The product of a years-long collaboration with Chen Chen and Kai Williams, the Sidewinder is an enigmatic kinetic sculpture moonlighting as a knife.

Named for the oscillating tracks left in the sand by its serpentine namesake, motion is at the core of the Sidewinder Knife’s design philosophy. Rather than a fixed handle, it has an interlocking mechanical hilt, with two opposing elements moving in sympathy with the blade itself to produce a truly unique unsheathing mechanism.

Formed entirely of stone washed and black PVD-coated stainless steel, the Sidewinder boasts a heft that feels authoritative in the hand, but never unwieldy. It’s perfectly pocketable, but remains equally content to be displayed on a desk, a shelf, or a mantle, proudly soaking in the wonder and admiration its curious form will undoubtedly attract.

Frequently Asked Questions

What materials are used to make the Sidewinder Knife?
The handle is stone washed and black PVD-coated stainless steel and the blade steel is 12C27N.
How is this different from a typical knife?
Part sculptural object, part knife, it has an interlocking mechanical hilt, with two opposing elements moving in sympathy with the blade itself to produce a truly unique unsheathing mechanism. No other knife is like this.
Does it lock open?
Yes. The liner lock securely locks the blade in place when opened for safe, stable use.
Is it TSA-approved?
No. Like most blades, it should be packed in checked luggage when flying.
When will my order ship?
Orders typically ship within 2–3 business days (excluding holidays), unless otherwise noted on a product page. Once packed and ready for pickup, you’ll receive a confirmation email. Orders confirmed after 2 PM EST usually ship the following business day.
What is the return policy?
We offer free returns and exchanges on eligible domestic orders within 30 days of delivery.
Can you ship the Sidewinder Knife (or any of your knives) to the UK?
No. We do not sell or ship knives like the Sidewinder to customers in the United Kingdom. UK law places strict rules on the sale and delivery of bladed items (including mandatory age verification and restrictions on residential doorstep drops). Because these rules make selling and delivering knives into the UK legally complex and high-risk for retailers, we do not offer shipping of any knives to UK addresses.
