Really three knives would be better. I use one of these a lot. I've got them stashed in strategic places. One's out in the Implement Shed, another in my basement workbench, one here by the 'puter, one in the garage. I've got one of the sheetrock/utility knives that they replaced out in the chicken house for opening feed. It's one of the handiest knives I own.
Wish it was made here.
