Advice please for my new kitchen installation. The worktops are solid wood, walnut butcher block. I have 2 corners to make, and the choice is butt join or mitre join. I think the mitre joint will be the neatest finish and would prefer this. Is there any reason that the butt joint would be the choice, and is there any risk in making a mitre joint in the solid worktop? I will be employing the services of a joiner to install the worktops.
