    I needed to cut trough a THICK, rough-edge of sidewalk after a crew jackhammered out our pathway for me to lay paver stones. This blade was FANTASTIC. Was exactly what I needed.(I first went to Lowe’s home improvement and their “tools specialist” recommended the WRONG blade, a grinding blade. The concrete chewed it up in 2 passes and only got me to 1/2 depth, even wetting it to keep it cool…So much for Lowes’ expertise! Eye roll.)This blade was PERFECT for the job. Plan to use it for all my cuts for the 16”x16” pavers as well, and don’t anticipate any problems at all.ETA (10/10/2022) pathway’s almost done and this blade shows NO signs of wear at all!Steps for DEEP cuts:1) The first time you use this blade or your saw, make a first pass thru your BLACK MARKER line @1/4 or 1/2 inch depth. This cut can be done DRY (yes, you’ll see a few sparks probably; but it’s no big deal for this blade). **The purpose of this step is to allow YOU to learn/check that your sight line on the front of your saw is accurately cutting. Repeat this depth until your line is perfectly straight.2) while you let your saw cool for a minute, fill the area with a cup of water!3) Adjust your saw to a deeper depth, cut it along the SAME line, and let it to cool for a min.4) Just repeat that to your max depth.**IF your piece is deeper than your saw’s depth capacity: dig out underneath the concrete, as far as you can under the cut line (so the piece you’re cutting off is essentially hanging out above the ground underneath, without “support” from any dirt below it). Use a heavy sledgehammer or some large stones dropped from head height, and the concrete WILL eventually release.
