I concure with the suggestion to go to Bladeforums. Also I have trained with Bob Taylor and have practiced and used a Hobbit warrior and pocket hobbit and a Crawford Carnivore since they were first available.
Any knife to the average citizen is intimidateing. The Hobbit/Warrior series are all very intimidateing due to the nature of thier design.They are very effective CQB blades. The other knife you might want to look at is the escilator that was designed by Bram Frank. All of these knives have a certain tecknique and you need to prcatice to get familiar with it. The Hobbit series are the easiest to master and practice.
Sorry for the length. I strongly suggest you log onto Bladeforums.com.
