First of all, I have to loudly object to this arbitrary 3 knife limitation. That is a blatant violation of the constitution's "more is better" clause, as well as the pursuit of happiness.
But rather than getting into a supreme court hearing on the matter I will reluctantly abide by the criteria set forth. Under protest!
I too will see if I can produce a $50 all inclusive budget, if only to show congress how it is done.

Prices are my last prices paid.
Dress knife - SAK Army Classic SD $13.80
EDC - Kershaw Hotwire $9.87
Fixed blade - Old Timer Lil Finger $17.65
total $41.32
And that Wash DC, is how you keep within budget!!!

From dressing out a deer, to opening packages and daily cutting chores, to clipping loose thread from mi'lady's dress, these three will do it all.
I doubt I could put a better list together with my more expensive, more preferred blades if only because I could not pick out just 3. No way, can't be done.
EDC - I've got more than 6 in my rotation. Top 4 would be Kershaw Atmos, CRKT Ruger LCK, Ontario Rat 2, and Kershaw Hotwire.
Dress knife or Gentleman's knife - WAY more than 3. Top contenders are Northwoods Norfolk, Opinel 08, AG Russell Lightn' Bug or Gentleman's Pen knife, Boker Plus Panatela, Kizer Feist, Puma IP Armino, Kershaw AM-3 or Squaw Creek, Case Peanut, Lionsteel Roundhead.
Fixed blade - Definitely can't be done because I require 2 fixed blades at the very least. One conventional hunting knife and one Bird and trout knife. I currently own at least 20 bird and trout knives and 30 fixed blade hunting knives. Fixed blades were my first knife love. And you want me to pick just one....

For a B&T I would probably have to say, my Horsewright / Dave Ferry Sonoran Belt knife. Though I don't know how I can not take my Menefee 16 bore, My Arno Bernard Maribou, or my Moki B&T as well. Got 2 more that are inbound that may make the top list as well.
For a conventional fixed blade hunting knife, My Buck 102, (first sheath knife) Cabela's Boker Tree brand hunter, Boker El Trampero, Companero, or Rancho Madera, Benchmade Saddle Mountain Hunter.
Pick any one from each of the 4 groups and I'm good. But still wishing I had all the others.
