}}The CQC-6 (Close Quarters Combat — Six) or Viper Six is a handmade tactical folding knife with a tantō blade manufactured by knifemaker Ernest Emerson and is credited as the knife that popularized the concept of the tactical folding knife.{{Citation| surname=Covert| given= Pat| title=Strike Force! | journal=American Handgunner|date= January 2000|volume =30| issue=1|url= http://www.findarticles.com/p/articles/mi_m0BTT/is_144_24/ai_57886950 |access-date = April 20, 2009}}{{Citation| surname=Haskew| given=Mike| title=Ground Breaking Tactical Folder Makers | journal=Blade Magazine | volume=31 | issue=2 | year=2004 | pages=24–31 }}{{Citation| surname=Shackleford | given=Steve| title=30 Most Influential People in Blade History | journal=Blade Magazine | volume=30 | issue=10 | year=2003 | pages=92–99 }}{{cite book|title=Knives 2012: The World's Greatest Knife Book|chapter=Tactical Tuxedos|first=Michael|last=Burch|page=[https://archive.org/details/isbn_9781440216879/page/52 52]|editor=Joe Kertzman|edition=32|quote=Others credit Ernie Emerson's CQC-6 (also called the “Viper 6”) conceived in the late '80s as being the model to help popularize the tactical folder.|location=Iola, Wisconsin|publisher=Krause Publications|year=2011|isbn=978-1-4402-1687-9|url=https://archive.org/details/isbn_9781440216879/page/52}}

History

In the mid-1980s, individual Navy SEALs from a West Coast team had been using personally purchased custom fixed-blade knives made by Southern California knifemaker Phill Hartsfield.

Hartsfield's knives are hard ground from differentially heat-treated A2 tool steel and are known for their distinctive chisel-ground blades.{{Citation| surname = Steele | given = David E. | title = The Hottest Grind of All | journal = Blade Magazine | volume = 24 | issue = 3 | year = 1997 | pages = 16–18 }}{{Citation |surname=Tieves |given=Bruce |title=Captain Tactical |journal=Blade Magazine |volume=25 |issue=1 |pages=41–44 |year=1998}} More accurately, they are zero ground; that is, the edge has no secondary bevel, minimizing drag when used for cutting purposes.

Emerson had long been impressed by the cutting ability of the chisel-ground edge and had asked Hartsfield's permission to incorporate it into his own folding knives, which Hartsfield granted.

When the SEALs asked Hartsfield to make them a folding knife, he informed them that he did not make folding knives and referred them to Emerson who manufactured folding knives utilizing the Walker linerlock.Dockery (2004).

Naming

Emerson's folding chisel-ground "tantō" became the sixth model in his Viper series and, while a handful of prototypes were referred to as "Viper 6", the model was soon named the "CQC-6" (CQC refers to "close-quarters combat") and was chosen by the SEALs for use.{{cite journal|last=Lang|first=Bud|journal= Knives Illustrated|year=1996|title=Ernest Emerson Profile|volume=10|edition=Folders Special|page=28}}{{Citation | surname=Garrett| given=Robert| title=Will the Rolex be Replaced by an Emerson Folder as THE Special Ops Status Symbol?| journal=Tactical Knives Magazine| volume=2 | issue=2 | year=1996| pages=58–63 }}{{Citation| surname=Ewing| given=Dexter| title=Stand and Salute the CQC7| journal=Knives Illustrated Annual| volume=20| issue=1| year=2006| pages=172–176| url=http://www.emersonknives.com/pics/KnivesAnnual06.pdf| access-date=2011-03-23| url-status=dead| archive-url=https://web.archive.org/web/20101218175108/http://emersonknives.com/pics/KnivesAnnual06.pdf| archive-date=2010-12-18}}

Writer, David Steele, refers to the CQC-6 as the sixth model after five prototypes as opposed to the next in the evolution of the Viper line of knives. Emerson, himself, says the moniker "six" was used because the SEALs in question were members of SEAL Team Six.

