Get a Victorinox farmer. It might not impress the hell out of your friends but it will do everything you mentioned as well or much better than any tank-like tactical folder, and it will last a lifetime because instead of abusing your blade to dig or pry you can use the reamer or screwdriver blade which are made for such things. A leatherman would be even better. On a side note holes > studs and the Endura has an extremely robust tip. If you're looking for a 1 hand opening knife with a strong tip the Endura 4 can't be beat for the price. The farmer can be found for under $30 online, and the Endura will run $45-50.
