WD-40 and or Dish Water.
 
Is it on the blade or handle? For the blade WD40 or Gum Cutter should work.
 
you mean rubbing them on boobies doesn't work?

WD takes it right off before it dries. After it dries I use hot water and soap then WD
 
Goof-Off (roughly 50% xylene and 50% toluene) will cut through and dissolve dang near anything.

If it is pine pitch on your knife, turpentine (a distillation of pine pitch) cuts it fast & clean. Mineral spirits should also do well, as will the lacquer thinner that Randucci mentioned.

Some organic oils work surprisingly well on pine pitch as well -- olive oil being the one I used on my car's windshield once with good results removing fir pitch drips, albeit needing a little elbow grease to get it all off. You could try other cooking oils like peanut oil, corn (vegetable) oil, sesame oil, etc.

I've also used 409 spray and other ammonia sprays to get gunk off blades, then rinsed thoroughly with water.
 
What kind of tree was it? If evergreen, the sap will be best dissolved by the various solvents mentioned above. If it was a deciduous tree, then the sap is more of an aqueous sugar solution, and soapy water or common household cleaners should do it.
 
Rat beat me to it. :D I swear by Goo Gone. Takes grease stains off of my Goretex jackets, too.