Design

According to the SEALs' requirements, the knife had to be corrosion resistant, designed for easy cleaning in the field, durable enough to be used on a daily basis as a tool, and capable as a weapon should the need arise.

The CQC-6 has a {{convert|3.3125|in|abbr=on}} long blade. The handle is {{convert|4.625|in|abbr=on}} long making the knife close to {{convert|8|in|abbr=on}} in length when opened. The butt-end of the knife tapers to a point and features a hole for tying a lanyard.

= Blade =

The blade profile of most CQC-6's is a Japanese chisel ground tantō with a single bevel or zero-ground blade sharpened on only one side{{Citation |surname=Dick |given=Steven |title=The Working Folding Knife |page=280 |year=1997 |publisher=Stoeger Publishing Company |isbn=978-0-88317-210-0}} of ATS-34 or 154CM stainless steel.

The blade finish has almost uniformly been Emerson's trademark satin flats and matte edges. However, some models were made with a Black Tenifer coating. The steel was originally ATS-34 but was replaced by its American equivalent: 154 CM.

= Handle =

The handle material of the CQC-6 is composed of two titanium liners utilizing a Walker linerlock and a single or double detent as the locking mechanism, although one experimental model exists with a ratchet lock.

Emerson has used exotic handle materials such as decorative hardwoods, abalone shell, and mother-of-pearl on these dress variants; these models often feature polished hardware as opposed to the bead blasted bolsters on the tactical models.

Most models feature traction grooves for a more secure grip in a wet environment and a chamfered lockface. Early knives were made with black linen micarta and later models featured a proprietary green color made exclusively for Emerson.{{cite book |last=Walker |first=Greg |title=Battle Blades: A Professional's Guide to Combat/Fighting Knives |publisher=Paladin Press |year=1993 |isbn=0-87364-732-7 |location=Boulder, CO |pages=38, 130}}

= Others =

Early models have a buffline similar to a hamon found on a Japanese Samurai Sword due to a leather buffing wheel used by Emerson to finish his blades.{{cite book |last=Dockery |first=Kevin |title=Weapons of the Navy SEALs |publisher=Berkeley Hardcover |year=2004 |isbn=0-425-19834-0 |location=California |pages=23–24}}

Unlike the typical Japanese chisel-grind, Emerson's grind is on the left-side of the blade as opposed to the right-side.{{cite book |last=Kertzman |first=Joe |title=Sporting Knives: Folders, Fixed Blades, Pocket, Military, Gent's Knives, Multi-Tools, Swords |publisher=Krause Publications |year=2007 |isbn=978-0-87349-430-4 |location=Iola, WI |page=110}}

Titanium bolsters make up the front half of the knife with the back half represented by linen micarta scales. The reasons for using titanium as a linerlock material were due to its memory characteristics and corrosion resistance.{{cite web |date=27 March 2002 |title=Titanium Alloys – Corrosion and Erosion Resistance |url=http://www.azom.com/details.asp?ArticleID=1336 |access-date=April 20, 2009 |work=The A to Z of Materials:Materials Information Service – The Selection and Use of Titanium, A Design Guide}}

The screws in the handle, and pivot are traditional straight-head screws to accommodate easy disassembly in the field with an improvised tool, if needed.

A pocket clip held in place by three screws allows the knife to be clipped to a pocket, web-gear, or MOLLE.

A few early models featured a titanium backspacer, replaced in later years by a backspacer made of G10 fiberglass.{{Citation | last = Emerson | first = Ernest | author-link=Ernest Emerson|title = Viper Knives Catalog| year = 1994|page=4}} Some early CQC-6's featured cutouts in the micarta handle slabs for a small pair of tweezers as found on the Swiss Army Knife.{{cite web|url=http://www.emersonknives.com/auction/auction_details.php?name=CQC6--Green-Canvas-Micarta-with-Tweezers&auction_id=100074|title=CQC-6 Green Canvas Micarta with Tweezers|year=2010|access-date=2011-03-23|url-status=dead|archive-url=https://web.archive.org/web/20110723072403/http://www.emersonknives.com/auction/auction_details.php?name=CQC6--Green-Canvas-Micarta-with-Tweezers&auction_id=100074|archive-date=2011-07-23}}

Variants

While each CQC-6 is made by hand by Emerson, there are certain subtle variations between models of different years.

