Combative Edge’s 2013 Models

Published: May 14th, 2013 by The Edge Observer 2

Combative Edge is a gear and training company based just outside Philidelphia, PA. The M1, SR11 and SALUS designs have been informed by owner Rob Walker’s martial arts experience in FMA, Grappling and Kickboxing fitting the knives nicely into the CETERUS methodology that they teach.

Combative Edge Knives

This is the second iteration of the designs. This article will only cover the basics and design revisions. These include some changes to the folder’s mechanisms, materials for the SR11 and a new blade shape for the SALUS. If you would like to investigate the line further, the previous full reviews of the each knife can be found in the Combative Edge knife review section here.

The introductory model, the M1, is a large folder measuring in at an overall length of 8.875″ with a 3.75″ blade and and total weight of 5.2 oz. The handle is thin making it easy to carry, despite its large size. The assembly is a partially closed back construction with a peel ply G10 scale on one side, G10 back-spacer and titanium scale on the other side that includes a frame lock. The blade is a clip point with a re-curve edge and flat grind. For carry the knife has a tip up or down, right handed pocket clip and lanyard hole. Deployment is achieved using the thumb-studs or front guard (aided by a healthy wrist flick) that extends like a flipper when the knife is closed.

Combative Edge M1

The main change to the M1 is the addition of a re-designed over-travel stop. Seated against the lock arm and midway down its length, the disc is intended to help with “lock rock” while maintaining spring integrity. This was a response to some complaints concerning the lock arm of previous models. Personally, I didn’t have an issue with the originals so I don’t find a marked difference in this respect. Additionally, the clip on the originals acted as an over-travel in the tip down configuration with a U-shaped, bolt-on over-travel stop achieving the same function when the clip is adjusted to tip up. Regardless, the revised addition is a much more elegant solution. The legacy feature of the clip working double duty could probably be done away with, as it may be redundant.

The SR-11 was the second folder offered. This knife has an over-all length of 8.5″ with a 3.625″ flat ground blade and total weight of 5 oz. The profile is a unique Westernized tanto shape that has been modified with a clipped point. The handle’s ergonomics lean the blade slightly forward for improved alignment and accuracy while striking.

Like the M1 this handle is a closed back construction. The show scale has been updated with a material change from green canvas Micarta to black G10. Aesthetically this pulls the knife from being the stepchild of the line, to a matching all black and grey coloration as found on the other two products. Since canvas Micarta discolors with use, this will be a good change for users who find that off-putting.

Combative Edge Folders

The original heavily textured aluminum back-spacer makes up the handle’s spine with a titanium slab opposite the show scale. The titanium frame lock has the same update to the locking leaf as the M1 along with the older tip up and down clip/over-travel set-up.

Both Folders seem to have a much earlier lock-up than the prior version. This will allow them to wear over a longer period of time. Lock up is solid on both, but the lock face is on the sticky side.

SALUS Drop Point

The SALUS, Combative Edge’s full tang fixed blade sees the biggest modification. The blade now has a drop point instead of a Westernized tanto. The change to a more versatile pattern, capable of a wider range of jobs is a good one. Even though the Westernized tanto is designed for piercing and tip strength, the drop point’s thick .197″ blade stock will still provide plenty of durability.  Without the tip grind, the user also has the advantage of a longer continuous cutting edge.  A long swedge rounds out the geometry for effective thrust cuts.

The handle still features the same deep double finger grooves and corresponding jimped thumb ramps for either an extended or forward grip. The original G10 scales have been maintained with their heavy texture and ergonomically contoured topography. To ensure safe use there is an included wrist lanyard that can be bridged between the hole in the extended pommel and a hole in between the thumb ramps. For carry the SALUS comes with a vacuum moulded Kydex sheath nested in a nylon attachment system. This comes in a drop-leg thigh rig configuration, but can be easily adapted to a variety of carry methods via provided tek-loks or other MOLLE compatible attachment systems.

Combative Edge SALUS

The updates to the current folding models are minor and are a refinement rather than a shift in functionality. It would have been nice to see a stronger detent on the M1 to get a true flipper action out of the knife along with some treatment such as ‘carbidizing’ on the lock faces to reduce the stickiness. I would say the most significant update is the SALUS’ new drop point profile. This definitely increases the utility of the knife and will probably give it much broader appeal. While it has a distinctly ‘combat knife’ look, it would also be an excellent outdoor knife.

SALUS Sheath System

My criticisms aside, all of the Combative Edge line is capable, aesthetic and well made. The earlier models were already functional and unique, making them stand out from many of their competitors. This iteration, while for the most part making small improvements, is still a step in the right direction. Like the SALUS, it would also be interesting to see other blade profiles offered for their folders as well.

