Personal choice item, very hard to say that what would suit me would be good for you. I have some case, boker, victor inox, but wind up carrying a cheap Japanese made pocket knife most of the time. Loss or breakage? No real loss, dang thing won`t break though, like 25 years.
Real hard to find quality in some styles, like to find a out the front with a 2 1/2 inch blade.
