Going to echo the Buck recommendations. Have a buck folder that never leaves my pocket. Gets screaming sharp with just a work sharp field sharpener, holds an edge well and is inexpensive enough that I wouldn't feel too bad if I lost it. I know they make some fixed blades out of higher end steels, might look at those if you prefer s30v/magnacut/etc.
