If I may offer some advice, starting with a ZDP-189 fixed blade when you know virtually nothing about knives can be a mistake. All steels have pluses and minuses. Take your time.
FYI, I have several knives with ZDP: that steel is very sharp but can be brittle and is usually used as a core to a laminate of more flexible steels. For a fixed blade, you should post on that sub-forum: they will give you advice specific to fixed blades.
I agree with Sonny that Spyderco is an excellent brand, as is Benchmade, for the novice (as well as enthusiasts).
I am reading the downside on ZDP-189. A thread that someone else created in this forum.

AND thanks everyone for welcoming me. I like this forum as well as ABF.
Before I get another knife. I would like to try sharpen the existing knives that I have just to see how sharp can they be and how long will it last if I use it daily.
Did some research and most of the people uses diamond rod to sharpen their knife followed by a strop. Is strop really necessary? I believe it smooth out the edges of your knife after a diamond rod is used?