Combative Edge SALUS

Published: December 30th, 2011 by The Edge Observer 2

The SALUS is a robust full tang knife built around a 5mm (approx 3/16″) piece of Bohler N690co steel. N690co is a premium Austrian made stainless that has excellent edge retention, corrosion resistance and toughness. It can be found in many mid-range to higher end blades manufactured in Italy and is commonly utilized in hard-use knives. As a reliable performer, N690co has been the default steel for many European producers such as Fox Cutlery, who manufactures this knife.

SALUS by Combative Edge

At 5 7/8″ inches long, the SALUS’ blade has a modified American style tanto profile. Two distinct angles produce the sabre ground edge and tip, while a swedge augments the penetrating power of the clipped point. The over-all shape is very aggressive in appearance and its charcoal DLC finish seals the blades tactical aesthetic. The sum of the geometry provides a lean but ample point and a 4″ long edge for slash cuts and utility tasks. The blade is very similar to the SR11, a folder also designed by Combative Edge.

The SALUS’ handle serves to extend the utility of the knife very well. Double finger grooves are answered by a heavily jimped, double thumb ramp that allows the user to either have an extended reach, or finer control. The scales are thick contoured G10 with a deep diamond texture. A slight curve on the inside of the handle rounds out the outstanding ergonomics. The pommel is extended past the scales making it suitable as an impact tool or weapon. A hole drilled through the ridge of the thumb ramps and pommel offer lashing/lanyard options. The knife comes with a loop wrist lanyard.

The carry system for the SALUS is equally impressive. The sheath is made from two pieces of kydex and assembled with eyelets. Vacuum moulding gives the casing excellent retention and a crisp, finished appearance. Jimping on the sheath’s shoulder provides added control when drawing the blade. Slots in the kydex allow it to be attached to the suppled thigh rig with velcro strapping. The rig is constructed from rigid, plastic backed nylon. Its belt loop is extended and terminates at the opposite end allowing the cradle to be snapped onto MOLLE compatible gear. A double snap for the handle backs up the kydex retention. Two sizes of rubberized straps are supplied as well as a set of Blade Tech MOLLE locks, providing great versatility.

Combative Edge Thigh Rig

The SALUS is a complete, aesthetically appealing package. The blade, ergonomics and carry system work in concert, providing a useful, versatile, professional grade tool. This is further backed by the excellent materials used and exemplary fit and finish. While well suited for professional applications, the unique design and limited numbers will also appeal to collectors.

Combative Edge M1 Review

Published: October 18th, 2011 by The Edge Observer 6

The Combative Edge M1 is the first folder by Rob Walker for his company Combative Edge. The design leverages both Rob Walker’s long and diverse background in the martial arts and Fox Cutlery’s (Italy) vast experience in manufacturing knives. The result of the collaboration is a slim, quick deploying fighter that clearly reflects both parties history.

Combative Edge M1 G10

The M1′s blade is made from the Austrian steel Bohler N690co. N690co is a cobalt/vanadium alloy that is reported to have similar properties to VG10 in it’s hardness, edge retention and corrosion resistance but is perhaps closer to 440C in its composition. Generally users report N690co to keep a keen, durable, yet easy to maintain edge. A fact that I would be inclined to agree with, owning many N690co and VG10 knives.

The clip point blade is on the large side at 3.75″. Its “S” recurve, swedge and sharp point gives the M1 geometry that is useful in its intended purpose. The blade tang has a good sized guard which doubles to assist in opening as it protrudes as a sort of flipper when the knife is closed. It does not operate independently in design however, as the knife requires a flick of the wrist to open in this manner. Dual thumb studs will serve as the main method of deployment for the M1 and fire it open easily considering the blade’s fair size. Useful jimping on the tang followed by a dip in the spine allow for various comfortable positions in a standard grip. The serrations on the M1 are very shallow giving them an extremely aggressive bite. The blade is also available in a plain edge, both types being coated in a matte black DLC and bearing Combative Edge’s tastefully designed logo.

Combative Edge Combo Blade

The blade is met with a solid lockup and travels against sintered bronzes washers. A larger washer is used on the G10 side of the handle to allow for more mechanical durability as the M1 is a liner-less design. The ball detent is modest and doesn’t provide the strongest retention, however, considering the knives purpose it makes sense allowing for extremely easy deployment including inertial techniques.

