You can take them as luggage, and they may or may not be safe.
What some folks do is get a lockable rifle case, and a TSA lock ( just like you would do for a gun). Take it to the TSA inspection station and tell him you have a case of knives to be inspected , locked, and sealed with a TSA seal. Most of the time they will comply. That makes your case go as priority handling luggage and everyone who handles it has to sign off for it.
The other way is to send the knives insured either by UPS or USPS. Send them well in advance with tracking, and when done with the show, ship them back the same way. If you have a friend in the area who has a business addres sto ship to it is better than shipping to the hotel ( unless the hotel specifically offers this service).
