We've got the opposite problem here in Germany.
According to a new law, you're not allowed to carry folders in public, but fixed blades with a blade length of less than 12 cm (4.72 inch) are allowed as long as they're not classified as "weapons".
In theory, this means that carrying a CRKT P.E.C.K. might get you into trouble, but a Böker Rampage might be okay
I used to EDC a waved folder but had to switch to fixed blades due to the new law.
The difference in comfort is huge. If I carry a folder in my pocket, I barely notice it's there, even if it's the size of a Chinook. Furthermore, it's always accessible.
Fixed blades - unless they're very small, such as the HAK - are much less comfortable to carry, especially if you carry them concealed (which is necessary if you live and work together with sheeple, as I do).
If you carry a knife in a MercHarness, you can't just take of your jacket without people noticing it. If you carry it IWB, the knife becomes less accessible as soon as you put on a pullover or a jacket. This gets even more of a problem if you carry a neck knife.
I am currently EDCing a 3-4" fixed IWB and/or a very small fixed in my pocket (IMHO, best place to carry any knife), but if it wasn't for the new law, there would definitely be some folders in my EDC rotation.
I am very confident I could deploy a waved folder just as quickly as an IWB fixed blade.
