car after the seat belt broke and locked up to tight for the release to work beause this knife was in my pocket when I needed it. I just ran the blade under the belt and poped it off. My car was rear ended not moments later just as I exited the car. Did I mention I love this knife?!? Thank you CRKT! P.S. for the holidays: Any blue collar worker would use this knife like a wonder omni-tool in a heart beat, so if you know anyone that you love and cherish, give the gift that keeps on cutting and prying and slashing and chopping. They will never stop thanking you. Though I might suggest the smaller 3'' version to those with smaller hands. Best of luck to all and happy holidays! edit as of Friday August 19th 2011: I am back again to buy yet another one of these knives, as i finally lost the last one i had. (i actually cried, as it was the one that very nearly saved my life and had become part of me.) times are hard right now as i am between jobs, but this knife is so affordable, that i bought me a new one anyways. thank you again CRKT for having such great service and products. Update 5-18-2016: So I am ordering this knife again, but luckily, it's because I am gifting it. My brother had purchased the M21-14G and though almost identical, he found that those veff serrations weren't to his liking. So now, I'm going to buy him one of these for his upcoming birthday. SHHHH DONT TELL HIM! In other news, my knife is still doing great. It looks like garbage because it has been an EDC knife for five years, and you cannot even read the model or maker info on the side of the blade due to wear, but it still has a good temper and I can still home it to a fine edge. I'd say the ~$36 I paid years ago has more than been made up for. I love this knife, and even after I retire it, I'll keep it sharp and well oiled for old times sake. And when I do retire it, I'll just be getting another one of these. Review: Fantastic Knife - I've owed this knife for just under 2 years and carried it daily. As the other reviewers have said this version is large. So for those of you out there who would love to carry a sheath knife but don't want the bulk or strange looks this is the folder for you. First off the design and construction are great. I've owned coldsteel, buck, gerber, spyerco, and benchmade folders. They were all fantastic knives and you can't go wrong purchasing any one of them. The reasons I love this particular knife are the spearpoint blade design, auto-lock, the relatively mild stainless steel, and the price. The blade design is very tough and utilitarian. It's good for carving, slicing, and mild prying. It has a very strong tip for punching through tough material. I really like the additional safety of the auto-lock. Others have complained that it's hard to close with one hand but I haven't had any problems learning how to do this. The steel is mild compared to AUS-8. For me it's a good compromise. You can keep a very sharp edge on this knife without it being overly brittle. Ofcourse this means you have to sharpen it more often but it's also faster to sharpen. The steel is maintenance free and you don't have to worry about rust. Now we come to price. For the cost, you can buy 3 of these for one good benchmade or coldsteel. Having lost both a coldsteel and a benchmade, I can tell you that I actually got sick to my stomach. I don't have to worry as much with the M21. It's every bit as good as it's competitors at a third of the cost here on desertcart. As for production quality issues, I've not seen any. I own three variants of this knife and I just ordered another smaller version of this one to have as a spare. ## Features - Safe And Secure: Automated liner safety provides extra layer of lock security - Fast Opening: The flipper deploys the blade fast - Exceptional Grip: G10 handle provides grip in all conditions - Designed by Kit Carson in Vine Grove, Kentucky - Limited Lifetime Warranty covers any defects in materials or workmanship, see company site for details ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001B70WO0 | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #80,409 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #323 in Pocket Knives & Folding Knives | | Blade Edge | Plain | | Blade Length | 3.98 inches | | Blade Material | Stainless Steel | | Blade Shape | Spear Point | | Blade Type | Spear Point | | Brand | CRKT | | Brand Name | CRKT | | Color | Black/Silver | | Customer Reviews | 4.7 out of 5 stars 998 Reviews | | Global Trade Identification Number | 00794023001853 | | Hand Orientation | Ambidextrous | | Handle Material | Fiberglass | | Included Components | Knife | | Item Length | 9.25 inches | | Item Shape | Spear Point | | Item Type Name | CRKT Large Carson G10 Handle M21-04G | | Item Weight | 5.9 ounces | | Manufacturer | CRKT | | Model Name | M21™-04G | | Model Number | M21-04G | | Number of Items | 1 | | Part Number | M21-04G | | Power Source | Manual | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Utility | | Reusability | Reusable | | Size | 4" | | Special Feature | Reversible Pocket Clip, Fast Opening | | Special Features | Reversible Pocket Clip, Fast Opening | | Style | Black Blade / G10 Handle | | UPC | 794023001853 745369214988 | | Unit Count | 1 Count | | Warranty Description | Limited Lifetime Warranty | ## Product Details - **Age Range (Description):** Adult - **Blade Material:** Stainless Steel - **Brand:** CRKT - **Color:** Black/Silver - **Handle Material:** Fiberglass - **Included Components:** Knife - **Model Name:** M21™-04G - **Recommended Uses For Product:** Utility - **Special Feature:** Reversible Pocket Clip, Fast Opening - **Style:** Black Blade / G10 Handle ## Images ![M21-04G Outdoor Folding Knife with Liner Lock, Black, M21-04G - Image 1](https://m.media-amazon.com/images/I/61AIOl60yIL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A wow factor of an EDC Knife *by R***R on December 4, 2010* Yeah, I know you think I'm crazy for calling it a EDC Knife if you've ever actually seen it, but I ordered it knowing it would be big with the intention to use it as EDC anyways.

Having used them daily, some for years; and believing that they are as much a matter of being dressed as wearing pants . I can say Crkt makes great production knives. They are made on cnc machinery and the fit and finish are uniformly good from one knife to the next. I have several of the carson (lic) M16 M21 and M4's I love the design. The M16 in the shorter spear point is lighter at the point, and as such opens with less authority. the M21 has more weight out on the end of the blade so this isn't a problem. These knives are strong and can handle about any abuse you can dish out. I will not carry any other liner lock, I have had too many fail. Now as for the blade; You simply can not buy a knife that will hold an edge under heavy use for under $150 I suppose this is because so many people use their knives for prybars screwdrivers etc The steel in these knives is fairly soft , you can hone it very sharp but expect to resharpen it often. The same applies to buck gerber case cold steel sog and so on. All of these companies use the same steel, and temper it the same way then draw it so it is soft enough you won't snap the blade prying with it. This model comes without the annoying serrations, so sharpening is quick .The edge is also ground symmetrically unlike the serrated models that are ground on one side like you would sharpen a chisel. I am not sure what all the chatter is about this being such a large knife, its just a 3& 3/4" blade no larger than any other lockblade folder with a similar blade length, and narrower in cross section than most. The Lock on the liner lock is simple enough to operate and shouldn't take any reasonably intelligent over a few trys to master. The short version,. its a well made knife, much better than most in todays market Maybe a little large for a letter opener but not for a utility or skinner ## Frequently Bought Together - CRKT M21-04G EDC Folding Pocket Knife: Everyday Carry, Black Blade, Automated Liner Safety, G10 Handle, Reversible Pocket Clip - CRKT M16-01KS EDC Folding Pocket Knife: Everyday Carry, Black Blade, Frame Lock, Stainless Steel Handle, Reversible Pocket Clip - CRKT M16-03KS Folding Pocket Knife: Sandvik Steel Blade with Stainless Steel Handle, Carson Flipper Opening, and Frame Lock --- ## 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.sk/products/2429962-m21-04g-outdoor-folding-knife-with-liner-lock-black-m21](https://www.desertcart.sk/products/2429962-m21-04g-outdoor-folding-knife-with-liner-lock-black-m21) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-22*
