Material
Grade 5 Ti-6Al-4V. Not titanium-coloured.
Most wallets sold as titanium are commercially pure Grade 2, which yields at around 345 MPa, or anodised aluminium wearing the name as a colour. The K-1 is Ti-6Al-4V — the aerospace alloy, 895–950 MPa — and every unit ships with the mill certificate for the metal it was cut from.

In motion
The same object, moving.
A short clip of the K-1 being handled, so the finish and the thickness read the way they do in the hand.
Filmed on the same teak deck. No CGI, no stand-in prop.

Scale
Pocket-sized, and shown that way.
Photographed in daylight beside a house key, so you can judge the size before you buy rather than after it arrives. Nothing here is staged larger than it is.

Before you order
How a pre-order works.
Build and delivery
Every K-1 is cut to order, not shipped from stock. Production takes 14–21 business days from the start of machining. You get an order confirmation immediately and a shipping notification with tracking when your unit dispatches.
Returns
Returns follow the store policy shown at checkout. Before your unit enters machining you can cancel for a full refund.
Pre-order terms
An order reserves a serialised build slot in the current run and releases the material for it. Payment is taken at order. Cancellable for a full refund at any point before your unit enters machining.
