Well, i... sharpened my pair of cheap chinese VW screwdrivers earlier tonight using my cheap diamond “stone” (two-sided #400 and #1000 grain).
After having finished my business (sorry i didn’t plan to post about that at first so i took no photo before), i got to play with the “new” phone (Galaxy S10) macro capabilities, using an additional watchmaking magnifier in front of the phone (that we can see in some photos).
Using the 2x zoom, it sometimes (depending on the lighting i believe) switches between the main sensor and the tele one which wasn’t the most practical when having the magnifier half in front of the other objective and holding the phone on one hand and the magnifier on another (and having to tap the screen for the focus).

Second screwdriver :
It’s not perfect but sensibly better than before which was already totally acceptable but i like to have an “aggressive” blade that can come in handy when you need to remove gunk inside a screw head for example.
