There are lots of implements that one could use to clean dirt out of one's fingernails, and while on vacation, one could forego the need for a small knife, but if you really want to know the law on the matter, it is technically illegal to carry a knife unless you are carrying/using it in the pursuit of earning a livlihood or other lawful activity. It is unclear if just carrying it in your pocket to clean your fingernails constitutes a lawful activity under Philippine law, and since you will be a tourist you would be well advised that regardless of your financial situation you would be looked at as being wealthy and ripe for exploitation by corrupt members of the Philippine police force.
You would be best advised to leave your pocket knife at home...but do what you wish at your own pleasure or peril.
