Let's see... Yesterday, a go to town workday, I used my knives (I EDC 4) to:
open packages
break down boxes
open my mail
cleaned my fingernails
open a fertilizer sack
peel an apple
cut a piece of twine
Today, a work on the farm day, I:
cut the seed heads off Johnson grass that was too tough to pull out
chopped down a 4 inch tree with that "large, heavy knife" known as an ax

grubbed out some mesquite stumps using a mattock and then used a MK2 to cut the smaller roots
cut the seal disks out of some bottles of motor oil
cut heavy twine for bundling up brush
cut open a bag of frozen chicken
peeled an apple
cut zuchini and summer squash and green beans in the garden
removed the rattles from a rattlesnake - no I am not THAT hardcore

- I shot it with a 357 loaded with rat-shot first.
