SPD X-11

The SPD X-11 is PDW's most compact titanium EDC cutting tool, purpose-built around the widely available X-acto No. 11 utility blade. A titanium unibody deploys the blade in four incremental positions via a single button press and retracts flush when stowed. Thinner than a AAA battery and barely longer than your pinky, the X-11 belongs on a keychain, in a survival kit, or in any field kit.

  • Overview
    The Special Projects Division X-11 takes a proven blade standard and builds the most capable minimal platform around it. The No. 11 utility blade has been a fixture in surgical suites, model shops, and precision work for decades. The X-11 puts that proven cutting edge inside a 6AL-4V titanium unibody with four deployment positions, a C3 Super-Luminova button for low-light identification, and a lanyard hole for positive retention. Ships with a dedicated disassembly tool and spare parts for long-term field serviceability.

    Great Product and Service

    I've been using this little EDC for about 8 months now and finally decided to change the blade. Unfortunately, I fumbled the disassembly and lost both springs. Customer service was quick and helpful, mailing me replacement springs. I would recommend the product and company to anybody!

    So close to being perfect

    The SPD X 11 is a great high-quality, minimal EDC cutting tool. I love the fit, finish, and fidget factor. However, the x11 has two shortcomings that make it impractical: first, the slotted screw that holds the thumb slide mechanism together is an odd, atypical flat head screw with rounded corners. A 2.5 mm flat head screwdriver or smaller is the only screwdriver that can be used to unscrew it or tighten it. It would have been more practical to make the slot in the slotted screw go from edge to edge of the screw head, OR just make it a T6 torx screw head. Second, I'm having a hard time finding #11 blades that fit the blade seat in the thumb slide mechanism. Despite the claim that this tool was designed for Xacto #11 blades, I haven't been able to find Xacto 11 blades that fit consistently. It seems that the tolerances between the blade seat and the blade hole in #11 blades are way too tight. I haven't tried several xacto brand and off brand name #11 blades, but none fit as easily as the #11 blade that it came with.

    Smaller than I thought

    Great design and functionality, as others have stated it is smaller than expected. If you thought this would fit in your hand nicely you are mistaken. But also a great tool. Bonus if you forget and leave it in your bag at the airport you can remove the blade and toss it, they’re pretty cheap on the amazons to replace the blade.

    Replacement Blade Question

    @PDW: I am having a difficult time finding #11 replacement blades that fit. The hole into which the locking mechanism (the thing with the springs) is *just* a bit too large to fit the 3 different replacement blades I have tried.

    Is there a specific brand you can recommend so I can change out my now-dull blade?

    Standard X-ACTO No.11 should work perfectly.

Small but
Mighty

The SPD X-11 is a very compact, yet highly capable cutting tool. Barely over 8 grams in weight, smaller in diameter than a AAA battery and about as long as your pinky finger.

Titanium EDC

PDW builds in titanium because it performs where other materials fail. The SPD X-11 is that commitment at its most compact.

image

Advanced, Utility
Design

The X-11 handle is shaped from a single piece of 6AL-4V titanium billet, creating a true unibody cutting tool with no assembled housing. Four preset blade positions and a recessed button deliver reliable, intuitive operation in a footprint smaller than a AAA battery.

Best
Grade

The X-11 is built from 6AL-4V Grade 5 titanium billet and fitted with a C3 Super-Luminova (Strontium Aluminate) cabochon, the brightest photoluminescent grade available. PDW makes no concessions on material quality. The No. 11 utility blade standard was chosen deliberately: globally available, razor sharp, and sourceable anywhere in the world.

A to Z

The X-11 ships in a signed SPD tin presentation box, reusable by design. Compact enough to serve as a fire kit, a sewing tin, or a pocket stash box, it reflects the same attention to detail as the tool itself.

Disassembly
Tool

The X-11 includes a handy small driver that is designed to perfectly fit the small machine screw that holds the locking button parts together. Use this tool to quickly and easily disassemble the locking button to replace the X-acto no.11 blade.

Special
Projects
Division

The Special Projects Division designation isn't given lightly. It marks tools that required PDW to solve problems without precedent — products where standard approaches fell short and new methods had to be developed from the ground up. The X-11 earned it.

FAQ

What blades does the SPD X-11 use?

Standard X-Acto No. 11 utility blades — one of the most widely available cutting blades in the world, found at art supply stores, hardware stores, and online retailers worldwide.

Can I carry the SPD X-11 on a plane?

No. The X-11 has a blade and is subject to TSA and airline restrictions. It must be packed in checked baggage when traveling by air.

How do I change the blade?

The X-11 ships with a dedicated disassembly tool and spare parts. Blade replacement requires disassembly of the unibody handle. Simply unscrew the slotted machine screw with the provided disassembly tool/driver and carefully pull apart the lock button components. Be careful to not lose the small springs. Extra parts are included just in case.

What is C3 Super-Luminova?

C3 Super-Luminova (Strontium Aluminate) is the highest-grade photoluminescent material used in high-end watch dials and tactical equipment. The X-11 button cabochon charges from any light source and glows in complete darkness for low-light identification.

Is the blade replaceable in the field?

Yes. The included disassembly tool and spare parts allow for field blade replacement. Replacement X-acto No. 11 blades are available globally. Check blade compatibility if using clones. Not all clones are the same dimensions as the X-acto brand.
