meh.
I'll take the Raker Ring Tool over that thing anytime..
Hello Miodrag-The picture of the tool you have here is indeed the T-Rex. It is a very early prototype of the Z-Rex we will be selling to everyone in about a month. You can find that tool on our site now: http://www.leatherman.com/product/Z-Rex. We never sold this tool you have and could not have used the name T-Rex. It was trademarked by someone else and we found out after we printed up those 100 samples. We decided on the name Z-Rex instead because the cutters now are in the shape of a Z. The prototype you had was made out of 154CM and features a cutter, but you cannot replace it like the new Z-Rex. There is a Hex driver and an oxygen tank wrench on your T-rex, just like the current Z-Rex, but no large hole for your small end finger to go though as an extra precaution for holding on in slippery or shaky situations. Also the new Z-Rex is made from aluminum and the handle is rounded. The T-Rex is one solid piece. I hope these answers help you. The tool you have is a sample prototype and one of a kind. There were only 100 made.Have a good weekend,Juli
