Welcome Newbie...
It's nice to "see new faces" here. You will find some of the finest people on the board.
My little bit of advice... you might want to handle the knife before you buy. See if a friend or acquaintance might have one already. Consider buying from a "brick and mortar" store if your budget allows it.
The above mentioned retailers are all reliable outfits so buy with confidence, but you might want to check the exchange section as well. You will need to be a bit more careful there, but if you ask around, the people here will be happy to point out who is reliable and who is not.
