7" Blackjack #1-7: my primary camping blade for years.
7" BK&T BK7: now gets used in the Blackjack's place.
Both of those get used for light limbing, convenient carry for cutting stickers and vines out of your way in heavy brush, and with a baton for sectioning wood, or splitting kindling and firewood. Both are lighter and more convenient to carry than a hatchet, and have a wider range of use. They're probably not ideal for any of the things I use them for, but are great all-around tools when you'd rather carry one versatile blade, than several specialized ones.
9 13/16" Busse Basic 9: my "heavy" beater, used for thick brush, small trees, limbing. It's mostly for clearing, and yard work, and hasn't made it on a camping trip because of its size.
14" BK&T Patrol Machete: for clearing smaller stuff, especially briars (we have plenty) which make the extra length welcome.
16" Ontario machete: preceded the Becker, but doesn't get used much any more-doesn't even have handles of any kind on it at the moment.
All of my "normal" use is with smaller knives, ranging from 2.5" to 4.5", but there are some things those smaller blades just can't do.
