Primarily the saw does not produce an accurate cut on a 10" wide board, as the saw blade is not 100% parallel to the sliding mechanism: this means the kerf is not an even width from the back of the cut to the front, producing a 'wobbly' cut. Having spoken to Evolution about this, they say that the saw is not designed to produce such accurate cuts, as it is not a joinery saw. Evolution insist that first and foremost the saw is a multi-purpose saw designed to cut many materials, one of which is wood, and that the saw is for first-fix work, not accurate second-fix. The reality is that this saw is merely designed to cut a 10" board, not cut a 10" board accurately. MY MISTAKE! I bought this saw thinking it would be sufficiently engineered to produce accurate cuts, as I need to produce all sorts of work from first-fix to second-fix to the odd custom kitchen cupboard. I think it would be better if Evolution clearly stated the saw's accuracy on its website, or was I supposed to deduce that a multi-saw is just an inaccurate rough-cut saw?
