I am a right hander but like using left bladed saws, it’s a line if sight thing and frankly I find right sided saws auckward. I really like worm drive saws but they are just heavy to run all day. I find it sad that other than 6 1/2" battery saws and worm drives there are only two “normal” left blade saws to choose from, don’t get me wrong both are good well regarded saws but seeing all the bells and whistles put into less costly right blades bums me out. Oh well Bosch CS5 you’ll be mine one day… and hopefully one day DeWalt make a brushless 20v lefty I’ll own that in a heartbeat, heck I’ll probably still snag the regular 20v anyways.
I think it is mostly a line of sight/ preference thing. Either can essentially be used lefty or righty, but I believe the products are being designed around the idea that people will use both hands when cutting, and that just doesn’t happen. More often than not that ends up being a more awkward position to cut, and you can’t grab the piece of falloff.
Another reason I haven’t heard mentioned, is I believe all track saws are being made blade-right, so I wonder if that has caused any manufacturing or other benefits to making all of their standard saws blade-right.
Yeah my festool tracksaw is a right side blade. I dont understand that either. Still think there is a reason for it, perhaps it is the both hands thing that you said, or perhaps it’s not having an open part of the blade showing your direction.
Maybe framers actually use it lefty and hold onto the piece with their right hands? Could be the nature of the job.
That bosch is a beast. 15A too. I bet that’ll rip through some hardwood all day where my makita 18v would freeze up. When I lean over my workpiece with a right side blade I can still see the leading line of the baseplate for direction so could be it’s line of sight for one handers.
Seems like both of you are on the same page with line of sight. I dont disagree. But there must be some other reason. To protect the left hand on a one handed cut? dunno.
Lots of urban legends about this topic - but you are probably right - and while the first portable circular saws may have been worm-gear ones (if you believe Skil) - the cheaper first direct-drive sidewinders may have started as right-sided - and it stuck.
One theory - often espoused - is that with a blade on the right - you hold down the work with your left hand, operated the saw with your right hand and the cutoff piece falls away to the right. Maybe this is somehow more natural - but maybe it was just a sinister (from the Latin) plot.
As you point out the corded Milwaukee 6391-21 is still available as an exception - and the old Porter Cable 345 seems to still have a bit of a cult following despite its odd-sized 6 inch diameter blade. FYI - not all worm-gear saws were lefties - with my PC 9314 (AKA PC 314) trim saw being an exception.
What I’ve heard a while back is that right-hand or left-hand has to do with not crossing the blade with your arms.
With a right-hand saw, your right hand is on the main grip, left hand on the aux grip, and blade is positioned to the right of all that. It’s similar with a left-hand saw.
But when a righty uses a left-handed saw, the right hand is on the main grip, left hand is on the aux handle, and your left arm crosses over the blade. The blade is aligned between your right hand and your body. Yes, the cut line is more visible, but it places the blade inside your arms, rather than outside.
In such a position, if your left hand holds a workpiece and your right holds the main grip, you could in theory accidentally put the blade in contact with your left hand.
I just bought my first circular saw, the cordless brushless makita. Xsh03 I think is the model. After using my dads circular saws for so long (all of them being corded and thus blade right), blade left just feels like the opposite (I mean it is the opposite lol, it just feels different). Maybe it’ll just take some getting used to.
Maybe WE start a petition or open letter to the tool companies stating we WANT left blade options. With support from our little community and folks like @ToolGuyd and @benjamenjohnson we might get some traction and get the ball rolling. ???
Don’t drag me into this I find blade left and blade right circular saws equally awkward.
I mainly use a circular saw to break down sheet goods in my garage before I bring them downstairs into my shop. I have a corded blade right saw and a cordless blade left saw.
I usually clamp a straight edge as a guide so rather than watching the blade I’m making sure the base of the saw stays against the straight edge. I push a right handed saw with my right hand and a left handed saw with my left hand. I’m weird.
thinking more clearly, I meant that if I’m using the saw on the left side of the straight edge I use my left hand, right side, right hand…regardless of the type of saw.
Apparently, dewalts research found that their focus group preferred blade right when they came out with their 60v circ saw. However, I know of people who will not buy it, even if it is the most powerful cordless saw, because they prefer blade left. Most people I know prefer blade left, so I was just assuming I guess.
Most people are right handed, therefore when you using the saw right handed, there is no chance for the left hand to be cut by a saw with blade on the right side.
When the blade is on the left side, sawdust is thrown all over you, compared to having it on the right, where it can be directed away more efficiently,
Majority of the saw base is supported with a right side blade so you are more likely to get a vertically square cut as you are not relying on the waste that you are cutting off to keep the saw square. Especially if you are just cutting a couple of mm of the end of a piece of timber and there is nothing to support the right side of the saw.
