EDC and stationery have been moving closer together for years. Pens became precision objects. Rulers became desk jewelry. Pocket tools started borrowing the language of industrial design, while analog work tools picked up the portability and finish standards of everyday carry. Somewhere in that overlap, products began chasing a sharper balance between usefulness and desire.
UnioArc feels tailored for that exact overlap. It carries the visual language of titanium EDC, but its purpose lives firmly in the world of measurement, drawing, and layout. That combination gives it an immediate hook. It speaks to the person who keeps a notebook close, notices edge quality, values compact gear, and wants a tool that can move from workbench to sketchbook to shirt pocket without feeling out of place.

Seven measurement and drawing functions collapse into a single folding titanium ruler. Closed, it measures 145mm, roughly smartphone length. One motion releases the magnetic lock, the sleeve joint clicks straight, and it extends to 295mm for full A4 coverage. No sliding mechanisms. No multi-step deployment. The transformation happens edge to edge, from zero to full length in a single click. Three scales cover metric, imperial, and a dedicated millimeter track. All markings are laser-engraved into the titanium surface, which means they will never fade, peel, or rub off. The zero point starts right at the tip, eliminating offset math when measuring depth or inserting the edge into tight spaces.
A 0.5mm recessed groove runs along the bottom edge. It catches a pen tip, holds it stable, and lets you mark immediately after measuring. That same groove improves grip when you’re holding the ruler at an angle or cutting against it. The flat middle edge guides craft knife blades flush against the surface for clean cuts without wobble. The top edge carries a 25-degree bevel to reduce glare and improve readability under direct light. Three edge profiles, three distinct jobs, one continuous form. This kind of multi-layer thinking shows up throughout the design, where individual features earn their place by doing multiple things well instead of one thing adequately.
Precision compass holes span 140mm in 10mm increments. Insert one pen through a hole near the pivot (the sleeve joint), insert another at the desired radius, and draw smooth circles from 10mm to 140mm diameter. No center puncture. No damaged paper or leather. Swap the stylus pen for a craft knife and you can cut perfect circles in paper, thin materials, or vinyl without leaving a center mark. For woodworkers and leather crafters, this solves a persistent workflow annoyance. A full 180-degree protractor sits engraved at 5-degree increments. Need to mark 35 degrees? 55 degrees? Read it directly, no interpolation required. A 90-degree quick-check corner handles faster right-angle verification. A small arrow indicator simplifies complementary angle reading: subtract the arrow-aligned angle from 180 degrees and you have the answer without rotating the tool or doing mental math.
Fold the ruler to 90 degrees, align the reference line with your scale, and set any spacing you want for parallel lines. The arms lock into a true right angle with no wobble or drift as you move across the page. For architectural sketches, textile patterns, or technical drawings, this turns a multi-tool task into a single-ruler operation. The locking mechanism holds firm enough for consistent spacing across long runs. The same two arms that handle linear measurement also slide apart while staying parallel, clamping around boards, straps, or stock to give direct thickness readings. It functions like a simplified caliper without requiring a separate tool. In workshops or on job sites where you need quick material checks, this compresses another measurement step into the same instrument you’re already holding.
No screws hold the sleeve joint together. No washers. Nothing to tighten or maintain. Resistance comes from precision fit between machined titanium surfaces. The two arms slide into each other and lock at 180 degrees with zero gap, zero step, zero play. That interlocking geometry prevents the common folding ruler problem where pen tips drop into gaps or lines skip at the hinge. The transition from one arm to the next reads as seamless. This is critical because any interruption in the edge breaks the flow when you’re drawing continuous lines or cutting long paths. TiBang solved it by making the joint itself part of the measurement surface instead of treating it as a hinge that happens to sit between two rulers.
Grade 5 Titanium throughout, CNC-machined from solid stock rather than stamped or cast. That process ensures consistent dimensional accuracy across every unit and allows for fine detail work in the compass holes, protractor markings, and edge profiles. Sandblasted titanium gives a raw, matte appearance that develops micro-patina over time. PVD Black applies a deep black coating with increased surface hardness for a technical, permanent look. Both finishes share identical machining tolerances and functional geometry. Weight sits at 66.5 grams, just over two ounces. Light enough to carry all day without noticing, heavy enough to feel substantial when you pick it up. The 5mm thickness keeps it shirt-pocket slim, fits inside notebook sleeves, slides into small tool rolls. Fold it shut and magnets snap the arms together with a tactile click. No rubber bands. No retention clips. It stays closed in your pocket and opens when you want it to.
Architects, product designers, woodworkers, leather crafters, engineers, and EDC enthusiasts will recognize the workflow this tool targets. Anyone who moves between sketching, prototyping, and layout work carries some version of this measurement kit already. UnioArc compresses that kit into a single pocketable object, which is exactly the kind of consolidation that makes sense for people who work across locations or keep minimal setups. TiBang has two previous Kickstarter campaigns behind them, both shipped with 100% fulfillment and zero missed deliveries. Mass production and backer surveys are scheduled for May and June 2026, with quality inspection and packaging slated for July and August 2026. The timeline accounts for buffer periods around international shipping and customs clearance, which suggests they’ve learned from previous campaigns how to build realistic delivery windows.
UnioArc is live on Kickstarter with a Launch Day pricing of approximately $55 USD (42% off MSRP of $95) and Super Early Bird pricing climbing to $60. The ruler works standalone, but optional add-ons include a leather sheath in two colors for $12, a PVD Black finish upgrade for $15, and a Pocket Titanium Everlasting Mini Pen for $9. Shipping begins in July and August 2026 following quality inspection. All reward tiers include free worldwide shipping with no additional fees. TiBang manufactures, ships globally, and communicates throughout the process.
