Key Cache - Black Steel

The Key Cache is designed to carry a small but vital cargo: emergency cash, a note for safekeeping, or essential medicine. Its machined knurled surface ensures a tactile grip, and the hermetically sealed compartment keeps its contents safe and dry.

The Black Steel version is finished with an ultra hard, scratch resistant 4µm tungsten carbide layer which is 9x harder than stainless steel, and usually reserved for high performance cutting tools.

Metal: Aerospace grade 303 stainless steel from Europe, CNC machined in Birmingham, UK. Tungsten carbide carbon finish applied in Cambridge, UK.

Keyring: Stainless Steel

Sleeve: Oeko-Tex double thickness cotton sleeve from Poland, Europe.

Finish: Laser engraved, assembled by hand and packaged in London, UK.

Dimensions: 40.50mm x 13.6mm diameter (outer), 31mm x 10mm diameter (inner)

Weight: 22g (0.8oz)

Capacity: Fits GBP, EURO, USD and every other note we have tested (the maximum size we have tried is 160mm x 82mm)

Engraving: For added personalisation, you can engrave up to 25 characters on the bottom, with a name or contact info so your keys make it back to you if they ever get mislaid. All inscriptions are in capital letters and run around the base of the Key Cache

Considerations: The Black Steel key cache retains all the precision and corrosion-resistant qualities of stainless steel, while the tungsten carbide finish increases the surface hardness 9x. Any marks it picks up from regular use should be easily wiped away. However, the surface is scratch resistant, not scratch proof. Anything harder than the surface (diamond, some ceramics) or really aggressive use will be able to scratch it, but most items you would carry in your pocket shouldn't (for this reason we supply the cache with a Stainless Steel key ring)Just remember to carry your diamonds in a separate pocket!
