best method to cut worktop

Small electric saw and a lot of care.

If you have a router, cut oversize with saw. then clamp a guide to the worktop and finish smooth running hee router against that.

If possible tile over the end to hide any messes you made..

Turn worktop over. Mark cut and use a circular saw but screw a batten at a suitable distance from the mark (use the saw as a measure) as a guide to the worktop. Always start the cut from the poist formed edge and don't force the cut, if possible use a finer (40tooth) blade. Always support the worktop on both sides of the cut. If you cut upwards through the laminate surface there is little chance of damaging the laminate.
