What are you going to be doing at the hospital? If you are working in an office, I'd say a small case or SAK without a locking blade would be fine. Even a Ladybug size knife. If you are working in Maintenance or something like that, I don't think it will be an issue, but a multitool would probably be appropriate. If you are on the floors as a RN, LPN, Aide or something like that, well then either be really careful or talk to a supervisor. I work as a CA (Aide) in my hospital but don't "carry" anything. However, my Dragonfly and my Wave are in my bag which is near me all the time. If anyone has a problem with it, they've never said and they love my Wave because I've pulled it out several times to fix stuff, open boxes, etc. I am actually looking to get one of the Juice or Squirt models so I can carry it in my pocket and it won't weigh me down. I would NOT pull something out in front of a patient. But, talking to security or your boss would be the way to go. After you work there for a while and you find you have need of some sort of cutting tool, then ask if you can use a small SAK or pocket knife. They probably won't care.
