    Cache (kash) [noun]

    1. a hidden place for provisions, valuables, treasure – as used by explorers or adventurers

    2. a secure place of storage

    The Wingback Key Cache is designed to enhance and complement your everyday carry, while discreetly adding functionality. 

It neatly clips onto your keyring and contains a secure compartment to store banknotes and an “if found” note in case your keys go missing. Having emergency cash tucked away will spare your blushes if you forget your wallet. It could even save your bacon on your travels – a backup $100 note can get you out of a lot of tricky situations. Machined from a solid bar of aerospace-grade stainless steel, the Key Cache has been designed to last for decades, not months. For video instructions on how to fold the notes to fit inside, click here.

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

    Keyring: As above (included with your Key Cache).

    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)

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

    Engraving: 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. Just remember to carry your diamonds in a separate pocket!

Just what I needed

The Key cache is just brilliant. I was looking for something I could use on the key ring of my motorbike keys. Somewhere to stash the note for the refreshments on the long day trip. No need for the bulky wallet sitting uncomfortably in my pocket. The design is elegent yet rugged which suits my purpose brilliantly and it has already been a talking point on the coffee stop on my last ride out. Outstanding :)

Craftsmanship Counts

Love my Key Loop and Key Cache from Wingback. Beautifully machined and with a great finish that’s going to age well. Can’t wait to see the mechanical pencil!

Key Cache saved my night!

I was away for a business trip, went out with some friends but left my wallet in the hotel. After a moment of panic I remembered I had the key cache attached to my keyring. The £20 stashed away got a taxi back to my hotel and a massive reduction of blood pressure.

A couple of tips:
- Keep the key cache attached to an object that’s on your person at all times. Go for the most ubiquitous object. Keychains are great, although you might also attach it to a belt loop, a backpack, or an EDC pouch.
- Depending on what you attach it to, think about the attachment method. A ring is great for a keychain but a carabiner is better if you’re going to attach it to your jeans, or a paracord lanyard if you’re going to put it in your bag.
- I think all the metal options look great, but the Black Steel version I have feels luxurious, doesn’t scratch, and it doesn’t draw attention to itself (which is crucial).

Fantastic

I bought this as a 50th gift for my brother, he loved it, the workmanship and feel of it really appealed to him.
