When you say switchblade, do you mean 1 blade or two? What size quad are you looking for? The micro inductrix or the eachine e010 are often modded by cutting two of the four blades off. some people say it helps performance. You could buy a pair of e010's for around $30 total from eachine and mod the props on one of them to be 2 blade. They actually come with extra props, so you could do other expirimentation as well. I don't think it would fly right with a single blade, but maybe?
Ive never seen a store bought quad that provides different props. They are all engineered for the weight of the quad so only one design is necessary. But I can tell you the more blades a prop has the more lift, if the pitch, length and rpm is the same. But theres also more work involved for the motor and most motors are designed for a particular rpm range. Im sure a book can be written on this topic alone.
