Gear Review: EDS II Screwdriver and EDC Wrench from BIGiDESIGN

BIGiDESIGN is producing so many awesome EDC tools, and in this review we are taking a detailed look at the BIGiDESIGN EDS II, the second, updated version of their unique Everyday Screwdriver, along with the BIGiDESIGN EDC Wrench a reimagining of an antique Swedish adjustable wrench.

Their original EDS, Everyday Screwdriver, was probably the first BIGiDESIGN product that I saw, and since then I bought their bolt action pen, a design that ingeniously adjusts to take most ballpoint refills on the market. Now I’ve been able to partner up the Bolt Action pen with the EDS II and EDC wrench making for an incredible EDC setup.

Video Overview

In this video we take a good look at a couple of lovely EDC gear designs from BIGiDESIGN. The EDS II, the second, updated version of their unique Everyday Screwdriver, along with the EDC Wrench, a small unique pocket friendly adjustable wrench.


What’s in the box; Part 1 the EDS II?:
For the three BIGiDESIGN products I have, the packaging follows the same layout. A slide out tray which has a compartment at one end that contains spares.


A good look round the EDS II – Things to look out for here are:
Overall layout of the EDS II is of an integral lock folding knife, but with a bit holder instead of a blade. A single thumb stud means this easier for a right-handed user. Explained in more detail in the video, there is a stop pin that both stops the bit holder arm in the right position when open, and also stops the spare bits sliding out of the front of the storage slot. The other end of the spare bit storage slot has a sprung ball to keep the bits in place. The integral lock action is easy to see as the bit holder is unfolded. Several magnets are used for keeping the spare bits in place and the main bit holder folded. In the EDS II an additional spare bit holder has been integrated into the lower section of bit holder arm. A total of four bits can be carried within the EDS II.


What’s in the box; Part 2 the EDC Wrench?:
Again, following the format of the other BIGiDESIGN products I have, the box has a slide out tray which includes a compartment at one end that contains spares.


A good look round the EDC Wrench – Things to look out for here are:
A reimagining of an old Swedish design, there is a sliding adjuster moved by a worm screw. BIGiDESIGN have added both a metric and imperial scale for setting the wrench ready to use. A low profile clip is fitted to the back and the EDC Wrench also includes a Ti bead on the lanyard. You can just see the slider retainer under the clip.


What it is like to use?

BIGiDESIGN have done something really special with the EDS, and now this updated EDS II, and given you not only a new experience of using and carrying a screwdriver, but one that is very practical as well.
It is not the smallest EDC bit holder available, nor does it include a ratchet, but instead it gives you a highly usable screwdriver with integrated bit storage for a total of four bits without needing anything else.
Having a swing-out bit holder extension arm, the EDS unfolds to a very practical conventional structure of handle, shank, and bit, so compared to many other small EDC screwdrivers it gives you a more usable tool.

That genius part of the design is mimicking an integral lock folding knife, having a thumb stud to swing the bit holder arm out of the folded position for one-handed operation. So satisfying to use!

However there is a little observation to note about how easy or difficult it is to open the EDS II. The arm’s retention in the folded position is due to a magnet in the body grabbing the bit that is in the bit holder. As you use the EDS II and swap bits around, you will find that a bigger bit, like the full size flat bit, is held by the magnet more firmly, so firmly it becomes very difficult to open using the thumb stud. Put a smaller bit into the holder and it becomes much easier to open again. So the bit you leave in the main bit holder arm changes the ease of opening the EDS II. I would have preferred that the arm retention was a detent (like a knife would use) or that the thumb stud had a bigger cut-out round it allowing more contact and an easier open.


Onto the partner tool here and the EDC Wrench, an infinitely more pocket friendly design than a standard adjustable wrench, there was one big flip for me, literally, in how I envisaged using it before actually getting my hands on one. That is the fact that with the adjustable slider being very much on one side of the tool, to use it and make contact with the nut, you have to flip it over so the ‘front’ of the tool is away from you (pocket clip towards you). Like this you can’t see the scale, and initially it just felt a bit odd, but is just how it works. Even with larger nuts, all except the very largest, you need to use it this way round.

