A honeycomb extrusion die (10A) comprising a die body incorporating an inlet face, a discharge face opposite the inlet face, a plurality of feed holes (13) extending from the inlet face into the body, and an intersecting array of discharge slots (17) extending into the body from the discharge face to connect with the feed holes (13), the intersecting array of discharge slots (17) being formed by the side surfaces (20) of a plurality of pins (19A) bounded by the slots (17) and extending into the die body from the discharge face, wherein at least some of the side surfaces (20) of the pins (19A) incorporate at least one geometrically designed flow-modifying surface discontinuity (21).
