Ok in this case I hate to name names, but I'm kinda forced to. I carry a Gerber 600 multi and a Gerber LMR fixed blade. The LMR is long since discontinued but has served me well for many years. They're of moderate price and good steel. Find what works for you, use it and practice with it. If it fits your needs, keep it.

I use a fine diamond Steel for sharpening. I test by shaving my hairy arms. If it will shave in one stroke, it's sharp.
