Abstract
An elongate bunker spike that secures a flexible golf bunker liner to the earth strata when the bunker spike is driven through the bunker liner into the earth strata. The bunker spike has a point member adjacent to the axial forward spike end, a ribbed member adjacent to the axial rearward spike end and wherein the ribbed member is contiguous with the point member. A head is at the axial rearward spike end wherein the ribbed member joins the head at the underneath surface. A barb extends from the underneath surface of the head whereby the barb engages the flexible golf bunker liner when the elongate bunker spike is embedded in the earth strata.
