In simple terms, an Izula will not collapse on you while being used.
A folding knife can.
Additionally, the Izula is made from a steel which is known to be both durable and excels at holding an edge.
The Paramilitary or Military as bladed with S30V have a distinct issue with the edges folding over. S30V has a long and glorious history of this and has from day one. It is the nature of the steel. It is a shite steel for knife use, regardless of what Crucible says. Knives are made to cut and a folding edge will not do this. The composition of the steel at the molecular level ensures that while it will be "tough" (and that is a very interesting question as well) but the crystals will shift to avoid breaking and this causes the edge to flop versus stay in place.
D2 may or may not hold an edge, depending on the heat-treat.
Both steels are far less capable of taking lateral pressure or impact than 1095 and the Rowen/ RAT heat treat is sensational. You've seen a lot of stories in here about what we could term as retarded use or abuse of a knife.
Note that the Rowen blades handle this sort of behavior repeatedly and consistently.
The Izula will be stronger than your folding blades, and let me tell you, folks laugh at the pink Izula, but it's not grabbing attention the way a big folder with a shiny or serrated blade will in public. A liner lock of any sort is in no way as safe or secure as a fixed blade.
Get the handle scales while you are at it. You can sell one of your folders and easily cover the cost of the Izula and scales even at the aftermarket price of your folder.
And as some of the fellas have mentioned, an RC3 is an even better all-around carry-all-the-time knife (I hate the term EDC and would willingly kick whomever invented it in the balls) - it is of a perfect size to just tuck it IWB with the clip outside your belt and forget about it until you need it. It's also a very low profile knife.
