I recently had to cut and fit around 11m of oak worktop in my kitchen and utility . This included 3 corners (butt jointed with 3off dog bones and biscuits for alignment), a gas hob and 2 sinks, I went through 3off trend c153 1/2" cutters for all of this, the disposable ones that cost under a tenner each.
I used a fresh cutter per worktop butt joint to ensure the cut edge was perfect. Then used the worn cutter for the respective cut out (hob, sink etc). I used the most worn cutters for subsequent dog bone joints.
It worked for me. If I was doing it for a living I am sure there are professional grade cutters that last longer etc, but I hopefully won't be fitting a kitchen for a while now!
