A cutting element assembly, comprising:

• a sleeve having a leading face and a trailing face;
• an inner cutting element at least partially within the sleeve, the inner cutting element comprising a diamond table attached to a substrate, with the diamond table having a cutting face of the inner cutting element, the inner cutting element further including a rear face and at least one side surface extending from the cutting face toward the rear face, the cutting face of the inner cutting element being within the sleeve and between the leading face and the trailing face of the sleeve;
• and
• a blocker retained in the sleeve with at least one locking device, at least a portion of the blocker being between the cutting face of the inner cutting element and the leading face of the sleeve such that the at least a portion of the blocker covers a portion of the cutting face of the inner cutting element and restricts movement of the cutting face of the inner cutting element toward the leading face of the sleeve.
