I would stab myself with one of those!
First pic I says to myself, no way that fits. Second pic I admit to myself that it seems dangerous but my life expectancy would be considerably shorter. Third pic, I went back to pic two and made up my mind, no. Like getting a folder that the handle doesn't cover the blade or carrying around a pocket full of gunpowder.
It's no worse than a fixed blade dagger... but the blade gets longer when you want it to.
