Dull small flat screwdriver usually small cheap plastic handle w/ strong 3" long steel flat blade, appox 2mm wide, sharp edges all worn round to vague shape of a tip and a medium chemist's steel (stainless steel?) labware spatula w/ vinyl dip coated handle. The blade tip is rounded like blunt dinner knife instead of straight edge and strong enough to resist bending when prying hard. All edges is dull not to catch on the plastic too much. The blade width is such that it's narrow enough to fit through slot opening to push in the internal catch like on samsung 750S, 753DF etc monitors models and also use this tool to pry both halves, pry large plastic hook apart etc. I have yet to break any plastic catches unless it was already fadiged from damage, abuse or age. Oh yeah that one screw IBM snap together dot matrix printers, that's was really clever design! These is one of those are not a problem for me to work on them. The major killers is the remotes! I had bad time getting halves apart without breaking at least one hook, my hands isn't strong enough to squeeze hard or out of fear especially crushing it and splintering it. What I like is quality japanese screws like usually used on Panasonics, JVC etc, and designed in a way it comes apart easily and enough wire lengths to extend out to flip the board over to probe for signals. RCA and few others was great except for certain items. So not all are 100% perfect. Cheers, Wizard
