Big Idea Design x Chaves Bolt action pen Signature Chaves Skull Clip Schmidt P900 refill Two brands you recognise instantly by one detail. With Chaves it’s the skull clip, with Big Idea Design it’s the titanium and the mechanism. This collaboration brings both together in one pen, as a limited edition, in stonewashed or Black DLC. Bolt action means: you push the bolt forward with your thumb, the refill comes out, and it makes a solid mechanical clack. The principle comes from the bolt-action rifle and has caught on in EDC because nothing deploys by accident — the bolt has to be walked through its track before the tip appears. So nothing happens in your pocket that you get to admire on the inside of your trousers afterwards. The body is turned from solid titanium at 10,9 cm overall. Short enough for the notebook in your pouch, long enough that your hand doesn’t cramp while writing. The stonewashed finish absorbs new scratches instead of putting them on display, while the DLC version stays matt and deep black and disappears into a blacked-out setup. The deep carry clip can be reversed, which lefties will appreciate. And sitting on top of it is the Chaves skull clip. About the story behind that skull: “chaves” is Portuguese for “keys”. The skull points to Golgotha, the place of the skull. Out of both came the skeleton key in the brand logo of Ramon Chaves, who started out as a custom maker and whose overbuilt folders are now among the best-known names in the EDC segment. Big Idea Design, in turn, is based in Chattanooga, Tennessee, was founded in 2009 by Chadwick Parker and Joe Huang and broke through on Kickstarter in 2011. Titanium has run through nearly everything they’ve made since, and every pen carries a lifetime warranty. The Base Line is their deliberately accessible series: the same build quality as the flagship models, but instead of the auto-adjusting collet that swallows hundreds of refill formats, it’s set up for the Parker standard. A Schmidt P900 comes fitted from the factory, and because Parker-style is so widespread you can switch to just about anything you’re used to. Ballpoint through gel. Who’s it for? Anyone with a Chaves in their pocket who wants the matching pen. And anyone after a titanium pen that gets written with rather than sitting in a display case.

Replacement Refills for Bolt Action Markers 5 refill cartridges with magnetic caps

The Big Idea Design Bolt Action Marker is essentially a permanent marker – just built the way you’d want it as an EDC tool. No plastic body, no cap that disappears after a week. Instead, you get a solid metal construction with a bolt-action mechanism – that same satisfying “click” you usually only get from high-end EDC pens. Inside, it runs on inserts from retractable Sharpie permanent markers. No proprietary refills, no hassle. When it runs dry, you just swap the insert and keep going. The internal sealing system is what makes this work. It keeps the refill from drying out, even though there’s no traditional cap. Refill changes are tool-free thanks to the magnetic tip. Everything stays in place, nothing rattles around. Add a deep carry clip, and this is something you actually carry – not just leave on your desk. Workshop, warehouse, cardboard, cables, wood, quick marks on the go – this isn’t a marker you lose in a drawer. It’s a refillable tool for people who are done with disposable gear.

Compact trouser pocket fixedMade in USA VersionBlade steel: Nitro V2 Kydex sheaths included (for left or right trouser pocket)Includes a titanium pocket clipMADE IN USA!  The nod to “view” in the name is no coincidence: “Lookout” refers to Lookout Mountain near Chattanooga – a place with perspective. Just like this knife. Designed with one goal in mind: to be a reliable companion. Not a decorative piece, not a shelf queen, but a tool built to be used. Every day. Outdoors. In everyday life. Or wherever a sharp blade is needed.  Now for the best part: this version is Made in the USA. No imports – fully crafted in Big Idea Design’s brand-new workshop in Tennessee. The flat-ground Nitro-V blade is sharp, corrosion-resistant, and made for daily use. The handle, with its screwed-on scales in Micarta, G10, or Ultem, sits solid in the hand, even when wet or dirty. Thanks to its compact size and low weight, you get one of the ultimate pocket-fixed blades here – big enough to handle real work, small enough to stay out of the way in your pocket. Included: two Kydex sheaths – for both left- and right-hand carry – and a sturdy titanium clip.

