If you are thinking you could afford a Sebenza some time I would wait for that and get an inexpensive folder like the Buck or S&W suggested above.

I have a Microtech LLC that cost about $170 that I believe compares nearly to a Sebenza for blade utility. It's lock is no where near the Sebenza. But for half the cost you have a very well made knife.

I carry a small Sebenza everyday in my vest pocket and would never be without it.
