@@claytonpompeypickersomerse8205 The Parker Jotter pen is the cream of the crop for inconspicuous objects :) Paper clips can often work, depending on the cuff design, they'd work a treat in yours. Paper binder clip things can also similarly work, though less so in British handcuffs which have 3 pawl bars. I have a Leatherman Micra tiny little multitool which I sawed the knife out of and epoxied the nub in place to remove the knife and I snapped one end of the tweezers off and the remaining one I bent a nice little scoop on the end and filed it slightly thinner and that works wonderfully as a cuff pick.
@@claytonpompeypickersomerse8205 I would recommend pulling or scraping the bobble bit off the end to prevent it coming off in the handcuff. There's a small chance it might get smushed into the mechanism. Also for general picking, I like to use a little knife sharpener stone to smooth the rough edges so that I am not scratching/wearing the mechanism, though for survival capability you wouldn't care about scratching up the mechanism of a captor's cuffs lol. Just a couple little ideas for you.
