The old left-vs-right circular saw debate… Stuart from ToolGuyd did a great article about this, concluding that he hopes manufacturers will offer more options.That makes sense to me. If you're right handed, you hold a 2x4 with your left hand and cut on the right. So the waste is usually to the far right. So yes, if you needed to trim, the sole on a leftie would have only a tiny perch. Also, a left blade would be closer to your face than a right blade.
Looking at the market today, it’s mostly blade-left for rear handle (worm drive etc), blade right for 7 1/4”, and blade left for 6 1/2”, and this goes for both corded and cordless. If there are exceptions in the current market, I’d be curious to know about them, especially if they’re corded (so I don’t have to join a battery club).
We’re an M18/M12 household, flirting with Metabo HPT multivolt, because of the triple-hammer impact and juicy pricing for the MHPT 36V circular saw.
(oh, and, surprise: the MHPT 18V 6 1/2” saw is blade-right, I guess that’s one exception to the pattern.)
