You suspect correctly. I have a chrome-plated parade M1 Garand bayonet on the way to me this week, as well as one of those inexpensive but nasty Swiss bayonets with the scabbard and frog to match. I also have one of Pabooger's Ka-Bars brand new, among a number of other tactical models.
The one I'm most fond of (and won't carry) is dad's WWII bayonet, with leather grip and leather tie still attached. But I bought a new M1 carbine bayonet which serves just as well. One fun buy I made a while back was an 1889 Belgian bayonet SOG sells with 11" blade and a quillion -- for only $12 -- it polished up great and I sharpened it as well -- only problem is no sheath, so it hangs on the wall. I should probably buy a couple more of those while they last.
I have a number of other new tactical models, a couple Swiss Moras, even a Kukri and one'a them Rambo sized jobs you need a shoulder harness to carry. It will take some time switching off and wearing the modern tactical models around to settle on the one I truly find most comfortable and useful. Luckily, there is no limit on blade length for a carry knife in Indiana, though power-assisted openers are illegal. But it still pays to conceal a serious knife, as one does a gun.
And yes, I have a few tactical swords as well and am looking into a few other variations...
