I've bought numerous knives from O/S including axes, though luggage on planes & over the internet and to date never had one problem (I used to import for the company I worked for also, have lots of great free samples never seen in Australian retailers, even a few not kosha

).
Plenty of parcels opened with customs tape reapplied but all delivered by Australia Post.
I have around 150 odd knives, all good brands my favourite multi tool is the Schrade Tool, so far the only one without some problem it has laminated plier jaws. The majority of my knife collection are Puma knives.
The one I wear daily around the farm is an ex army army pocketknife with bakealite grips made in 1940 in Sheffield, an extremly tough knife.
All knife nuts should do a week in Seki City in Japan the cuttlery capital of Japan home of the Samuri Sword, just don't mention the war.
