Coinax EDC Tool on Kickstarter: Titanium and Damascus Steel in a Coin-Sized Carry Format

Every tool you carry costs pocket space. The Coinax EDC tool on Kickstarter changes that equation: at 25mm × 8mm and 14.7g, it is smaller than an Apple AirTag, fitting in the fifth pocket of a pair of jeans, with a titanium body, Damascus steel cutter and bottle opener, and a flathead screwdriver that deploy from opposite sides of a coin-sized frame.

The campaign has raised $2,272 from 33 backers against a $1,531 goal, with 21 days remaining. Gear Patrol featured the Coinax at launch as a standout coin-sized carry solution. Coinax Tools Limited was founded by outdoor enthusiasts, engineers, and industrial designers with prototyping and manufacturing partnerships in place before launch. The base stainless steel model starts at $35; the Titanium and Damascus Steel configuration is $49.

Quick Verdict

Who Is It For?

EDC enthusiasts who already carry a full keychain and want cutting and bottle-opening capability without adding meaningful weight or bulk. Also suited to minimalist carry users who want one multi-function coin knife that disappears into any pocket and requires no deliberate decision to bring it.

Main Strengths

• At 25mm × 8mm and 14.7g, it fits in a jeans fifth pocket and clears the AirTag size threshold, making it exceptionally compact for a titanium multi-tool.

• Titanium body with Damascus steel cutter and bottle opener: premium EDC materials with genuine performance. Each insert carries its own forged pattern.

• Three functions from one coin-sized body: cutter, bottle opener, and flathead screwdriver, with edge passivation treatment that prevents skin cuts during deployment and handling.

• Magnetic attachment system enables desk, refrigerator, or workshop surface mounting between uses, with a snap-and-hold feel designed for repeated daily access.

• Compatible with keychains, backpacks, and AirTag-style holders: multiple carry formats without adding accessories.

  
  

Main Limitations

• First Kickstarter campaign from a first-time creator with no previous delivery history on the platform.

• At this size, functions are limited to light-duty tasks: package cutting, bottle opening, and basic screwdriving. Not a replacement for a full-size multi-tool.

• The base $35 tier ships in stainless steel. The full titanium and Damascus configuration requires the $49 One Pack, not a $35 upgrade path.

  
  

Is the Coinax EDC Tool Worth Backing?

The Coinax EDC tool on Kickstarter delivers titanium and Damascus steel materials in a quarter sized knife format that has no direct equivalent at this price. The manufacturing setup was confirmed before the campaign opened. At $35 for the base and $49 for the full titanium and Damascus configuration, the Kickstarter pricing sits well below what comparable material quality typically commands in the EDC market.

What Is the Coinax EDC Tool?

The Coinax is a three-function coin-sized EDC multi-tool: cutter, bottle opener, and flathead screwdriver, machined to fit within the footprint of a standard coin. At a size category where most tools sacrifice material quality or function count to hit the size target, the Coinax EDC tool on Kickstarter brings titanium and Damascus steel to a 25mm × 8mm frame.

The body is available in stainless steel at the base price, with a titanium shell upgrade that cuts weight without sacrificing strength. Both inserts (the cutter and the bottle opener) deploy from opposite sides via nail-nick slots, and each is available in Damascus steel, a forged layered blade material where every piece carries its own visual pattern. Edge passivation on the cutter reduces the risk of accidental contact during handling. The magnetic system on the back holds the Coinax to any ferrous surface between uses. A lanyard attachment point connects to keychains, backpack pulls, or backpack loops, and the 25mm × 8mm form factor fits AirTag-style holders directly.

Coinax Tools Limited was founded by outdoor enthusiasts, engineers, and industrial designers with a stated philosophy of material reduction and CNC precision. Prototyping is complete and manufacturing partners are secured before the campaign launch. The brand's first Kickstarter project.

What Problem Does the Coinax EDC Tool Solve?

The everyday carry tradeoff is real. A multi-tool adds capability but also adds bulk, and most people leave theirs at home because the weight and pocket space penalty is too high for daily use. The tools small enough to always carry, such as key-sized cards and split-ring blades, tend to compromise on material quality or limit functions to make the size constraint work.

