Amusingly, the Dragon's Tooth sword in Deus Ex takes up more room in your inventory than a normal sword (4 spaces as opposed to 3), even though the wield animation clearly shows you pressing the button and the sword springing to life. It's a handy weapon, but it would be handier if it took up a comparable amount of space as a pistol. Placing an engaged Dragon's Tooth in your pack in RL would be a very bad idea, seeing as how they are nano-sharp and would cut all your guns in half.

It's hard to beat the amount of damage done in a short period of time by a Dragon's Tooth sword in the hands of a master swordsman, which makes it perhaps the ideal weapon for dealing with tougher enemies (the ones that don't blow up as soon as you kill them, that is).
