In this installment of TPF, readers will be able to look at an offering by SOG which is a manual opening knife that incorporates SOG’s patented Arc-Lock system. If the title seems somewhat confusing, please do not stop reading as, despite having a long model designation, this blade does have several items that are worthy of being showcased. TPF is pleased to introduce readers to SOG’s Folding Knife Mini X-Ray Vision. This has a distinction of having a very wordy designation for such a small simple knife design that it almost seems out of place.
This knife initially appears to be one of the more basic folders offered by SOG that would be a very capable addition to anyone’s EDC (Every Day Carry) option. This knife has a combo-edge tanto blade that measures 76mm (3.0″) with some two-step serrations, one large followed by two small; repeat. The knife itself is extremely light, massing in at roughly 85gr (3.0 oz), mainly due to the glass reinforced nylon handles that surround the liners.
We here at TPF obviously love the description of this knife on the SOG website. As it resonates with the majority of our tag line.
Two words that best describe the X-Ray Vision series are “tactical” and “practical”.
But is it too fantastical for some? Some aspects may be…
As stated earlier, this knife is a manual opening knife. Manipulating the ambidextrous thumb is the primary method for blade deployment. The Arc-Lock system on the Mini-X-Ray Vision is a spring-loaded, pivoting bar that retains the blade in a closed position with minor spring force. When deploying the blade, the Arc-Lock shifts along the internal profile of the blade until fully deployed, at which time the pivot bar “locks” into a corresponding notch on the profile. The spring is the key feature for the locking mechanism, and if closed, pulling back on the Arc-Lock bar actually begins deployment of the blade. This allows for a “friction-free” deployment of the blade. However, holding the Arc-Lock bar back prevents the blade from locking open.
The two halves of the knife are held together by a quintet of Torx socket, pan head screws with the opposite side appearing as a blind rivet head. The Arc-Lock bar, and thumb studs are a two piece slotted assembly, with only the thumb stud having an exposed thread on the nut side. With the blade in the closed position the knife measures exactly 101.6mm (4.0″) to the end of the pocket clip, and when fully open the overall length stretches to a hair above 178mm (7.0″). Which will bring TPF Online to the only obvious aesthetic error that we can identify…
The countersunk flat head philips screw which is used to secure the pocket clip into position seems out of place. Using a Torx socket version would have kept up the visual appearance across the entire knife, but in the grand scheme of this knife, this is a very minor quibble. The pocket clip has a fairly large mouth and can be mounted to allow the knife to be worn on either a left or right side, tip up carry.
The lines of this knife are crisp and clean with minimal distractions, such as patterned and ornate contoured handles. The simple handle design incorporates a single pronounced finger groove. Combine that with the serrated thumb rise on the blade and the ability to control the blade for a variety of grips and uses is apparent. The pivot of this knife is very smooth, however the teflon washers do allow for a slight amount of blade play side to side.
The blade itself is manufactured from VG-10 steel, with a thickness of 2.5mm (0.10″) and has a bead blasted finish. This steel is normally considered to be a higher end steel that has good qualities regarding corrosion resistance, edge retention, and sharpening ability.
The Mini X-Ray Vision, SOG Model #MXV72-CP, is a very lightweight manual folding knive with a higher quality steel blade. Readers may recall earlier in this write-up we commented on the possible fantastical aspect of this knife. The suggested MSRP of the knife as reviewed is $161.50 USD, but readers can find it at a much more affordable price point at various online outlets across Canada, such as Blades Canada Cutlery Corp., who have a storefront in Vancouver BC. As an EDC knife, this edged tool has all the required options for being a good EDC, possibly excluding the price tag. However, as per the norm for here, it is up to you, our readers, to determine if SOG’s Mini X-Ray Vision falls under the heading of Tactical, Practical, or Fantastical.
One of the most abused parts of a knife is the point or tip of the knife. Users jab it into seams and use the blade as a makeshift wedge or pry-bar in order to crack open or split whatever they are working on at the time. The problem is that the tip of the knife is the weakest part.
