Ontario Knife Company has some even better images at their site. The "newer" survival knife comes in three different styles, all with nylon sheaths as opposed to the leather of old, which I've found has a way of rusting the knife. They also have the "old-fashioned" ones for the purists out there.
I really like them, especially considering the prices are reasonable.
There is one, I think it is the SP-8 machete, which looks great and also feels nice in the hand but when actually used is not all that great. A plain old Military surplus machete (all I have seen are also made by Ontario) works much better.
