Black Triangle posted a sneak peek of an upcoming addition to their Midnight Creeper line. The new MK4 features a flared pommel with symmetrical finger choils designed to give the user immediate feedback on grip position. It is dimensionally similar to the MK1 which is an excellent tool.

The EDC Toll Roll: Prestacyle T-Handle Ratchet

The EDC Tool Roll is a feature on Jerking the Trigger in which we profile various everyday carry worthy tools. The tools shown aren’t multi-tools but rather real tools, that by virtue of their compact size, light weight, usefulness, or unique functionality, can find a place in any range kit, emergency kit, or everyday carry bag.

Feel free to comment on the tools that you carry so we can all learn! The discussion on these posts has been very valuable so far.

The Prestacycle T-Handle Ratchet, like the previously reviewed Topeak Ratchet Rocket, is another tool you are more likely to find in a bike shop than a hardware store. This ratchet boasts an incredible combination of size, functionality, and a cool trick that makes it not just one of my favorite ratchets for EDC but one I reach for no matter the task.

Shown with Knipex Cobra Pliers (87-100) for scale.

The T-Handle Ratchet is available by itself or in kit form. I ordered mine with just the tool itself since I have a ton of bits and socket adapters already. However, it is available with a selection of bicycle-centric bits and a carrying case if you choose.

The T-Handle Ratchet looks similar to the previously reviewed Topeak Ratchet Rocket DX Lite in that it accepts standard 1/4″ shank bits, has a typical ratchet end, and the very handy, non-ratcheting, inline bit holder end. However, it is slightly larger (about 4.5″ long and 3 ounces) than the Topeak tool, making it easier to use. It also comes with an extension that knows one very cool trick.

The extension can be inserted into the ratchet end of the tool, as you would expect, to extend the reach of the ratchet. However, if the user lines up a witness mark on the extension with a witness mark on the ratchet end of the tool, the extension can pass through the ratchet end about halfway creating a very useable T-handle driver. This mechanism is not only very cool… it makes the T-Handle Ratchet a versatile multi-tasker for any EDC Tool Roll.

The quality of the tool is excellent. I would put it on par with VIM Tools Ratchets from previous reviews. It features a fine ratcheting mechanism that is reversible and has a thumbwheel. The bit holders have appropriate tension and the finishes seem to be very durable.

The tool and kit do not come with a hex shank to socket adapter. It is worth adding one on your own because makes a fine socket wrench and nut driver. I purchase them from iFixit.

Where to Buy:

You stand a good chance of finding this tool locally in your bike shop though it isn’t as widely available as some bicycle tool lines. If you can’t support your local spot, Amazon has it: Prestacycle T-Handle Ratchet

The Gatorz x Ronin Collection

Gatorz Eyewear is excited to announce the Gatorz x Ronin Collection. The Gatorz x Ronin Collection is a collaboration between Gatorz Eyewear and former U.S. Army Green Beret Tu Lam of Ronin Tactics. This collection is made to the exceedingly high standards that all Gatorz Eyewear has come to represent to the Special Operations community, including meeting American National Standards Institute (ANSI) Z87+ rating and offering some features of MILSPEC Ballistic protection standards.

“A journey of a thousand miles begins with a single step.”

Lao Tzu

Tu Lam. a former U.S. Army Green Beret and founder of Ronin Tactics, fled communist Vietnam in 1979. The Lam Family escaped on an overloaded boat and eventually reached the safety of the United States as refugees.

Tu was raised by his Step-Father, an Army Special Forces veteran, and drew inspiration to eventually serve as a member of the Army Special Operations Community. For over 23 years, Tu traveled across 27 different countries and a number of war zones as a career special operator.  During that time, he fought alongside and within the most elite units of the United States Military.

As the Founder and CEO of Ronin Tactics, Inc., Tu now develops innovative tactical equipment and teaches a range of Close Quarters Battle instruction for our military, Law Enforcement, and responsible armed citizens. Tu co-hosted three seasons of the History Channel’s “Knife or Death” and was developed into a playable character “Ronin” on the popular video game “Call of Duty.” Gatorz Eyewear is honored to be working with him.

Sam Havelock, The Chief Brand Officer of Gatorz eyewear and himself a former Navy SEAL, had this to say,

 “We thought the collaboration with Tu Lam, whose background includes having to flee persecution from war-torn Vietnam especially fitting given the current state of affairs in Afghanistan. Gatorz Corporation is extremely committed to the Special Operations Community and closely identifies with the Mission of the Army Special Forces Community to Free The Oppressed  (De Oppresso Liber). 

