The "quickdraw/ iaido" technique, for swords/katanas/wakizashis/etc specifically, as is depicted in loads of games, comics and anime, especially Rurouni Kenshin.
I get that this is a legitimate sword fighting technique, but the way its depicted in fiction is nigh impossible, its often depicted as being much faster AND more powerful to draw and slash in one motion, than to simply slash with the sword drawn, which is quite inane.
Well it is much faster in perception, you essentially go from a non threatening sheathed sword to a full swing, that is an awful lot of time saved compared to unsheathe - prepare for swing - and then swing, time which gives your opponent a gigantic telegraph of incoming attack.
But it is obviously not strong, at the most masterful level you can maybe get the power of one hand into it and to pull it off at all you need to be insanely skilled.
It is much like the western movies favourite revolver quickdraw, of course anyone can try it but to actually hit anything even close to your target mere moments after you pulled your gun and shot from the hip would require thousands of hours in training.
Obviously in entertainment everyone becomes Superman... or better.
