Walkabout:
1. Wardog
2. 411
3. Swamp Warden
End of The World:
1. 1311
2. S5
3. 311
And as stated, this is not an Always these, but could change on a whim.
Randy, you cheated a little

. HOWEVER, I wanted to cheat the same way you did, because I break down knives into those same categories.
I like the fact you have a small, medium and large for TEOTW. I've always believed in the blade trifecta.
To follow your lead, my 3 Walk Around & 3 TEOTWAWKI would be...
WALK AROUND1) Busse Leaner Meaner
2) Swamp Rat Warden
3) Busse Boss Street
TEOTWAWKI1)Busse NMFSH (this will eventually get replaced by a Battle Mistress)
2) Busse ASH-1 Skinny
3) ScrapYard 411