= Early versions =

The earliest examples feature the Emerson "half-moon" logo, which is simply the name "EMERSON" arranged in an arc on the blade.{{Cite web | last = Callahan | first = Paul | title = Emerson Logo's | work = Emerson Resource Page| year = 2010 | url = http://pcknives.com/logosbody.html | access-date = 2011-03-23}}

This was replaced by the Specwar logo in 1994 which resembles the gunsight on the Stealth aircraft and the moniker "Emerson Specwar Knives".

The gunsight logo was briefly replaced by Emerson's Diamond logo for a period of 1 year(2004–2005), until the die to cut the logo was broken and Emerson resumed the Specwar log.

In 2004, Emerson incorporated his patented "Wave" opening device into the profile of the blade.{{cite journal|last=Overton|first=Mac|year=2007|title=Emerson Knives: The #1 Hard Use Knives in the World|journal=Knives Illustrated|volume=21|issue=4|pages=36–43}}

In 1994, the president of Benchmade Knives, Les DeAsis, approached Emerson to manufacture the CQC-6 on a larger scale as a factory production model.{{Citation |surname=Norman |given=Chris |title=Ernest Emerson |journal=Knives Illustrated |volume=10 |issue=4 |pages=104–108 |year=1995}} Preferring to keep the CQC-6 as a custom-only knife, Emerson instead licensed a similar design of his, the CQC-7.{{cite news |last=Fritz |first=Mark |date=2006-07-25 |title=How New, Deadly Pocketknives Became a $1 Billion Business |url=https://www.wsj.com/PA2VJBNA4R/article/SB115379426517016179-search.html |access-date=2007-01-02 |publisher=The Wall Street Journal}}{{subscription required}} Even though it did not have the craftsmanship of a handmade piece of cutlery, it satisfied customers with their own version of Emerson's work, at an affordable price and without the five-year wait.{{Citation |surname=Shackleford |given=Steve |title=The 7 Is 10 |journal=Blade Magazine |volume=32 |issue=2 |pages=42–48 |year=2005}} Benchmade manufactured automatic versions of the CQC-7 such as the BM9700.

{{Citation |surname=Pickles |given=Al |title=Innovation Sets the Pace |journal=Tactical Knives Magazine |volume=1 |issue=1 |pages=32–39 |year=1995}} Currently Pro-Tech Knives of Santa Fe Springs, California manufactures an automatic version of the CQC-7 in collaboration with Emerson.{{cite journal |last=Searson |first=Mike |date=2011-04-01 |title=The Best Knives of G2 |journal=Blade |publisher=FW Media Inc. |volume=37 |issue=5 |pages=80–84}}

The CQC-7 is similar in size and blade profile to the CQC-6 with the main difference being a rear brake at the butt of the handle of the CQC-7 as opposed to the boattail shape of the CQC-6. After the contract with Benchmade expired, Emerson began production of this model in his own factory, Emerson Knives, Inc., in 1999. The production version of the CQC-7 is not a handmade knife and features no bolsters or micarta in the handle construction. The handle material on the production model is G-10 fiberglass and the edge of the blade has a secondary bevel. There is a larger and smaller version of this knife known as the "Super CQC-7" and "Mini-CQC-7", respectively and a version with a drop-point blade as opposed to a tanto.{{Cite web |last=Hopkins |first=Cameron |year=2001 |title=Emerson Knives' CQC7 |url=http://findarticles.com/p/articles/mi_m0BQY/is_6_47/ai_74033109/ |access-date=2011-03-23 |work=Guns Magazine |publisher=FMG Publishing}} An "all titanium" handled version with a framelock was made in 2005 known as the HD-7 to commemorate the tenth anniversary of this model.{{cite press release |title=Emerson Knives HD-7 folder |publisher=Shooting Industry |url=http://findarticles.com/p/articles/mi_m3197/is_6_49/ai_n27798500/ |access-date=2011-03-23 |year=2004}}{{cite press release |title=HD-7: Emerson Knives - Spotlight |publisher=American Handgunner |url=http://findarticles.com/p/articles/mi_m0BTT/is_169_28/ai_114475622/ |access-date=2011-03-23 |year=2004}} Emerson makes handmade versions of the CQC-7 with variations similar to the CQC-6 mentioned above.

