In my limited experience the cutting is slow going and the dust is
nasty. I would not use a good saw and I would - did wear full face and dust
protection. The saw I used was an old Sears I bought as is about 35 years
ago for $3.50. Nothing will kill that thing.

You can get a dry Diamond blade for your saw, There was a water feed made
for a circular saw at one time. If they still make one that would increase
the blade life and cud down the dust. When they did our granite the used a
dry diamond blade (6"to 8") in a grinder, I have used a 4" grinder ( some
times called a peanut grinder) with a diamond blade to cut tile and stucco.
If you use a regular abrasive blade I can't imagine how long it would take
or the dust but I've never cut Flagstone.

They still have the water kit and roller attachment at Amazon.com and other
sites. I've used abrasive blades before, slow and ware out faster than you
could change it - diamond is the only way to go.

Limestone is quite soft, a resin masonry blade and your saw will work
just fine. Just go slow and easy, don't force. Forget a diamond
blade...they make dust too and it would be silly to buy one for one cut.
IMO, YMMV.

Possible but I use my circular saw with a masonry blade occasionally to
cut concrete caps - about the same as your limestone would be as far as
hardness and abrasiveness - and haven't damaged my saw. Clean it well
after, blow out dust from the inside too.

The last one In retrospect dumping the salt OUT OF the bags into wheel
barrow ( clean) spreading around the pool with shovel might of been a better
idea, to bad I didn't think of that.
