Abstract: A stand-up gun safe comprises a substantially vertical, but moderately tilted, spine that supports one or more hinges, which in turn support two shell components that rotate relative to the spine and swivel relative to each other. In a closed configuration, the respective edges of the two shell components abut each other, creating a secure seam.