The prying puts large tangential stress into a small focused area on what is traditionally the thinner parts of a knife. Now, several knives try and offset this by making a blunt tip which increases the area used for prying that distributes the fores better. Others increase the blade thickness to have a stronger tip that can suffer greater levels of stress before breaking. Columbia River Knife and Tool had a slightly different take which makes a bit more sense to the author. Enter the Barge.
Kershaw’s Barge is a very simple and rugged designed knife that has basically two purposes. Cutting stuff and being used as a wedge/prying tool. The knife is not really that small, amassing just over 150g (5.4oz) and measuring 119mm (4.75″) in length when closed. The first thing you notice looking at the knife however, is the huge metal cap on the knife’s butt end. That is the key of the Barge, the wedge shaped butt cap, and it is massive and mounted very securely between the liners. The wedge acts as the spacer between the two liner halves of the knife. It is secured by five (5) screws along the back and rear edges of the handles, these are not small screws either, they are massive compared to those typically used on folding knives. Of interesting note of this design is the fact that the majority of the screws/nuts use a T8 torx driver for assembly/disassembly, with two exceptions. The reversible pocket clip allows for both left and right handed, tip-up carry, and is secured by a pair of T6 torx pan head screws. The second exception is the most obvious and greatest departure from the other fasteners used, as the large pair of slotted screws provide the main strength that binds the handle to the wedge. The wedge also has a lanyard opening for those who desire to use them.
From the Kershaw Website:
- Multifunction – Has multiple blades or tools, enabling it to perform multiple functions.
- Manual – There is no mechanical assist, such as SpeedSafe, used to open the folding knife. It opens the classic, old-school way.
- Frame Lock – A portion of the handle (the knife frame) moves behind the blade to lock it into position during use. This is a safety feature of the knife.
- Reversible – Pre-drilled holes in the handle enable the user to change either the tip position or the side on which the knife carries.
As is typical in many frame lock knives that are manual in opening, there is a small bearing that is press fit into the locking arm and a corresponding dimple/hole in the blade that enable securing the blade into a closed position. This does equate to a very slight increase of required pressure when opening these knives, but it is almost negligible when using the thumbstuds to open the 6.6cm (2.6″) edge. Now speaking about edges, the Barge’s plain blade has a slight hollow gound edge whose profile is a combination of a warncliffe edge with the spine of a typical drop point and incorporates a slight upward curve close to the tip. Manufactured from 8Cr13MoV, the blade is easily sharpened, and the blade itself, the frame halves, and the wedge have been given a stonewash finish which gives a soft, metallic appearance.
The overall length of the wedge insert is 66mm (2.6″) and is scalloped to allow for the knife’s blade to easily fold up while creating a very robust assembly. The steel right frame panel is 2.4mm (0.095″) thick and incorporates the frame lock mechanism, whereas the the left panel is slightly thinner at 2.0mm (0.08″). However a black textured nylon panel completes the left side for added grip. The blade is 3.1mm (1/8″) thick and uses nylon washers for stiffness and rigidity at the pivot point. The Barge measures 12.1cm (4.74″) long when closed and 18.4cm (7.24″) when locked open which belies the 146.8grams (5.18oz) that this hefty tool masses. The wedge of course is a large contributing factor in those numbers, and with a 1.7mm (0.67″) thick flat edge that is 10.0mm (0.40″) long, the “screwdriver” tip of the Barge is ready for some of the worse pry jobs most people can imagine.
The Kershaw Barge, model 1945, is a very utility oriented knife that could be a good addition to an individual’s every day carry inventory. With a noticeable mass and good control surfaces, this offering may seem cheap at the MSRP of $48.99 CDN, and can be found in stores such as House of Knives. As always however, the question is what category the Barge falls into for you, the reader? Tactial? Practical? Or Fantastical?
