Abstract
A core catcher for a coring tool comprises a sleeve comprising a longitudinal axis and at least one slit extending at least partially along a height of the sleeve between an upper end and a lower end thereof. The at least one slit separates a first side surface and a second side surface of the sleeve. The first and second side surfaces are located a first distance and a second distance from the longitudinal axis, respectively, measured in a direction transverse to the longitudinal axis. The core catcher further comprises a bridging element extending at least partially about a sleeve perimeter. The bridging element operatively couples movement of the first side surface and the second side surface to limit a difference between the first and second distances as a width of the at least one slit that separates the first side surface and the second side surface increases or decreases.
