If you look really closely, Peter Fields Brass Keyhook is nothing more than four pieces of solid brass. One 2.1cm diameter brass ring. One flat, 3mm diameter split-ring. One long piece bent so it has two hooks, and one thinner piece wrapped around the hook to hold the rings in place. When all those solid pieces of brass come together, it makes a damn cool accessory for holding your keys. Simplicity isn’t always the best option, but Fields take on a minimalist carabiner is phenomenal.
