Well, I was lucky enough to make sure my partner is only about 10 cm shorter than me. But still when I renovated the house, it ended up the way that they cannot reach everything...
Not really a mnemonic in German, but I once learned how to remember of the moon was in first or third quarter by comparing the form of the crescent with the Vereinfachte Ausgangsschrift cursive letters "a" (abnehmender Mond, first quarter crescent) and "z" (zinehmender Mond, third quarter crescent).
The same applies to screws watching from the top, cursive "a" is for "auf" (open) and "z" for zu (close). By reading the comments, this is somewhat the closest you get to your mnemonic.
I forgot to mention I do not catch everything, preferably I avoid catching knives. And iron pans. Hammers also not. For some reason, my brain did a pretty solid job not to catch such items.
I regularly catch stuff that accidentally drops nearby me with my hands or I manganese to soften the hit in the ground by changing it's trajectory with my feet.
That doesn't prevent you from trying tho
