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.

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!
It takes a few days to make each product to order but this ensures every item is one of a kind and nothing goes to waste. We aim to dispatch all orders within seven working days and often a lot sooner. You'll receive an estimated dispatch day in your order confirmation email.

Black Steel rivals the exotic look of Damascus steel or titanium, with a sub-metallic lustre that reveals a glimmer of the steel beneath the surface. It is applied using a technology called magnetron sputtering, where nano layers of tungsten carbide carbon are deposited onto the steel surface. Finished in Cambridge and laser engraved, assembled and packaged in London, all items can be personalised and made to order. It takes time, but so does anything worth holding onto.
With a surface 9x harder than stainless steel, 3.5x harder than titanium and incredibly low friction, our Black Steel items will be scratch resistant to virtually anything you will put in your pocket. Parts and mechanisms should never need to be maintained, let alone replaced. They will work as well for you today as they will for a grandchild who might inherit your collection in decades to come.
Arrived quickly and is a great quality product. Well with the money

Father’s Day gift
I purchased the steel key cache as a gift for my partner for Father’s Day from our son and daughter! He loved that I had it engraved with emergency ice cream fund. Was a personal touch. Great gift and great service

Key Cache - Brass
Really great item. The quality of materials and attention to detail are second to none. Your customer services (Megan) are great too - I had also bought a Winston wallet (under a separate order) - Megan was very helpful in ensuring both items shipped together.

I've previously submitted a review for the black key cache which never made it on to the review site. Looks lovely but by the time it was assembled onto the key ring there was already 'flaking' and loss of the black colour cover. Not sure this is particularly resistant.
Thanks for getting in touch, your previous review is indeed on our sight with a detailed reply from me. I explain why we can't coat the two items in the same finish and why we then include a steel key ring with every black steel purchase.
Take a look as I believe this will clear things up for you. If you have any further questions please get in contact with me via email, email@example.com.
