I've been setting tile for over 25 years, and this trowel is great for large format tile. I've owned multiple of this exact same notched trowel, from different manufacturers, and because this particular trowel blade is thinner, and less hard of a metal then all my other trowels, the notches tend to wear away quicker then all my other thinset trowels. This notch is similar to a 1/2"×1/2" notched trowel. Great trowel, just wears away kinda quickly because it's not a very hard metal, and metal is thinner then other professional trowels.
