Strike Industries recently brought out their Dual Folding Adapter. It is a unique folding stock, or brace, for mounting on a picatinny rail, hence the “adapter” part of the name. From pistols to rifles, the Dual Folding Adapter (DFA) has a variety of uses.

The Dual Folding Adapter comes with everything needed for multiple mounting options. It comes in the box set up to be used as a pistol brace. Also in the box is a buttplate. The buttplate is to use the DFA on a rifle or registered Short Barrel Rifle (SBR). Do not put the buttplate on the DFA while it’s on a pistol. The buttplate also has a rubber buttpad attached to it. To mount the DFA to anything, you need a firearm with a rear vertical picatinny rail. Then you just slide it on the pic rail, insert the screws, and tighten it down. The stabilizer has a QD socket at the top rear, for use with a single point sling. This lets you put pressure against the sling, to help stabilize the pistol. The buttplate is pretty explanatory for a rifle. The buttplate also has 2 QD’s, one on either side, for mounting a sling. To switch between the buttplate and the stabilizer, there is a torx head screw that goes through the end of either one of them, and screws into the strut.

Now for the best part. The Strike Industries Dual Folding Adapter folds both ways! There are 2 buttons on the top, by the picatinny rail mount. These buttons unlock the DFA so it can fold. If looking at it like you hold a pistol or rifle, push the left button down, into its recess, and the DFA can then be folded to the right. Or, push the right button and it can be folded to the left. The DFA has a slight 3 degree downward angle, when folded. This is to help clear ejection ports, so that a rifle can still be fired with the DFA folded. To unfold the DFA, you have to push up slightly and then pivot the DFA out to lock it in the unfolded position. If you push up by the stabilizer or buttplate, nothing happens. You have to push up closer to the hinged portion, or the DFA won’t unfold. I like how this worked because you aren’t accidentally unfolding the DFA. It is also really easy and quick to unfold the DFA. Just push up a little with your thumb and you are in business. There is a small price to pay for the ability to fold both directions. That comes in the way of the picatinny rail mount and folding mechanism. The folding mechanism is 2” wide, so it is the widest part on the whole DFA. One typically mounts the DFA up by the firearms receiver, so it’s not as bad as it sounds.

Other than the folding point, the Dual Folding Adapter is quite slim. The strut on the DFA extends rearward from the folding mechanism, it has some lightening cuts and is only about ½” wide. The whole DFA weighs under 10 ounces, so it’s not heavy at all. Total length on the DFA is about 9.25”. In the folded position it adds, a tiny bit over, an inch to your firearm. If, for some reason, you want to take the DFA off, you can push both the buttons and slide it off of the picatinny mount. Why, I am not sure, because it folds. Strike Industries also sent me out their Cheek Riser. This is for using the DFA as a rifle stock. The cheek riser clamps on through 2 holes in the strut. It has 3 height positions. The cheek riser makes the strut much more comfortable to lay your cheek against. Plus those height adjustments let you get your eye in the right spot for your optics. I was impressed with how comfortable and useful this little piece of polymer was.

The Dual Folding Adapter was used mainly on a Strike Modular Chassis. So it was used in the pistol stabilizer configuration. I was pleasantly surprised at how well the DFA stabilizer brace worked for me. It rested nicely against my arm and really did help stabilize the pistol. There is a tiny bit of up down movement in the whole system, but it’s less than some M4 stocks, so no complaints about stability. Speaking of stability, Strike Industries has little rubber bumpers that go inside the DFA to help with lockup and cushion the impact of that lockup. I ended up using the thickest ones provided, as they gave the best feel and tightness. I probably have opened and closed the DFA more than I should have. It’s kind of a fidget spinner for firearms.

If you happen to be in the market for a folding stock or brace, why not let it fold both ways. The Strike Industries Dual Folding Adapter does just that. It makes an excellent stock, as it is sturdy, and it really shines as a foldable brace. Strike Industries has really stepped up their accessory game in the last few years, The Dual Folding Adapter is definitely one to check out.

