Each knife is individually numbered on the backspacer. The handle scales are hand-engraved and flame-colored, so variations and signs of craftsmanship are to be expected.

Please note:

• All sales are final. We do not accept cancellations, returns, or exchanges.
• Each piece is unique, with visible signs of handcrafting. If you prefer a more uniform, factory-style finish, this may not be the right fit for you.
• Due to high global shipping demand, delivery may take 20–30 days, with possible delays depending on your location.

Thank you for your patience, your support, and for being part of this cosmic journey with us.

Each Cosmic Neuron Parallel begins with the titanium handle meticulously engraved to form branching, neuron-like pathways — an intricate web echoing both life and the cosmos.

The handle is then carefully heated to around 450°C (840°F), developing its mesmerizing spectrum of deep blues and purples. This rich cosmic backdrop enhances the engraved patterns, making them appear alive with depth and motion.

Finally, the central nodes are selectively reheated at a lower temperature, around 250–300°C (480–570°F), until they shimmer with a radiant golden hue. These glowing focal points evoke the firing of synapses, capturing the spark of energy coursing through a vast cosmic network.

From engraving to controlled heating, every step of the Cosmic Neuron Parallel is designed to create a living piece of art — a fusion of precision, imagination, and the mysterious beauty of the universe.
