No contact with maker?

[M&J]

Now approaching 2 years, I'd ordered a knife to have originally been completed middle last year. The maker relayed he'd had complications and that this would be the delivery year. I've sent several e-mails without contact thus far regarding progress. The mails haven't bounced and we've written each other in the past. I haven't called due to time zone challenges, he works a day job so by the time he's off, I'm long asleep.

Your suggestions on what you might do to determine whether the knife will be completed?