Big Idea Design x Auxiliary Manufacturing Fixed Blade · Titanium · M390 The Pocket Bowie is no ordinary fixed blade. Michael Jarvis of Auxiliary Manufacturing released a design in 2023 that immediately caught the attention of the EDC world – compact, distinctive, with the unmistakable character of a classic Bowie. For its two-year anniversary, Big Idea Design translated the original into their own language: heavily stonewashed titanium, M390 and their signature Kydex sheath. The result is a fixed blade that actually belongs in your pocket. Titanium Handle. The handle is Grade 5 titanium – light, tough and built to last. Big Idea Design is known for their intense stonewash finish: the knife is tumbled for hours with ceramic stones or abrasive media until both handle and blade have a matte, lightly textured surface. Signs of use barely show – the knife keeps looking good. M390 Blade. M390 is one of the most popular steels in the premium segment. Exceptional edge retention, excellent corrosion resistance, 61 HRC hardness. The 2.8" Bowie blade with clip point is sharp enough for precise work and tough enough for everyday use. With a blade length of 2.8", the Pocket Bowie is fully legal to carry in Germany – no pocket knife, but just as practical. Kydex Sheath with Deep Carry Clip. Two Kydex sheaths are included – one for left, one for right carry. The deep carry titanium clip makes sure the knife disappears deep in the pocket and stays exactly where it belongs. A lanyard hole rounds out the setup. Big Idea Design – Titanium is their language. Big Idea Design is based in Chattanooga, Tennessee, and has been making premium EDC gear from titanium since 2009. Starting with pens, now known for knives, tools and pry bars – always with the same goal: carry as little as possible, have everything you need. The Pocket Bowie fits that philosophy perfectly. An anniversary with substance. This version is not a limited special edition for the sake of it. It's the logical evolution of a design that impressed from day one – now with the materials and craftsmanship it deserves. For everyone looking for a premium EDC fixed blade that doesn't stand out, but is always there when you need it. Compact. Consistent. Always there.

Big Idea x ASW Fountain Pen – handcrafted silver with character Handwriting is always personal – and a fountain pen makes it just a little more special. The Big Idea x ASW Fountain Pen is built exactly around that idea: a classic writing experience combined with honest materials and true craftsmanship. The foundation of this pen is solid brass, giving it a pleasant weight and calm, well-balanced feel in the hand. What makes this version truly special is the finish: each pen is hand silver-plated at the Altonaer Silberwerkstatt. No industrial coating, no shortcuts – just a genuine layer of silver, carefully applied by hand. Afterward, every pen receives a hand-rubbed finish and a subtle antique silver tint in the upper section. The result is a beautiful contrast between light and dark tones and a slightly aged look that practically invites you to pick it up. The surface has real depth and character, developing a natural patina over time that becomes uniquely yours – much like your own handwriting. This is not a sterile object, but a pen that evolves with use. Despite its premium materials, the Big Idea x ASW Fountain Pen remains a true EDC writing tool. Compact enough to slip into a pocket, yet long enough when posted to allow for comfortable, relaxed writing. Inside, a Bock Extra Fine nib delivers clean ink flow and precise lines, whether you’re jotting down quick notes or writing longer passages. Included is a Kaweco mini converter, allowing you to use both international standard cartridges and bottled inks. Perfect for anyone who enjoys experimenting with different inks or prefers something a bit more special. When using iron gall ink, occasional rinsing with clean water is recommended to keep the nib performing flawlessly over time.

Sometimes it’s the little things that make everyday life easier – and the TPT Slide by Big Idea Design is exactly that. A compact titanium tool that disappears in your pocket, but is always there when you need it: opening packages, tightening a screw, popping a bottle cap or doing a bit of prying. And because we believe that a multitool should also have character, we teamed up with Big Idea Design to create a Knife Lounge Exclusive version: a professionally applied Cerakote finish from the USA in deep green, paired with a mustard-yellow lanyard inspired by our logo – our signature touch for your pocket. What the TPT Slide can do (and it’s a lot): One-handed slide mechanism with replaceable blade Mini prybar for all kinds of small tasks Bottle opener Two screwdrivers (flat & wide) 6 mm hex opening for bits Ruler & measurement scale Scraper for adhesive residues Universal wrench (15 sizes) Keyring/lanyard hole All made from Grade 5 titanium: lightweight, strong, and built to last a lifetime. Why you’ll love it The TPT Slide isn’t a bulky multitool – it’s a smart everyday companion that you hardly notice until you need it. And when that moment comes, it saves the day. In this Knife Lounge Edition, it also carries a piece of our community DNA: tough, practical, and just a little nerdy – just like us.

If the Big Idea Lookout had a growth spurt, this is exactly what it would look like – a true evolution signal (gotta catch ’em all). The Signal is the second fixed blade to come out of Big Idea’s US production, and it’s an absolute powerhouse. Crafted from Nitro V steel with a blade length of 8.2 cm, it slices smoothly through firewood out in the wild – or, for the desk warriors among us, through the hundredth pack of printer paper. For the handle, you can choose between a bold and mood-boosting black G10 or a natural micarta that develops a beautiful patina over time. As always with Big Idea’s fixed blades, it comes with two Kydex sheaths and a titanium clip.
