Hi Jim
At first I thought that this was a April fool joke but unless you have a Kapex it is not such a silly question...
In operation (ie when switched on and the blade is turning) there is no difference for right or left handers. The Kapex power switch and safety trigger lock are symetric and operate the same for left and right handers. Sighting the work piece and the lasers is the same from either side of the saw.
There are other controls that are used to set the saw up for a particular operation which are not symetrical and will be different for left or right handers. However, as these are just 'settings' there should be no technical challenge for either a right or left handed person.
The clamp can be positioned on the left or right of the saw (or in both positions if you have two). So you can clamp the work piece with the left hand clamp, hold the other end of the work with you right hand and use your left hand to operate the saw. Or, you can use the right hand clamp, hold the work with you left hand and use your right hand to operate the saw. I am right handed but I operate the saw in both ways depending on the nature of the cut.
Although I am right handed I still use a left handed pencil and find a left handed tea cup more comfortable. [smile]
