Do not pull a razor blade from its protective cover, in such a way that the edge of the razor is passing right across your own boob. Just don’t. This advice is gender neutral: this is not how a sword is to be handled.
With a katana it is critical, at all times, to know where the back is and where the edge is. After all, if you confuse the two, you can destroy parts of yourself pretty easily. Also, you want to block with the back/offside of the blade and not the cutting edge. But, in general, understanding blade facing is one of the most important aspects of surviving handling a sword. I have lost control of a sword twice in my life – one time, I chipped a chunk of bone from my right index finger (that’ll teach ya!) and the other time the blade whacked hard into the side of my lower leg; I stood immobile for 20 seconds with my eyes closed, not looking, waiting for the pain – as it happened, I hit with the back, not the edge – but I had lost orientation so I didn’t know how I had hit myself!
See that draw she’s doing? Since the scabbard (saya) is curved away from its intended direction, if she tried to complete that draw she’ll either cut into the wood on the edge-side of the saya, which could result in it breaking apart and then the blade would go right into the tendon that formerly held her thumb on. Fortunately, that’s not a real sword; it’s a wall-hanger. Being stupid with a wall-hanger is what wall-hangers are for.
I cannot imagine that this picture impressed anyone in the NRA. Oh, wait they’re gun nuts… In other pictures of Maria Butina she’s carrying guns, and correctly keeping her finger off the trigger. So, at least she’s not omnincompetent.
“omnioncompetent” – damn, I like that one. Did I invent it? A quick google indicates that may be the case.