= Dress versions =

Emerson has made "dress" versions with Damascus steel blades and Titanium blades with a bonded carbide edge.

= CQC6 Flipper =

At the 2017 G9 USN Gathering knife show in Las Vegas, Emerson made the debut of the most coveted CQC6 to date, a black CQC6 Flipper.

= Japanese versions =

In Japan there are strict laws regarding the manufacture and possession of tantō blades.{{cite book | last = Darom| first = David | author-link = David Darom|author2=Eric Eggly |author3=Francesco Pachi |author4=Paolo Saviolo | title =The Great Collections (Modern Custom Knives) | publisher = Chartwell Books| date = April 30, 2008| page = 288| isbn = 978-0-7858-2360-5 }}

In response to this, Emerson made a small batch of CQC-6's with a more conventional blade-grind for a Cutlery Show in Seki City. These knives featured the grind on the right-side of the blade as opposed to the left.

= Super Six =

Emerson makes a 10% scaled-up version of the CQC-6 known as the "Super Six" and a 10% scaled-down version retro-named the "CQC-5". Like all of Emerson's custom knives, there is a 13+ year backlog and no new orders for knives are taken.{{cite web | last =Emerson | first =Ernest R.| title = Retirement Announcement| work = Emerson Knives Inc., News Page | date = July 1, 2000 | url =http://emersonknives.com/uncategorized/retirement-viper-series/| access-date= 2014-04-06 }}{{Citation | surname=Haskew| given=Mike| title=The Quick-Resale Phenomenon| journal=Blade Magazine |volume=33 |issue=12 | year=2006| pages=30–35 }}{{Citation | surname=Ewing| given=Dexter| title=Rock-Star Knifemakers Part 1| journal=Blade Magazine |volume=34 |issue=1 | year=2007| pages=26–29}}

= September 11 auction version =

In November 2001, Emerson made a one-of-a-kind CQC-6 and auctioned it at the New York Custom Knife Show for the benefit of children whose parents had been killed on 9/11/2001. This knife featured polished hardware, hand-checkered micarta scales, and an engraved blade reading:{{Citation | surname=Shackleford| given=Steve| title=Top 10 Most Collected Makers and their Knives| journal=Blade Magazine |volume=32 |issue=5 | year=2004| page=57 }}

"We shall strike a dagger deep into the heart of such evil".

Legacy

= In special forces =

Ownership of a CQC6 soon became something of a status symbol among members of various elite military units, including Navy SEALs, Army Special Forces, German GSG 9, and British SAS.{{cite journal |last=Lang |first=Bud |year=1993 |title=Combat Special |journal=Knives Illustrated |volume=7 |issue=2 |page=16}}{{cite journal |last=Waterman |first=Steve |year=1997 |title=Brown Water to Silver Screen: Story & Photos |journal=Soldier of Fortune Magazine |volume=22 |issue=7 |pages=67–69}}

Because of this connection to the Special Warfare community, Emerson changed the name of his custom knife line to "Specwar Knives", and in 1994 this new designation began appearing in the logo on his line of custom blades.

The CQC-6 was not an officially issued item, but rather one that was privately purchased by the troops in question.{{cite book |last=Bahmanyar |first=Mir |title=SEALs The US Navy's Elite Fighting Force |author2=Chris Osman |publisher=Osprey Publishing |year=2008 |isbn=978-1-84603-226-4}}

In May 2013, a non-custom factory-made Emerson CQC-7 knife carried by Matt Bissonnette who served as point man on the mission to kill or capture Osama bin Laden was auctioned off for charity, netting over $35,400.{{cn|date=October 2019}}