Being a ring spanner, you do have to be able to pass the ring over the end of the job onto the nut, so can’t be used for certain jobs. If you hit those limits though, it is less likely an EDC type of job, so then you bring out the full size tools. Know the limits of your tools and don’t abuse them and you’ll get along just fine.


Talking of limits, and pushing them, the EDS II and EDC Wrench can nicely partner up for a bit more screw driving torque. There is just enough of the 1/4″ hexagonal bit showing to use the EDC Wrench to grip this and boost the turning force for stubborn screws. Not always possible, but if you have the space, this can save you having to go for bigger tools. In this case the EDC Wrench is used with the slider facing you as it needs to be this way round to grip that small section of the hex bit.

Both of these beautiful EDC tools are made from grade 5 titanium alloy and punch well above their weight, even more so together.

Knife Review: MKM Hero

Join me in this review of the MKM Hero as we take in all the details of this superb new folding knife designed by Tommaso Rumici. Working with MKM (Maniago Knife Makers) Tommaso has focused on usability and versatility in a design that specifically delivers the ambidextrous features a real working knife needs.

Video Overview

This video includes a close look round the Hero, and then onto the measurements and specifications.


What’s in the box?:
The Hero arrives in what initially looks like a simple storage pouch, however, on the back are a couple of belt loops, meaning the pouch is actually a horizontal belt pouch as well. Within the pouch is a pocket that has a double-ended T6/T8 torx wrench and leaflet.


A good look round the Hero – Things to look out for here are:
The version of the Hero in this review has the marbled carbon fibre handle. The liners and integrated bolsters are milled from one-piece of titanium with the handle slabs set into them. Cut into the reversible titanium clip is MKM’s distinctive mountainscape logo. The clip is held in place by two torx screws, making it easy to reverse the clip.
Double-sided stepped thumb studs allow ambidextrous blade opening. Choice of the back-lock is another intentional ambidextrous design feature. Jimping for extra thumb grip spans the blade and lock bar.


The Blade and Handle – Detailed Measurements:
For full details of the tests and measurements carried out and an explanation of the results, see the page – Knife Technical Testing – How It’s Done.

The blade is made from M390 steel.


What is it like to use?
I had the good fortune to be introduced to the Hero by its designer Tommaso Rumici, and get a run down of the features directly from the horse’s mouth. To my amusement, with this demonstration coming near the end of IWA 2022, and hands being well sanitised, and dried to a crisp, I managed to crack my thumb open on the Hero’s thumb stud and bleed all over the blade without actually cutting myself on the edge.
As I have got to know the Hero, there is one aspect I’m not so keen about, and that is that the thumb stud is a little on the pointy side. You do need to be careful to press onto the side of the stud and avoid pushing straight onto it to swing out the blade.
A good back-lock makes for a supremely practical layout in an ambidextrous focused knife. Unlike liner or integral locks, which are handed, the back-lock is predictable, reliable and absolutely identical in operation regardless of the hand holding the knife.
Where a lot of the design intent shows through is in its handling, and we must talk about the Hero’s handle. In terms of width, the Hero is actually pretty slim, so is nicely low profile in a pocket, but the depth and generous swell/hook at the butt of the handle is where the huge flexibility of grip positions and fantastic grip stability comes from.
For really controlled work, you can choke right up on the handle and place a finger on the guard/bolster bringing you to the cutting edge. At the complete opposite extreme grip position, taking a hold when you might want to use a chopping motion, thanks to the grip swell, you can take a secure grip of the very end of the handle with your first two fingers without worry of losing your hold on the Hero even when striking down with it.
Then you can take the middle ground with a standard grip and rest your thumb on the jimping that spans the end of the lock bar and blade for control and cutting force. When using this grip position, you can alter the angle the blade is presented by changing the pressure of your little finger on the butt hook. Doing this makes the knife swivel about your first finger, opening out, or closing in the position of the blade relative to your hand and making the blade extremely agile in use.
Exactly as intended, the Hero is big enough for most EDC tasks, and most general purpose jobs, yet not too big to put you off carrying it.
