Review: restored Folding entrenching tool

 A couple of years ago, between lockdowns, I went for a bushwalk with the family, in the Churchill National Park just near my parents place, and on the way back we passed a couple of items, sitting rusting beside a tree. I'm a firm believer in the old Marine adage of "Gear adrift is gear a gift", and as it had obviously been left in the elements for some time, snapped them up. A good sized Dutch oven, and a wooden handled cast iron pot with lid, and beside them: a rusty entrenching tool. After some soaking, scrubbing, heat-cleaning and re-seasoning the pots have become a welcome addition to my outdoor cookware collection.

The entrenching tool appears to be a Bushtracks folding entrenching tool with Pick' which had seen better days. The screw-down locking bracket had partially seized but with a little elbow grease and liberal WD-40, I got it worked loose enough to unfold the shovel-head and the pick head, with a little extra work I cleared the screw threads of grit and get it working smoothly. 

The next step was to wash and scrub the rusted  shovel face and pick. Luckily the hinge and locking bracket were not especially rusted. Once the loose crud and dust was removed, I heated the shovel head over the gas range hood to drive off any remaining moisture and coated it liberally with linseed oil as a seasoning mechanism. I did this outside as the hot steel vaporized the oil into old-timey smelling white clouds.

The scrubbing and seasoning paid off  and the surface has remained rust-free despite quite a lot of digging, both in the garden and trips to the beach where I use it to fill ballast sand-bags for our sun shelter. I have previously reported on my black tri-fold e-tool and the much smaller tactical-dump trowel but i'll be comparing the two e-tools, as they're in the weight-class.

I'll start by breaking the tool down into its major elements: the shovel, the pick and the haft. 

The working end of the shovel is a triangular tipped square side shovel, with  a gentle scoop. The tip is rounded and the edges are quite wide for durability, unlike the tri-fold which has a decidedly sharpened edge. One of the square sides has a sawtooth edge cut into it. The shovel face is riveted onto the hinge piece with three hefty rivets. The shovel has three positions, folded flat, 90 degree "Pick mode" and full extension. when folded flat the "head" of the shovel between the rivets makes a half decent hammer face, perfectly suitable for driving tent stakes in, not so much for fine carpentry. 

The screw-down locking bracket features  a big washer to aid in keeping  a tight fit when tightened which has stood up to some enthusiastic hammering and digging.

When folded out in "Shovel mode" the tool stretches to a fairly decent 62 cm (24 2/5") length, slightly longer than the delta-handled tri-fold. Length is leverage and leverage is force, both have utility when digging, and the extra length has little impact on its pack-ability  at 42cm (16 1/2") fully folded.

The shovel face itself a little smaller than that of the tri-fold,, but the tri-fold has an inch or so "behind the shaft" so the usable length is all but the same. it certainly digs well and scoops tailings out of the way smartly.  It lacks as pronounced  a rolled-over back-edge to support a diggers boot-assist, and if you really wanted or needed to you could use the pick, folded down.  

At 860g (lbs 14oz) its a reasonable tool to carry around, especially if you know you'll need to dig more than a trowels amount (be it a fire-pit, latrine pit-trap or fighting position.) The wide edge does not lend itself to axe-like chopping in the way the tri-folds per-sharpened edges do ,though they could take an edge without too much effort (either hand file or powered grinding tool). The saw teeth could be sharpened up without degrading the robustness of the tool, but that's a project for another day. I have been primarily using this in the vegetable garden, tilling soil, digging up potatoes and shifting delivered soil into our raised beds.

The Pick tool folds and locks in place the same way as the shovel does. The most useful position being at 90 degrees to the haft. The spike itself is curved along the whole length of the pick for strength and extends out  21 cm (8 1/4") from the haft. 

It is possible to operate the tool with both shovel and pick extended, but its a bit cumbersome. Easier to use one tool and swap between the two.  The pick isn't sharp-tipped, featuring the same robust edge as the shovel, but its not expected to be a mining tool. 

The pick, when folded flat against the haft, can also serve as a hammer, though the rounded back face of the pick makes for a tricky strike surface, but possible.

The pick can also be folded "upwards" into a "spear" configuration, extending the tool into a length of 58cm. Good for getting to the bottom of a hole, reaching the top shelf or possibly ventilating an unwanted visitor to your trench.

Lastly, this tool can, when set into soft enough soil, make for a halfway decent stool, with some balance and practice. better than sitting in the dirt or mud, not as good as a proper chair. 

