No b-52s, but P-38s are common.The old P-38 is hardly obsolescent or just for opening cans.I've used mine for fish lures,emergency ice cleats,splitting roots for cordage, sewing thimble and small vise for holding needles and matches. Canned rations and water are still in widespread use worldwide A good stropping with a ceramic rod helps.Occassionaly larger European versions are offered for sale among the surplus retailers. Some have had bottle openers, spoon handles etc.<br><br>
