I am struggling to source a GOOD hexagonal or square shafted screwdriver to remove bottom blade screws which are slotted c'sunk 9/16" (14.1mm) wide heads. This would allow wrench or spanner use to give me extra torque. Searched "t'internet"....faced with usual myriad offers guessing at what I am really after.
Does anyone know of or have a recommended manufacturer or source where I could buy one? If so can you send me web link so I can find?
The screws are stubborn little b.....ds! And its now descended into my will versus theirs! But I want the right tool for fear of mashing them up and having to drill out. I have applied heat a number of times.
