A holster device for securely holding a tool can include a stationary retention feature and a sliding retention member securing a first portion of the tool and pressing a second portion of the tool against the stationary retention feature. The tool is retained to the holster device between the stationary retention feature and the sliding retention member. The holster device can be configured such that a force applied to the tool moves the sliding retention member away from the stationary retention feature and releases the tool from the holster device.