The Ronin Edition collaboration with Tu Lam is an example of our willingness to partner with diverse members of our Gatorz Tribe who live a Mission-Driven life. Tu Lam’s personal history of service with the Special Operations Community coupled with his family’s legacy of relationships across Army Special Forces perfectly embodies our joint belief in the power of relationships and humans to overcome all obstacles during their Life’s Most Important Missions.”

Dark Angel Medical Deploys HEDR 2.0 Vehicle IFAK

Dark Angel Medical is happy to announce they’ve upgraded the original HEDR  (Headrest Emergency Deployment Rig) Trauma Kit. The updated HEDR 2.0 trauma kits are now better designed to withstand the shock of offroading and backroad travel.

“Mountains are not fair or unfair, they are just dangerous.”

Reinhold Messner

The NHTSA and CDC advise 2 million + people are injured every year in a vehicle accident. Thousands more are killed (34,000 in 2017 and 36,000 in 2019, for example). This makes traffic-related fatalities the third most common non-health-related cause of death in the United States.

Knowing these numbers, why wouldn’t you have something in your vehicle to deal with trauma? Why avoid life’s adventures just because they’re riskier than staying home? With this upgrade, you can be as prepared off-road as you are on

We road-tested the HEDR in the mountains of our Colorado HQ and decided it was time for an upgrade. There’s a new retention strap to keep it securely mounted to the headrest. Additional straps inside the kit to keep individual contents firmly in place and accessible if an emergency interrupts your day  – saving you precious seconds if you need to access them.

The HEDR is available in Black, Coyote Tan, or Wolf Grey.

Here’s what the full HEDR 2.0 kit contains:

  •   1 x Hemostatic Gauze (QuikClot Bleeding Control Dressing or ChitoGauze)
  •   1 x Pair Nitrile Gloves
  •   1 x Mini Compression Bandage
  •   1 x HALO Seals
  •   1 x Compressed Gauze
  •   1 x Eye Shield, Polycarbonate
  •   1 x Mylar Blanket
  •   1 x NPA
  •   1 x CAT or SOFTT-W TQ with room for 2 more tourniquets
  •   1 x Full-Size Shears 

Note: Can be upgraded to ARS, HALO Vent or a combo of both

Complete Kit Weight: 3 lb

Complete Kit Dimensions: 6.5” Tall x 11.5” Wide x 1.5” Thick

HEDR Panel Weight: 1 lb

HEDR Panel Dimensions: 6.5” Tall x 11.5” Wide x 0.75” Thick

The HEDR deployment rig (pouch only) can be purchased separately, as can individual tourniquet holders.

Simplicity under stress.

Fourfold Improvement in WNDSN Telemeter Accuracy

BERLIN, 2021-10-14 – WNDSN Applied Sciences Lab presents a significant update to their main product, a new sighting scale that improves the Telemeter accuracy by 400%. The WNDSN Telemeter is a low-tech, naked-eye distance measuring instrument based on comparing the triangle between our eye and a scale with the triangle between our eye and the object in question.

“It’s not what you look at that matters, it’s what you see.” –Henry David Thoreau

In response and in collaboration with users who report problems in sighting accuracy due to the fixed distance between eye and scale that the Telemeter operation requires, WNDSN has developed a new sighting scale inspired by surveyor’s instruments with scale marks in E shape.

For the new sighting scale blocks instead of lines are used as scale marks, filling every other pair of lines with a solid color. This change increases the width of the smallest element which the user can visually discern from 0.25 mm to 1 mm — yielding a fourfold increase in legibility.

To introduce this improved scale, it has been added to the Night Ops Telemeter, which is already optimized for enhanced visibility in the dark. A bestseller ever since its release, the Night Ops Telemeter is a going-back-to-the-roots, bare bones Telemeter in clear acrylic.

The WNDSN Telemeter upgrade is designed to help people with short-sightedness or other visual impairment but it also increases accuracy for users who have no issues sighting with the original scale.

Made in Germany.

WNDSN’s Applied Science Lab, based in Berlin, develops and manufactures that which can’t be improvised; measurement, navigation, and surveying instruments informed by the motto “Ex Mensura, Scientia” — knowledge from measurement.

WNDSN produces archival quality products that are designed with intent by combining techniques proven over centuries; arcane science meets cutting edge contemporary methods, resulting in iconic, timeless, high-utility designs.

In addition to custom-built instruments and tools, metrology & illumination solutions, WNDSN creates expedition mementos and morale patches to celebrate cross-disciplinary exploration in the spirit of the Renaissance. WNDSN morale patches are acutely designed — no line is left to randomness, no element is mere filler. They serve as infographics, how-tos for the WNDSN tools, magic sigils, as well as functional markers.
