The blade uses S30V stainless steel which, again, is a material perfectly suited to the rigors of Every Day Carry. And of course it's UK Friendly Carry (non-locking and under 7.6cm blade length) so take it with you in pocket, pouch or pack.

“Fantastic knife! Very lightweight, the scales are beautiful. S30V is still a great steel. A wonderful addition to my ever expanding UKPK collection.”

“Imagine the UKPK but as more of a statement piece than a tool. This is it. If you're looking for the most practical and functional version of the UKPK the G10 scales is better in terms of grip and texture. But in terms of appearance and aesthetics. Wow. Just wow. This is a beauty. It catches the light in wonderful ways no matter where you put it and looks elegant when holding. It's more smooth and less grippy than you might be used to but it works brilliantly with a suit or as a gentleman's pocket knife in a way the G10 just doesn't. It's a really stunning version of the knife and if your collection is missing that knife you can wear for more formal events this could be it. Or if you're like me and just love the UKPK model this is probably also perfect for you. All in all exactly the same as a regular UKPK in terms of functionality, arguably slightly worse than G10. But incredible in looks and really one of a kind in your collection.”

“The Spyderco UKPK Fat Carbon Dark Matter Heinnie Exclusive, isn’t just a pocket knife; it is a definitive example of how to elevate a utilitarian staple into a functional piece of art. As a UK-friendly, non-locking folder, it manages to balance strict legal compliance with high-end collector appeal. Aesthetics: The "Dark Matter" Factor The star of the show is undoubtedly the Fat Carbon Dark Matter scales. Unlike standard G10 or FRN, this material has a deep, topographical texture that catches the light in a way that feels premium but not flashy. Unique Pattern: No two knives look identical, giving it a semi-custom feel. Ergonomics and Portability The UKPK (UK Penknife) has always been celebrated for its ergonomics, and this version is no different. The Finger Choil: The deep 50/50 choil is a stroke of genius. It provides a massive amount of control for fine tasks and acts as a secondary safety feature; if the blade were to close during use, your index finger prevents it from hitting the edge. Weight: Despite the upgraded materials, it remains incredibly lightweight and disappears in the pocket. The Clip: Spyderco’s wire clip is the gold standard for deep-carry—discreet, sturdy, and won't chew up your trousers. Blade Performance The drop-point blade profile is a workhorse. Full Flat Grind (FFG): This makes the UKPK an absolute slicing machine. Whether you’re opening packages or prepping an apple, the geometry is optimized for effortless cutting using CPM S30v Deployment: The trademark "Spydie Hole" allows for easy one-handed opening (even with gloves), and the detent—the "half-stop" and "full-open" positions—is snappy and reassuringly firm”

“The UKPK is for me the ultimate UK friendly pocket knife. It works well for slicing and fine work with the tip, is extremely easy to deploy and close one handed, and the quality of the blade steel is second to none. I own and have owned many versions of this knife going all the way back to the original. This forged carbon fibre edition is hands down my favourite to look at, but beyond the amazing appearance of the scales, it has a lot to offer in practical terms. It's extremely durable for its weight when compared to metal scales, though is still heavier than the FRN lightweight version, not least because this uses the 4 pin scale design with a full steel back spacer / spring. Grip is surprisingly good when dry, but not so good when wet, so for "all weather" use I would definitely suggest one of the FRN or G10 variants. For casual day to day use though, I would highly recommend it.”
