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.

Review: WELmade Knives Skylark

The Skylark series of knives from WELmade Knives consists of a single design in multiple finish options. It’s design is both practical and radical… brutish and refined. It’s a very visual knife that is aimed squarely at the everyday carry (EDC) market and comes with everything you need to add it to your EDC right out of the box.


The Skylark is crafted for WELmade knives by Dauntless MFG. If you are familiar with Dauntless MFG, you’ll know they bring a custom level of fit and finish to both the knives and sheaths that they craft.

It features a 3.24″ long blade with a modified tanto/recurve shape that is ground from 154-CPM steel. This full-tang construction knife is 7″ long overall and weighs 5.5 ounces with the included kydex sheath. It is available with multiple handle scale options including the black G-10 over white G-10 liners on my example. The handle screws are blue anodized titanium.

Observations from Use

The Skylark is a striking knife – not just in the design but also in the details. The shape is eye-catching and very unique. The stone-washed blade finish looks great and the handle treatment brings to mind a tuxedo. The pop of color from the screws is subtle depending on the light but it makes you take a second look when they catch the sun. I just like looking at it and I have told others that I am not cool or classy enough to carry a knife like this.

Thankfully, WELmade Knives intends for you to do more than look at this knife. The blade shape, while unconventional, is very useful. The recurve section catches things like twine and cuts it aggressively. The leading edge has a slight amount of belly and reminds me of a chef’s knife or a kiridashi in how it orients in the hand and lays on a cutting board. The high flat grind makes this knife surprisingly “slicey” and the swedge grind gives a very strong, useful, and acute point. I would probably prefer a flat section of edge to the small section of recurve but I can’t deny that this blade shape wants to work.

The handle on this knife looked small to me in pictures but looks are deceiving. WELmade Knives gave us some nice, thick scales. It is actually quite hand-filling while still remaining compact for carry. The handles are mostly round but with flats that prevent the knife from turning in the hand. The finger choil behind the well-rounded guard is somewhat compact but works well for my average-sized hands. It might be a little cramped for sausage fingers. I easily fit all 4 fingers on the handle and find it to be comfortable for edge-out and edge-in grips.

The sheath that is included with the Skylark is excellent. It is a fold-over, kydex sheath that is very compact. It is machined to fit the contours of the knife perfectly and the included Discreet Carry Concepts clip makes it very easy to clip on and go. It carries well in a pocket or on your belt line. Dauntless MFG is well-known for their sheaths and sheaths like this are the reason why that is. It’s very well designed.

This offset rivet in the sheath is one of the keys to how well the Skylark carries.

There are a lot of thoughtful touches on this knife that really only come out when you spend time with it. It has a nifty shallow thumb rest on the top that falls naturally and comfortably under the thumb. This ramp provides just a little more control for cuts in both directions. I also appreciate how the shape of the handle sort of grips the first 3 fingers with a broad, shallow finger groove which also works in concert with the thumb ramp to provide more purchase for both push and pull cuts. The tapered shape of the handle lets the user orient the edge to a flat surface easily while providing clearance for the knuckles. Finally, the sheath itself has a clever offset rivet that makes it so the clip can ride more vertically and closer to the centerline. This is extremely clever and really improves how the knife carries.

Nothing is perfect. As good as this knife is, it could be even better. It works really well in a pinch grip so it would be nice if the scales were relieved just a little bit to better support this useful grip. The edges of the sheath were a little sharp around the opening and these edges can be pushed into your side when the knife is out of the sheath. I trimmed the sharp parts easily but it would be nice if that was already done.

Wrap Up

This is a visually striking knife that is easy to carry and offers a ton of utility in a small amount of space. The quality and design touches exude pure class but the materials and shape beg for work. If you are looking for a unique fixed blade for EDC that is both gentlemanly and rugged, the WELmade Knives Skylark has to be on your radar.

Introducing the WNDSN Explorer’s Notebook

BERLIN, 2021-09-15 – WNDSN Applied Sciences Lab is excited to announce their first adventures into stationery, with the WNDSN Explorer’s Notebook.

“Keep a notebook. Travel with it, eat with it, sleep with it. Slap into it every stray thought that flutters up into your brain. Cheap paper is less perishable than gray matter. And lead pencil markings endure longer than memory.” –Jack London

Calculations only become real when written down, and for years Telemeter and Quadrant users have had to go without a dedicated WNDSN notebook to capture their most necessary computations.

The WNDSN Explorer’s Notebook is a one-of-a-kind addition to the stationery marketspace. This pocket notebook is designed for easy portability, durability, and pleasure of writing, and comes with several unique features.

The user will first appreciate the 40 pages of dot grid paper, designed for ease of writing, drawing, and calculation notation. However, it comes with a twist. The right page maintains a conventional square grid, while the left page is an isometric grid. Held right side up, the grid lines flow from one page to another; the user’s writing will be seamless. By turning the notebook 90 degrees the isometric grid is ready for 3D drawings.

The team at WNDSN are fountain pen aficionados, and the sensual experience of writing was first and foremost on their mind. The Explorer’s notebook is made with Swedish Munken Pure 120g/m² (32 lb) paper. Munken Pure is cradle-to-cradle certified, from sustainably managed forests and will take even the inkiest fountain pen without bleed through.

The spirit of experimental exploration is always at the heart of WNDSN products and no product would be complete without aids to ensure that the explorer has accurate mathematical results. In the back of the notebook the user will find a compendium of useful scientific guides and 18 conversion nomograms for all of their exploratory needs.

The advantage of using nomograms, a WNDSN specialty, is that unlike tables they work both ways, back and forth and in a graphical, at-a-glance, intuitive fashion.

The guides include:

  • Trigonometry: Definition of SOHCAHTOA and an explanation of the Law of Sines.
  • A Sine Quadrant with short instructions for graphical sine, cosine, and tangent computation.
  • 18 unit conversion nomograms for angle, speed, temperature, mass, volume, and length.
  • The WNDSN moon clock, a visual aid in determining time from moon phase and observed lunar shape and altitude.

No detail is left to chance, and as a finale, the cover is as useful as it is beautiful. Featuring Fedrigoni Sirio Black 290g/m² (107 lb) stock, the front cover is embossed with the WNDSN Polaris logo, a favorite amongst patch aficionados. The back cover features a 10-degree Telemeter, realized in white screen-printing complete with instructions to attach a paperclip with some string to the back of the notebook, for a fully working Telemeter.

WNDSN is excited with this first foray into stationery and note taking products, with more to come. With the WNDSN Explorer’s Notebook, WNDSN delivers an exclusive notebook with a unique and exemplary paper experience. And as added value, the scientific compendium, Sine Quadrant, and Telemeter will be useful to all explorers who value or rely on analog tools and precision when out in the field.