The original haft was held in place by a rivet through the throat of the locking bracket, and whilst giving the tool a good bash test, trench-club style, I managed to snap it off at the bracket. After sitting unloved in a pile of scraps for half a year, including a house move, I dug it out, ground down the rivet head with an angle grinder, whittled a new head to the shaft, fitted it after a little char-hardening and set it with a clinch-nail. This cost me 2-3 inches of over-all length, but with my longer than average wingspan, it's none the worse. 

Though it doesn't fold down as small as the tri-fold, nor stow away in its own belt pouch (though military surplus canvas pouches exist), this is a solid tool rich with utility and with years more life in it, both in the garden and on the trail.

At some stage I may throw a sharp edge on the shovel for root/brush chopping and i'm certainly going to try my hand at sharpening the saw edge, but all in all I'm very happy with this restoration and salvage of a "lost" tool.

For the God-Emperor! For Krieg!

Nano Oil for your Knives, Tools, and Firearms

Another Guest Author, by way of BB&C,  Jim Davis presenting Nano Oil:

Always on the lookout for cool, different ideas, I happened upon a product that caught my eye. Not just for the content of what's in the containers, but the way the containers deliver it to the target. Nano Oil offers some unique and innovative methods of dispensing lubricant onto firearms, knives, and anything else where you want to deposit a controlled amount of oil into a small space.

They have a few various dispensing containers that I'll outline here.

Nano-Oil comes in handy, syringe-like containers. Here is a package with three different weights: 5, 10, and 85 weights.

What Is It And What's It Good For?

First, though, a bit about Nano Oil. It does not contain any of the following: Silicone, PTFE Resins, Graphite, Molybdenum Disulfide know as Moly, Teflon, Copper, Lead, or Silver. They state that there are "absolutely no metals or harmful solvents."

StClair claims that Nano Oil is suitable for high temperature applications, extreme pressure (load bearing metal to metal), roller bearings, chains/sprockets, machine tools, marine equipment, metal working, mining and printing equipment, armaments, knives & multitools, and a ton of other uses. The list is quite expansive.

It works on bicycles, motorcycles, cars, tractors and farm equipment, and RC racers.

Regarding armament, they claim that it increases muzzle velocity and smooths all moving parts while protecting from rust and corrosion. The oil adheres to microscopic crevices and penetrates metals, which provides a very low friction dynamic.

Weights

There are a couple different weights that are offered for various uses.

*5 Weight. This is the lightest weight oil that is offered, noted for deep and fast penetration. They refer to it as "WD-40 on steroids."

*10 Weight. This is a light weight oil that is suitable for guns, flashlight threads, knives, fishing reels, locks, hinges, bicycles, bearings, cables, chains, sprockets, motorcycle forks, electric motor bushings, model railroads, and more. This one seems to be the most useful weight, in general, as it addresses a lot of different uses.

*85 Weight. This is a heavy weight formulation, developed for the M-14/M-1A and other rapid fire firearms.

I ordered and received one each of these weight lubricants in the Micro Oiler with stainless blunt needle, which contains 8cc/ml of oil. These are extraordinarily handy because that needle can get the lube precisely where you want it. Note that the same weight oils can also be had in 1/2 ounce and one ounce bottles.

One of the beautiful aspects of Nano-Oil is the blunt metal applicator tip that allows the user to get the oil where it needs to go. These are the micro oiler containers.

I also received an applicator of Nano-Grease NGL, which is a Lithium Complex Hi Temp & Extreme Pressure lubricant. The uses for it include bearings, boats, buses, cars, bicycles, chains, conveyors, dozers, excavators, graders, laundry equipment, and a bunch of other items. And since the M-1A/M-14 series of weapons are supposed to be lubed with grease, that was my main intention of buying this, as I am using it with my M-1A Scout Squad Rifle.

With the grease syringe, getting into the chamber area of the M-1A Scout Squad Rifle a snap.

Greasing up the operating rod on the M-1A is no longer difficult either.

Nano Oil states that adding its formulations to other existing lubricants will improve their anti-friction qualities.

I have not tried the following, but they are listed on Nano Oil's website:

Gasoline Engine Oil Treatment, Diesel Engine Oil Treatment, Manual Transmission Oil Treatment, 4-Stroke Engine Oil Treatment (Motorcycle, ATV, Snowmobile, Outboard Motors), Small Engine 4-Stroke Oil Treatment, Automatic Transmission Oil Treatment, and Marine Outboard Drive Treatment.