The Coinax approaches this from the material side rather than the size side. By starting with a coin-sized footprint and working backward through CNC precision machining, it preserves three genuine functions in a body smaller than an AirTag. The titanium body and Damascus steel inserts carry the same material credentials found in premium quarter sized knives and high-end EDC blades at significantly higher price points. The coin knife keychain carry format means it adds to an existing keychain without changing the profile of what is already in the pocket.

For daily carry, the result is a tool that costs no real pocket space. That is the entire point of the form factor: a tool small enough to stop being a decision.

Coinax EDC Tool Key Features and Specs: Materials, Functions, and Carry System

Titanium Body and Damascus Steel Inserts: Premium EDC Materials in a Coin Footprint

The Titanium and Damascus configuration is what places the Coinax at the premium end of the coin cutter and quarter sized knife category. The titanium shell offers a strength-to-weight ratio that stainless steel cannot match at this scale, with natural corrosion resistance and a tactile quality the EDC community specifically values. At 14.7g total, the weight difference between the stainless base and the titanium upgrade is measurable.

The inserts are forged through a layered construction process that produces a distinctive flowing grain pattern. Each piece carries its own unique pattern. The forged layered steel combines hardness and flexibility, providing reliable cutting performance alongside the visual character that distinguishes it from standard blade steel. The bottle opener uses the same forging process.

Three Functions in 25mm: Cutter, Bottle Opener, and Flathead Screwdriver

The cutter deploys from one side of the body via a nail-nick slot and handles package opening, tape cutting, and light material work. Edge passivation treatment reduces the risk of skin cuts during handling without compromising cutting performance on intended tasks.

The bottle opener deploys from the opposite side, also via nail-nick. The flathead screwdriver occupies the tip of one of the inserts and handles standard slotted fasteners. Three distinct functions, two deployable inserts, zero wasted form factor.

Magnetic Attachment, Keychain, and AirTag Compatibility: Carry Your Way

The magnetic system on the back of the Coinax secures it to any ferrous metal surface: refrigerator door, toolbox, workshop surface, car dashboard. The snap feel is designed to be satisfying and repeatable for daily use. Between uses, it stays visible and accessible without a dedicated pocket or case.

The lanyard attachment point connects directly to a keychain, carabiner, or backpack zipper pull. The 25mm × 8mm form factor fits standard AirTag-style holders without modification. Carry options include pocket carry, coin knife keychain attachment, backpack attachment, and magnetic surface mounting: a range that most tools in this category do not offer from a single unit.

Coinax EDC Tool Price on Kickstarter

The Coinax EDC tool on Kickstarter starts at $35 for a single unit in stainless steel. From there, two material upgrades are available: a $9 titanium shell replaces the body, and a $9 Damascus steel upgrade replaces both the cutter and bottle opener inserts. Buying both upgrades on the base unit brings the total to $53.

The smarter entry is the $49 One Pack, which bundles both upgrades together (titanium body and Damascus steel inserts) and saves $4 against the individual upgrade path. For most backers, the $49 One Pack is the right tier: stainless steel is functional, but the titanium shell removes meaningful weight at this scale, and the Damascus inserts are what give the Coinax its visual identity in the quarter sized knife market.

Add-ons include a rotatable lanyard ($5), silicone case and metal keychain ($7), leather case with brass key ring ($9), and titanium alloy universal buckle with leather case and titanium keychain ($26). All tiers ship worldwide with September 2026 estimated delivery.

Should You Back the Coinax EDC Tool on Kickstarter?

The Coinax does not exist because someone thought a coin-shaped blade would be cute. It exists because pocket space has a real cost, and most EDC tools still treat that cost as someone else's problem.

Titanium body, forged Damascus inserts, three daily functions, and a magnetic carry system at 14.7g and $49: that specification does not have a direct competitor in the coin-sized carry category at this price. Gear Patrol covered it at launch as a standout solution for compact carry.

Coinax Tools completed prototyping and secured manufacturing partnerships before the campaign launched. This is their first Kickstarter with no previous delivery history — that is the honest caveat. The $49 One Pack is the tier to back: it covers both the titanium body and the Damascus inserts, and those two materials are what separate this from every other quarter-sized carry tool on the market. The Coinax EDC tool is currently funding on Kickstarter, shipping September 2026.
