Beefier than an M16, the M21 is a formidable piece for anyone to carry.

Everyone most likely knows at least  one other person who has the ability to narrate extremely well and has ability to draw a listener completely into a story they retell. How many plant the hook and slowly reel in the listener, who is captivated by the idea, and then surprise them as the entire story was about something completely different from what was originally believed? Here at TPF, we were offered a chance to test out a bigger brother to the M16. That was when TPF was provided an M21 to review. Suffice to say that the excitement level at TPF was excellent and when the M21 finally came from Columbia River Knife and Tool we were extremely pleased. The author wonders if any of our readers was caught in the hook of the title?

The MG21-14G

Designed by Kit Carson and manufactured and distributed by CRKT, the M21 is a heavy-duty version of CRKT’s famous M16 line of knives.

Unfortunately this M21 is not the famed military variant of the classic M-14, nor a Norinco clone version of that illustrious firearm. In this installment of TPF, the M21 reviewed is an enhanced cousin to the M16, a folding knife designed by Mr. Kit Carson roughly a decade ago. Using his decades of military experience, personal knife making skills and outdoor knowledge, Mr. Carson designed the M16 to be a true functional knife. In 2003 the M16 was voted one of the top 10 tactical folder knife designs by Blade Magazine. The M16’s legacy has continued to this day as it is still in production and is still used as a benchmark versus other knives.  The M21-14G, as stated before, is an enhanced brother to the M16, measuring an impressive 135mm (5.3″) long while closed and massing a fair 167 grams (5.9 oz.). These larger blades of the M21 series have also earned the nickname of ‘Big Dog’ for it’s overall size and sporting a 3.6mm (0.14″) thick blade with a length of 98.4mm (3.87″).  The M21-14G version in this TPF installment has a self-described as a deep-bellied spear point profile, measures 235.0mm (9.25″)  when fully opened and features a trademarked series of Veff serrations.

Bigger handle, tougher blade, more carry options equate to a full redesign of the iconic M16 into the M21

For those individuals who are unfamiliar with Veff serrations, they originated on commercial knives back in 2006 and TPF has quoted from Mr. Veff’s website the following:
Veff serrations are unlike traditional serrations which are usually small scallops oriented at 90 degrees to the blade cutting edge.  Veff Serrations are wide and cut at about 50 degrees to the cutting edge.  The resulting cutting points bite instantly and dig deep upon contact while the large surgically sharp valleys slice smoothly and effortlessly.  Unlike traditional serrations that tend to snag and stick while cutting rope and similar material, Veff Serrations slice through cleanly and easily.  This produces dramatically improved cutting ability on rope, webbing, strapping, hoses, leather and vegetation.  Veff Serrations have been extensively tested and have proven to be the most efficient and effective serrations to date.
CKRT has in fact exclusive manufacturing rights to this design, other than Mr. Tom Veff customizing the serrations onto selected knives. The orientation change creates an effect similar to a series of miniature gut hook style cutting surfaces. The profile increases the cutting surface length of the serration edges, the small ridges between help create the sawing effect and draw the item being cut into the edge.

MG21-14G Veff

Showing off the Veff serrations and Kit Carson’s signature knurled thumb studs, the M21-14G is a hefty folder

The blade of the MG21 is manufactured from 8Cr14MoV stainless steel like many CRKT folding knives and is one of the higher quality knife steels available from China. The metallurgical properties place it somewhere between 440B and 440C stainless steel characteristics. With the blade hollow ground and treated with a Titanium Nitride coating, the M21-14G is a very sharp and imposing  looking tool. To open the knife, a pair of knurled thumb studs are attached to the blade’s spine for ambidextrous opening, as well as the “Carson Flipper” incorporated in the blade itself. The Carson Flipper was introduced nearly 15 years ago and is a kick incorporated into the actual blade which allows for partial opening of the blade through use of a finger on along the back of the closed knife. Now a very commonly feature on SAO knives, this version of the kick is used in conjunction with a slight wrist movement to obtain blade opening speeds similar to spring assisted knives. When the knife is in open position the ‘Casron Flipper’ tab also serves as a means of preventing the user’s hand from sliding into the cutting edges during usage.

MG21 the guts

This M21 is a very large and beefy blade which is locked into position via a liner lock, and CRKT also utilizes an AutoLAWKS system on the blade which prevents inadvertent closing of the folder. The AutoLAWKS is a spring actuated lever which interposes itself behind the liner lock once the knife is fully opened. This prevents the liner lock from slipping out and having the blade close at inopportune times. In order to close the blade , the AutoLAWKS. lever must be shifted, which allows the liner lock to be disengaged. This can be done one-handed with practice, but would require time and repetition to make such a smooth manoeuver. The 14G blade version incorporates grips manufactured from black G10 and have a textured surface finish to allow a firm grip regardless of weather conditions and the grip halves are retained by a set of Torx-head screws. While the knife itself comes with a retention clip setup for tip down carry and located on the right side of the knife, there are provisions for mounting the clip on either side and in tip-down carry positions. The clip is also secured by a trio of Torx-head screws.

Designed by Mr. Kit Carson to be a rugged, heavy-duty knife based upon the successful M16 predecessor, the M21-14G has an MSRP of $89.99 USD. Other options for this size M21 include double ‘Carson Flipper’ tabs to create a cross guard, colouration changes, and the option for a plain ‘Razor-Sharp’ cutting edge. TPF Online thanks CRKT for its support in allowing us to continue to review its product lines. The M21-14G which is available at many locations across Canada including Wholesale Sports which has numerous storefronts and an online store as well. The final decision on the knife’s classification of Tactical, Practical or Fantastical is up to you, the reader.
