Serrated Tactical

the best way to sharpen a knife? HOW AND WHAT? Knife brands?
I wanted to know the best method as to sharpening a knife (tactical buck folding knife)
It is part serrated, but all I really want to know is how to sharpen the straight edged part.
what type of sharpener should I use, what direction do I push the blade,etc?
Is honing oil necessary or is water ok to use?
also wondering what brand of knife I could look for if I wanted to buy a really nice one with an edge that will last more than a day or two (as this one wears out quickly)
Thanks for you time
my dad has a 3 sided sharpening stone that works Great. it takes me like a minute to get a good edge and like 10 minutes for a razor sharp one if your good at it. its a Carborundum arkansas stone
o and yes use oil water wont work well and will probably ruin your blade
