Abstract
An example coring tool includes a cylindrical body having a leading edge to contact a substance and a cavity defined at least in part by an inner surface of the cylindrical body. The inner surface is to engage and retain a sample from the substance with a plurality of raised features. The raised features are shaped so that at least one of the raised features or an exterior surface of a sample in the cavity deforms to increase a force required to remove the sample from the cavity.
