## Description

Product Description Work In the Front. 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: Solid CRKT M16 Model for FrameLock Fans - So I've got many knives, I'm definitely a collector. I've got SpyderCos, Buck, Cold Steel, Gerber, a Benchmade, Kershaws, etc. The CRKT M16 comes in many varieties, and usually equipped with a liner lock. Many different types of handle, blade shape, length, etc. This version was the 3.85" tanto blade with a framelock. I like framelocks & CRKT so I bought this basically just to show support for their decision to try an M16 with a framelock. Very solid in stainless steel. The flipper action is very good, especially for a $50 knife. The lockup "feels" more secure than a liner lock simply due to my understanding of how these locks work; the width of the frame is always thicker (and sturdier) than a liner. This knife would theoretically handle more punishment due to its locking mechanism. Tanto blades aren't the best for repeated deep cuts & slices due to the lack of a belly or curve in the blade, but they're tough & the best for thrusts and stabs. This makes a good tactical option, carried for self defense purposes. The steel holds an edge well & I sharpen it with a Lanksey 2D2C rod box. The price makes this a viable option for my EDC, because if I were to break/lose it I wouldn't be as enraged as if I break a Benchmade or a ZT. Some knives cost so much they end up sitting in our homes, safe & sound. Despite the good price I have a large amount of experience & confidence in CRKT, so I place my life in their hands quite often. I carry this knife more often than my $160 SpyderCo PM2 simply because it's big, solid, strong, and priced more fairly. If you have a Rolls Royce, a Bentley, a Ferrari, and then you also have a Charger or a Camery, you may find yourself more comfortable doing your daily tasks in the less expensive options. I have better looking knives, stronger locks (Triad or Ball Bearing for an example), etc but the point is I very rarely need a $200 tool with an 800lb lock. This lock will work excellently & flawlessly for cutting cardboard or defending myself against another human. I have zero reservations recommending it for a tactical EDC option, and that's what it's designed for. It's a Framelock? A Tanto blade? Then it's meant to withstand stabbing actions with no lock failure.

### ⭐⭐⭐⭐⭐ Great EDC for large hands
*by M***C on May 16, 2019*

My comparison for this knife is against a CRKT Crawford Kasper that I carried for years and was my shaving sharp daily tool. This knife was purchased as a replacement (stolen) for that so my comparisons will be between the two. The secondary locking mechanism is very similar but in the Kasper it is manually deployed and in the M21-04G it is deployed automatically when the knife opens. This is a major improvement over the design and is a key feature that I like about it. It does take a few practice tries to be able to close it one handed but it is very doable and becomes second nature within a few days. I would much prefer that it lock open as it does if I ever had to use it defensively so I would still put this to the "good" column. The blades are both made of the same steel so I expect the same reliable sharpness from it and wearability which for my use was about 3 months between sharpenings and daily use at work while maintaining a shaving sharp edge the entire time. Both knives are large enough to fill a large hand and be comfortable which is hard for me to find. My hands are 8" from fingertip to wrist and 4 1/4" across the palm for comparison. Most pocket knife handles are so small that it feels like I can only hold them with two fingers and a thumb and that doesnt feel like a lot of control to me. I did have to do some hunting both on Amazon and CRKT's website because I wanted a knife with a smooth edge and no serrations and I could not find it in a full size. It kept linking me back to the M16-01KZ, which I am sure is a fine blade, but is too small for what I wanted. All other search results showed tanto and serrated blades. Only after a specific part number search did I find this one, the M21-04G. I would have preferred one without the black finish on the blade and just steel but that is personal preference and in no way do I regret my purchase. Pick one up, you won't believe how comfortable it is to work with.
