Silver meets Steampunk
The Bastard Knives Arronax Slipjoint has been silver-plated by hand in our Altonaer Silberwerkstatt.
The result is not a sterile high gloss, but a vivid finish with intentionally darkened areas –
an effect that highlights every contour and gives the knife an almost antique depth.
This interplay of light and shadow lends the Arronax a nearly historical aura.
Developed by Bastard Knives in collaboration with the “Mad Professor” Stefan Steigerwald,
the Arronax is a homage to Jules Verne’s 20,000 Leagues Under the Sea. The Verne vibe runs through every detail:
playful Art Deco elements meet clear, industrial-inspired lines – now emphasized even more by the silver plating.
This Version
Brass handle scales with a satin-finished D2 blade, silver-plated in Hamburg.
The patina accentuates the milled holes and structured recesses, highlighting the retro-futuristic look.
Surface Notes
Patina intended: The darker areas are part of the design and deliberately created by hand.
Care: Silver may naturally darken over time. If needed, gently refresh with a soft silver polishing cloth – avoid aggressive cleaners.
Handmade character: Minor variations in tone and shading are normal and intentional.
Clipoint or Persian?
The Xerxes is definitely not a knife for those who like to stay in the middle lane. With its proportions of roughly two-thirds handle to one-third blade, it sits solid and secure in the hand – even with glove size nine. Designer Matteo Morini really nailed the balance here. Bravo!
The Persian-style blade with its distinctive polished swedge nods to classic pike or clip-point shapes – but here the false edge runs almost the entire length of the blade. Careful: this knife is pointy. And by pointy, we mean really pointy. So pointy that Bastard Knives had to reinforce the leather sheath just to prevent the tip from poking straight through. Smart move – and honestly, pretty necessary.
Speaking of sheaths: you get sturdy leather with a titanium clip. Leather for tradition, titanium for everyday carry. That way, the Xerxes rides comfortably in your pocket.
The blade steel is CPM-3V: extremely tough, highly resilient, and wickedly sharp. Just give it a little care when it comes to rust, and in return you get a knife that won’t back down any time soon.
The handle comes with screwed-on Micarta scales, available in green or natural. Micarta feels great in hand and only gets better with age. Screws instead of glue mean you can take it apart whenever you need to clean it after some hard use. At just 17.5 cm overall, the Xerxes is not only compact but also fully 42a-compliant.
If you’re into compact, lightweight EDC fixed blades but want something with a bit more character than the usual suspects, the Xerxes should definitely be on your list.

There are knife makers. There are knife makers who are true artists.
And then there’s Stefan Steigerwald.
The “Mad Professor” of the knife world regularly invents folders that make everything else in the knife cosmos look like mere background props. His creations, shaped by retro-futurism and steampunk aesthetics, are fine mechanical masterpieces – complex, playful, and yet somehow perfectly usable for everyday carry.
The Aronax Slipjoint, developed in collaboration with Bastards Knives, is more than just a namesake: Professor Pierre Aronnax was the main character in Jules Verne’s classic 20,000 Leagues Under the Sea – one of the most important steampunk novels ever written. And when you hold the Arronax in your hand, you can almost imagine grim Captain Nemo himself pulling it from his jacket pocket.
You can choose between two fascinating variants:
Brass handle scales with satin-finished D2 blade
Titanium scales with stainless Magnacut blade (ideal for a damp engine room deep under the sea)
The handle scales unmistakably bear Steigerwald’s signature: playful Art Deco elements combined with a clear, almost industrial design. The textured recesses provide a secure grip, while the milled holes in front of the pivot screw evoke an old steam engine – small details with great charm. The proprietary hardware blends seamlessly into the mechanical look – with a particularly clever touch: the pivot lock on the clip side, as if taken straight from a Nautilus construction kit.
The clip itself is a small mechanical revolution. Thanks to an integrated spring underneath, you can press it down like a rocker – no snagging, no scratching, just a smooth slide into your pocket. Sounds simple, but it’s executed so elegantly you almost feel like applauding. The sheepsfoot blade opens with a satisfying walk & talk – a little mechanical ritual in its own right.
The maritime influence of the sheepsfoot blade is no coincidence: the small ramp at the end of the spine gives your thumb a secure rest, while the subtle “horn” toward the tip provides a precise finger rest for detailed cutting work – whether on deck, underwater, or at your desk.
The package includes a microfiber cloth and a sturdy pouch with patch panel.