Dispensers

The first is a pen that has something similar to a ball point. The user presses the tip onto the surface where he wants to deposit oil, and the oil comes out. It's fairly controllable too, so you can get a small dot, a larger puddle, or a line. The pen container I received contains 16cc is 10 weight oil, which is listed as "All Purpose." I'd say it would work great for firearms, knives, and anything with moving parts in general. The cap even has a protrusion for hooking onto the user's pocket, so it can be conveniently carried anywhere. The container is white and not see-through. At the time of this writing, one of these pen dispensers costs $27. It appears that it should last quite a while.

The pen is a very handy container to have around!

The tip of the pen is similar to a ballpoint pen, in that when the tip is pressed, it dispenses oil. The user determines how much oil he wants to come out.

The next type is a Micro-Oiler, which is see-through and has a long, blunt, metal needle for getting the lubricant just where you want it.  This is especially useful if oiling knives and firearms. Normally, I run my knives dry or nearly so because oils tend to attract dirt and other gunk. The 5 Weight oil will be especially useful for knives because when it dries, it leaves very little residue behind, yet still retains lubricant qualities. This is good stuff!! A 3-pack of these dispensers with 5, 10, and 85 Weight lube, at the time of this writing, costs $49.00. At the rate in which I use lube, I believe these will last me for quite a while.

Finally, the grease dispenser is like a giant syringe that comes complete with a long, blunt metal needle, which gets the grease into those hard-to-reach places. This is especially useful when applying to the M-1A rifle, as it allows the user to get the grease into the areas where the bolt rides in the receiver. Those little grooves can be a pain to reach by other means, but with this setup, it becomes very easy. At the time of this writing, this one costs $21.75.

The grease syringe has a large volume and the metal tip is perfect for getting the grease where you need it to go!

Does It Work?

Naturally, I went totally overboard trying Nano-Oil out on most of my firearms. Those that know me will not be surprised, as I tend to go all-in on my endeavors.

So far, I've used Nano-Oil on my S&W CSX 9mm, S&W Airweight .38 Special Revolver, Glock 43X, Ruger MK IV .22 Long Rifle pistol, Two AR-15s, an AK-47 (AK-63D) Underfolder, and my M-1A Scout Squad Rifle from Springfield Armory. I plan to use it on my bolt action rifles and my Henry Arms Survival Rifle (AR-7). In other words, I will use this stuff on all my firearms and knives.

 

This AR pistol by Xtreme Gun Worx (of Emmaus PA) and the AK-63D Underfolder benefitted from an application of Nano-Oil.

The pistols that I tried Nano-Oil on, from top to bottom: Ruger MK IV .22LR, Glock 43X, S&W CSX, S&W Airweight 642 .38 Special revolver. They all said they liked Nano-Oil!

Speaking of knives, I've used it on my Emerson Knives Desert Roadhouse. Some of my Spyderco folders will also see Nano-Oil. The nice thing about the 5-weight oil is that it dries up and doesn't leave a gunky residue on knives, but the lubricating benefits still remain.

Getting oil into specific points of a knife action is now easy! Here we see the Emerson Desert Roadhouse getting some care.

I can honestly say that Nano-Oil is good stuff; my firearms' actions were nice and smooth after using it on them. So the quality of the oil and grease itself is sound. Beyond that, what I really found refreshing is the applicators that come with the oil. These really made all the difference when I used them to apply the oil, and they made the job so much easier on most of the guns.

Glock 43X frame rails getting a dose of Nano-Oil. Nano Oil is an obvious choice for gun care, but works well on a variety of other things as well - particularly knives and tools. 

And don't forget the inside of the slide where parts create friction.

Those hard-to-reach places that used to be a pain to get oil into now are easy to reach, so I expect this will improve the reliability and longevity of my firearms.

The Ruger MK IV bolt being coated with 10-weight Nano-Oil. Getting oil inside the receiver is now easy as well.

A special mention here goes out to the Nano-Grease. Applying it to my M-1A Scout Squad rifle is so much easier than trying to get grease into the area where the bolt goes than using a Q-tip. The metal syringe tip placed the grease precisely where I needed it, not only for the channel where the bolt goes inside the chamber and on the receiver, but also onto the operating rod. Kudos to Nano-Oil!

The M-1A Scout Squad Rifle from Springfield Armory is basking in the glory of being freshly lubricated by Nano-Oil.

The Ruger 10/22 will function smoothly with Nano-Oil applied. This is the compact model.

As well, applying it to knives also becomes a breeze, getting the oil in those hard-to-reach places without saturating the entire action of the knife in oil. The user has good control over how much oil comes out of the needles.

All in all, Nano-Oil has a successful product that really delivers (no pun intended). The price is not too high for what the user gets, and the supply should last quite a few cleaning and lubes for one's firearms. This is a great product that I wholeheartedly endorse.
