This is what Jacob at http://BladeHQ.com
wrote back to me in email:
"It is legal to carry and own, unconcealed (i.e. pocket clip must show), an
automatic knife in Utah. I do not know if a CFP allows you to carry a knife
concealed. We do not require any sort of military I.D. to purchase. You are
welcome to come to our Lehi store and handle the knives."

His response coincides with much of what I found on the internet, except he clarified what unconcealed means in regard to these knives.
Can anyone verify that the pocket clip showing means the knife is unconcealed? What if you sit down and your shirt covers the clip?
Now someone needs to do more research to see about whether or not a CFP holder can carry one of these concealed. Someone wrote an eBay guide that indicates their opinion is that it is ok. http://reviews.ebay.com/Quick-Reference-Guide-to-US-State-Switchblade-Laws_W0QQugidZ10000000007130677
The federal laws around automatic knives can be found at http://en.wikipedia.org/wiki/Switchblade
. One of the laws "prohibits possession on Federal lands, Indian reservations, military bases, District of Columbia, Puerto Rico and other protectorates." Be careful in Utah if you end up getting one of these knives because there is lots of acerage the federal government owns that is scattered around Utah, so check a detailed map when you leave the cities and towns just to be sure you don't accidentaly carry an auto knife on some plot of remote federal land 50 miles from civilization - or even driving to your your favorite fishing/hunting/outdoor recreation spot.
"The Federal Government owns nearly 650 million acres of land - almost 30 percent of the land area of the United States. Federally-owned and managed public lands include National Parks, National Forests, and National Wildlife Refuges." This .gov website has very basic maps showing federal lands and indian reservations state by sate to give you a general idea for where you can't carry your auto knife. http://www.nationalatlas.gov/printable/fedlands.html#list
