I want to have my kitchen worktop as a base unit end panel too (it's actually a breakfast bar). But I don't want to see the edge of the breakfast bar with the worktop beneath it, I presume I have to use a circular saw set to 45 degrees in order to acheive this 'no edge' look. I'd rather buy a router bit as the edge finish will be much crisper (even if I cut the worktop upside down with the circular saw). Am I trying to acheive the impossible? is there a better way?
