I was just browsing the current (March/April 2006) issue of Fine Woodworking, specifically Crhis Becksvoort's article on "Keeping Tabletops Flat".
As I looked through the photos I was very surprised to see him using slotted screws. I checked closer and see three pictures where he is driving a slotted screw.
Being thoroughly Canadian, I use Robertson (square) screws almost exclusively. I will on occasion use a Phillips screw, but only rarely (eg: Drywall screws are all Phillips, for some reason). But I will NOT willingly use a slotted screw.
I have heard a few people claim that a "well-matched" slotted screw will grip the screwdriver well, but in my experience that has not proved the case. I've slipped, gouging myself or the workpiece, or just dropping the screw, far FAR too many times.
So, I'm curious, do you use slotted screws? Why or Why not.
And please, pardon my Canadian ignorance, but have Robertson screws still not really penetrated the US market?