M1 by Combative Edge

The handle on the M1 is a partially back-spaced G10 and titanium with a screw together construction. The titanium side of the grip comprises the frame lock, has the clip and a “hinderer” device in the form of a U shaped bar, attached to it. The U bar and the clip can be reversed for tip up or down carry for right handed owners. I like the feature of the U bar but think the long clip could be shortened and flattened.

The G10 slab is very grippy and has a usable scallop extending the deep, forefinger groove’s functionality. A great purchase is further established with the handle’s slight curve. Jimping on both ends provide extra insurance and helps to make the grip more confident in a standard or reverse position. The M1 terminates with a pointed pommel furthering the knife’s fighter roots, as it can be used as an impact weapon. A lanyard hole rounds out the carry options and can easily accommodate 550 paracord.

Combative Edge M1 and "Hinderer"

At a total length of 8 7/8″ long and weighing in at 5.3 Oz the M1 will be a very attractive knife for users looking for a large folder with ergonomics optimized for edged weapon techniques or self defense. Although a large knife, the M1 is quite flat and light weight making it comfortable for concealed carry. The knife’s distinct design and excellent fit and finish will also make it very interesting to tactical/martial art knife collectors.

Combative Edge SR11 review

Published: August 7th, 2011 by The Edge Observer 4

The SR11 is the latest knife by Combative Edge. Combative edge is a company based just outside of Philadelphia, PA and is owned and operated by Rob Walker. Coming from a varied martial arts background, Rob has developed his own fighting system, C.E.M.A.T. (Combative Edge Martial Arts Training) which draws from armed as well as unarmed fighting styles. His previous knife design efforts, the Salus fixed blade and M1 folder have been heavily influenced by practical experience in the martial arts and through collaboration with his peers. The SR11 is without a doubt, no exception to this rule.

Combative Edge

This is a fighting folder. After un-boxing the knife, the first try at deployment with the thumb stud(s) was extremely quick and easy. This is largely due to two factors: Firstly, the thumb studs are well away from the Micarta scale allowing for excellent leverage. Secondly, the knife uses sintered bronze washers. The washer on the Micarta side of the handle is larger in diameter. This is to help distribute the pressure on the less ridged material; a nice detail that helps with longevity as well as deployment. We put the SR11 in the hands of several people all who had no problem deploying the blade on the first try.

For the size of the blade and speed of the opening it is also notable that the detent is decent. A firm shake can open the knife but it’s logical to sacrifice some retention in the context of use.

The blade on this knife is also conducive to edge weapon combat. The 3 5/8″ inch clip point tanto is steep and sharp. It has a wide swedge narrowing the tip considerably. The slightly arched spine is followed by a shallow jimped thumb ramp. Although the point is optimized for thrust cutting it doesn’t seem overly weak, something that is helped along by the original 4mm stock thickness. The SR11′s blade is Böhler N690co. This steel is primarily used in European knife manufacturing and is the Italian manufacturing blade steel of choice. As Combative Edge knives are made by Fox cutlery in Maniago Italy (Maniago is a cutlery town and the Italian equivalent of Seki City, Japan) it is not surprising that N690co is used. Over all it is a good steel with a sound balance of hardness, durability and corrosion resistance. The SR11′s blade is finished with a satin grey DLC and is etched with the Combative Edge logo and model number. The etching has been done very tastefully, something I can’t say about most knives with etched details on the blades..

Combative Edge Frame Lock

Moving on to the handle, we find more details that speak of the knife’s utility. The curved shape provides good purchase while tipping the blade angle forward; a design choice found in many knifes influenced by Filipino martial arts (of which Rob is a practitioner of). The green micarta handle scale is heavily textured and has a somewhat crocodilian look it. The back-spacer is also heavily textured and made from black anodized aluminum. The titanium frame-lock slab is smooth allowing the knife to be presented without added resistance. The clip doubles as a stop for the frame-lock in the tip down position while a U shaped bar, when swapped out with the clip will stop the locking leaf in the tip up configuration (right hand only). This is good added function to the clip although I prefer a smaller clip length. The lack of a metal liner on the micarta scale helps to thin the knife for lighter more comfortable carry and better concealment but it also means that you might want to keep this knife away from heavy side loads.

The locking leaf has a bit of audible movement when pressure is applied toward the tang but this does not seem to effect the lock-up which has negligible play. This may effect wear, something that will need to be seen by the SR11′s users over time.

Over-all the SR11 is a well balanced knife that seems to hit its intended mark spot on. It has several features that emphasize its purpose as a fighting tactical folder and Rob’s martial art roots. The over-all fit and finish is excellent and in-line with the asking price. The design is tasteful and utilitarian without sacrificing appearance.
