I have ordered from Knifecenter about 6 times over the last 3 years and have always got my knives. Customer service can be a bit lacking at times but the price makes up for it. Generally they may take a while to fill the order if the stuff isn't in stock and they seem to have problems responding to emails.
Usually wait 2 - 8 weeks for an order with 3 weeks being about the average if everything is in stock.
Generally, I can get the knives at half the price of the equivalent in Aust. Also can usually buy what is not here at all.
Recentlt bought a Spydie Military for $112US which is $224AU plus have to pay freight of about $20US = $40AU.
I usually order for freinds and more than one knife/tool etc so the freight costs are lower.
Assuming it was only the military, the price would be $260AU. The price at the outdoor shops is currently $425.
At these prices you can afford to make a few mistakes. The only downside is that you can't play with them before deciding but I think that just adds to the excitment of waiting. Also forces you to do some heavy research into the products before buying.
WARNING: don't get to greedy on your orders as when the amount gets too high ( $500 ? ) or too many, Customs start taking a closer look and charge you import duty plus GST. Still works out cheaper but is extra you can avoid.
Only happened once with $1000 order and a freind of mine with other non-knife merchandise.
Hope this helps
