howdy all, new member here with a Regulator question. I have a new to me Hollow Regulator from blade 2014 with the parkerized finish. Was this the only Regulator made with the parkerized finish? Reason I ask is that it seems the Hollow Regulators are .300 thick vs the other Regulators are .333 thick. Kind of important difference when ordering a sheath.

Thanks for any and all help.
