Yes a 5" blade is a compromise at both ends and I've gone back and forth. For me, I've found a 5-5.5" blade just about the right size to carry comfortably without being too cumbersome when on duty or out in the field/outdoors...and I'm not carrying another fixed blade or larger chopper (machete/axe). I can do the small knife jobs and it will "chop" better than a 4" blade, but isn't as difficult to carry and work with as larger bladed knife. There are pro's and con's to this that we could debate for weeks...the bottom line is finding something that meets your requirements and a knife/sheath system that you can comfortably carry and move around with. Either with a backpack or combat load out, anything over ~5" gets in the way of the gear and affects my mobility. 5 inches just gives me a good feeling

(that didn't come out right!) I will carry a shorter 3-4" blade if I really need to go light or if I have a larger knife in the pack, but there's just so many good choices for a mid-sized knifes
