Each country has different laws and customs regs. AU is bad for daggers ,which are illegal and even a false edge on a bowie is close enough for them to stop it.
I never had a issue but I know several who had. I know of a VERY expensive collector knife that sat in a custom storage in Noway for so long it was rusted badly.
I make sure I am read up on each countries knife laws and customs regs before sending.
