Are you speaking about the "standard" sheaths with Greg's stamp or his "actual" x-d out (seconds)? I cannot address the seconds but Greg has a new "rectangular stamp he is using with "Odessa, Fl." as the city. Could be your sheath was in the transitional mix Tom. (???) I am going to see Greg on Friday and I'll try and remember to ask him. We (Greg, Danny and I) have a lot to go over, including some new "sheath news".
Anyway: I have no idea if I answered your question or not...but I hope so.
Best, Capt. Chris
