The "pruning" blade (AKA "Hawkbill") is also great for linoleum, carpet, drywall, electrical wiring, and so on.
A sheepsfoot, lambsfoot, and Wharncliff are good when making straight and precise cuts (leather, thick foam, etc) as well as sharpening pencils and whittling.
Drop point, spear point, and clip points, are good for skinning critters, and general cutting needs. These are probably the most versatile.
The "Spey" blade is obviously good for it's intended purpose, and skinning critters cleaning fish, and budding/grafting. Some also like it for whittling and carving.
The Coping blade is good for that, and whittling.
The punch/awl (usually found on Scout/Camp knives and SAK's) is useful for making holes in your belt, scribing lines, (wood, metal, plastic, leather, drywall, etc) opening bottles or jugs of oil, antifreeze, and other items with a seal under the cap.
The combination cap lifter/bottle opener flat screwdriver is right handy for bottles without a twist off cap. (there are still some of those in use, by the way)
The can opener is good for that, and scraping paint and other stuff near the window glass and in tight corners.
There are, of course, other blade profiles, but I think these are the most common today.
The experts will be along shortly to correct my errors.
