Update: WTF mini wrench and pry bar

A little while ago I reported on my pre-release WTF Ti mini-pry bar that I managed to sweet talk Brad of TacticalKeyChains into sending me, as it was a second. Just recently my full order from the Kickstarter campaign arrived, and thought I should show off the pre-production version against the production models.

 I ordered both titanium and the chromium/molybdenum  chromoly 4130 steel "stealth" version which has been Parkerized for shine and corrosion resistance. The main physical difference between the Ti and chromoly is the machining, in that the face of the pry-edge of the Ti versions is textured from the machining, where as the chromoly  version is smooth finished, due to the requirements for working the different metals. I like them both, and have had no discernible difference in performance when prying, they both bite nicely.

I had the production WTF anodized to a rose-gold colour, as it was going to be a gift for Omega (which she put straight onto her key chain, along with her NuKo Tool TiGBi Skully ). The only real difference between the the production version of the Ti WTF, and my "seconds" version is the lanyard hole is not quite centered in the second. In theory this might weaken that end, but I can't imagine putting enough force on the lanyard hole to make that an issue.

The Ti WTF's (made of Ti-6Al-4V) weigh 7.8g and the Stealth WTF (made of AISI 4130) weighs more at 11.5 grams, which is a small price to pay considering the benefits.

Brad has kindly provided some metallurgical stats on the materials he uses for the WTF's. The Ti-6Al-4V - has an Ultimate Tensile Strength of 138,000 psi and an elasticity modulus of 16,500 ksi, which means it is very very resilient, and springy. It will flex under stress.
TheChromoly 4130 has a Ultimate Tensile Strength - 97,200 psi but has an elasticity modulus of 29,700 ksi meaning it is not quite as resilient but VERY stiff.
Compare that against the aluminium 6061-T6 used for the basic WTF's which has an Ultimate Tensile Strength of only 45,000 psi and an elasticity modulus of 10,000 ksi  which is to say, relatively soft.

The cromoly WTF has the advantage of being ferromagnetic, and the wrench bits will not "give" when working stubborn nuts.  I really like my WTF's, i wear the golden "second" around my neck as a part of my EDC, and the chromoly version has found a place in my ZuluNylonGear CAOS admin pouch. These are brilliant little tools, and I'm glad I made the investment. 

Review: WTF - Ti wrench and pry tool

More Kickstarter goodness.

I managed to snag a "second" as an early trial piece for the WTF mini titanium keychain Kickstarter, from Brad, creator of the Bottle Grenade "the-last-opener-you-will-ever-need"

I am always on the lookout for little tools liek this, because I really like having them on hand, in my pack, in my EDC, without being totally overburdened (don't laugh).

This one was a "second" as it was slightly mis-aligned, you can see that the internal cutouts are not quite centered, leading to a slight reduction in strength, so when they were offered for immediate discount sale, i snapped one up.

The Kickstarter project offered these in three materials and I pull directly from the Kickstarter brief for these:

Aluminum 6061-T6 - Ultimate Tensile Strength is 45,000 psi and an elasticity modulus of 10,000 ksi (Soft) ~4.4 grams


Titanium Ti-6Al-4V - Ultimate Tensile Strength is 138,000 psi and an elasticity modulus of 16,500 ksi (Springy) ~7.8 grams

and finally a Parkerized Chromoly 4130 - Ultimate Tensile Strength - 97,200 psi but has an elasticity modulus of 29,700 ksi (Stiff) ~11.5 grams (and a Rockwell hardness of B 90–96 holy crap!!)

I opted for a Ti and a Chromoly, but they aren't expected till November (6 months away, I might DIE) so was thrilled to get this little guy in my hands.

Brad even zipped it though his anodizing mix, and I got to select my colour, this is the 55VDC anodizing and it gave a lovely pale gold colour to the tool.

So, what does it do?

The dimples on the sides correspond to 1/4"  on one side, and 1cm on the other.

The middle cutout features the following sockets:
Standard: 1/4", 5/16", 3/8", 7/16", 1/2"
Metric: 6mm, 8mm, 10mm, 11mm, 13mm


I actually struggled a little while to find some bolts to test this on. Then I realised that half of my house is covered in Ikea GORM shelves   and I set to tightening those suckers up. The teeth of the wrench slipped neatly into place, and away I went. This is indeed a Wrench That Fits.

The next aspect to test was pretty easy to do. The texturesd bevel of the pry-bar end made quick work of jars, cans and a variety of "things to pry" that I might have at one time or other thought to use a screw-driver, butter knife on, but NEVER the end of my multi-tool knife blade (oh no, that was snapped off by rabid goblins).

The "outside edges" are all smoothed off, giving a very comfortable grip, all the way down to the pry-bar end, which is not rounded, but smooth. Certainly enough grip to be used as an impromptu kubaton, if the need arose.

The internal edges are crisp, but not rough, and given that this is a titanium tool, I expect they will probably pretty much stay that way. 

Along with my SAR GlobalTool Dead Ringer comb, and my Snowpeak Spork this is the third titanium tool that I have added to my EDC, and I am really pleased with it so far.

Comparing it with my CountyComm Micro Widgy pry bar, it is a little shorter, and given its complement of ten socket options as well as a pry end, is significantly more multifunctional.

That said, I'm not throwing out my Micro Widgy either. Two is One, One is none.

So as not to keep all my eggs in one basket, (and really, two pry bars on one set of keychain tools is a bit excessive, even for me) I have taken to wearing the WTF on my necklace, with a simple split ring through the lanyard hole, where it sits beside my SAR Global Tool MoonGlow and my 500-700BCE pre-Han dynasty Chinese bronze arrowhead that I got whilst visiting my parents in Beijing. The irony of 2500 years between these two pieces is only magnified by the delightful chiming they make as I wear them, especially when being vigorous, or adventuring.