Medford Knife & Tool is a semi-custom knife shop in Arizona. I say semi-custom because every knife leaving the factory is ground by hand. These knives are not what you find at the local sporting goods store. I talked with them at Blade Show West last year. A few weeks later they said they would send something to review. I was really happy when the “Proxima” showed up.

Wow, what a knife the Proxima is. The first thing I noticed was the heft. It really isn’t too heavy at 8.2 ounces on my scale, but it is stout. Medford shipped this knife in a plastic, reusable, waterproof case also. Along with it came care, maintenance, and break in instructions.

The Medford Proxima is a flipper style knife. So on the back of the handle sits the flipper. The flipper is attached (built on) the blade. By pulling it backwards, it “flips” the knife open. Medford designed the proxima to be smooth, but still have resistance. So I have to flick the flipper pretty noticeably to kick the knife open. They don’t want the blade so loose that it just falls open or closed. There is also a a recess cut into each side of the blade so you can open it with your thumb, or as one would with a regular folding knife. The flipper also has grooves on it to give your finger some traction while “flipping.” Once the knife is open, the flipper doubles as a guard to keep your hand from sliding forward during stabbing motions.

Construction of the Proxima starts with the blade. Medford uses S35VN Stainless steel as blade material. The S35VN steel gives the Proxima excellent strength, edge retention, and wear resistance. This does make the blade a little harder to sharpen, but it is well worth it. I have not sharpened my blade, and it is still very sharp after 6 months of use. The blade is of the drop point style with a false tip. But even more important, is that the blade is 3/16” thick and almost 4” long! The false tip gives the blade a nice point. Every blade at Medford is ground by hand and the Proxima is no different. The hollow grind looks beautiful and allows years of sharpening before the blade edge gets really thick. I am also impressed with how the tumbled blade looks. It is not polished, but not dull either, just good looking.

Now onto the Proxima’s frame. The frame is the other part in what makes a knife, a knife. Starting with titanium as material, this particular knife has some faded anodizing. The non-locking side has a purplish-blue fade to a bronzish color on the inside. On the locking side, which is a standard style frame lock, it has a solid purplish/bronze color. Both sides are also tumbled, and not polished. This makes for a really nice looking knife. The non-locking side also has some grooves and a finger cut-out for a good grip. The locking side also has some grooves on the lock, both for increased grip, and too help with unlocking the blade. There is also a hole for attaching a lanyard, if that’s your thing.

This particular Proxima uses Stainless Steel hardware. Other options (colors, materials) are also available. The hardware is basically the spacers and screws that hold the knife together. It’s functional, and that is all that really matters. The pocket clip could also be included as hardware, but the standard clip is brushed titanium and held on with 2 screws. This clip is probably the stiffest clip I have ever used, and I love the amount of tension it has. This is where I have a slight flaw with the knife. The clip can not be moved, it comes in a tip-up position. I would have at least liked another option for if you carry it on your right side. The only problem I have had with the knife also includes the clip, it came loose on me after about a month. I put medium strength thread locker on the screws and have not had a problem since.

When I go to use the Proxima, it just works. I just flip the blade out, it opens smoothly, and start cutting. The handle shape and size let me get an excellent grip if I need to do some real work. The spine of the blade also has some gimping that helps me get good downward force with my thumb. The flipper does stick out a bit, but that’s what makes it useful for me. I’ve cut everything from packing tape to pallet strapping (the plastic type) and the knife still cuts great. I expect the Proxima to last me around 5 life times, it is built that stout.

So, if you are the type to use or buy $500 knives, definitely go check out Medford Knife & Tool. This Proxima is built like a tank. It is all US made and built by actual people, not just machines. I am not one to spend this kind of money on a knife, but after seeing and using the Proxima, I see why someone would. Go check MKT out, they have some really cool and functional knives.
