I've added a Stanley "SportUtility Outdoorsman" knife... It's not the highest quality thing out there - not by a long shot - but it's a big bladed folder (3 1/4") combined with a standard, "boxcutter" utility knife.
It's definitely a cheap knife, but it's also one that I'm not afraid to abuse. And the cheap main blade lasts a lot longer because the disposable utility blades do most of the grunt work.

There are many reasons why you (or your company) might not want that. Accounting, for one - do you want to pay for work calls/does your employer want to pay for personal calls?
Privacy - does your employer need to know the phone numbers of all your friends and family?
Legality - do-not-call lists apply only to private numbers, not business phones.
I handle it all with one phone as well, by forwarding everything through Google Voice, then having Google ring me. But there are many reasons why one might want multiple phones.
I think my Dad's case is very different from yours. He's now a Funeral Director for a home in Georgetown where he works with a friend of his. His employer pays for his phones, since he does route them to him, he's one of the 3 people that answer calls, and you'd be surprised how many people call at 3 am trying to discuss a bill.
