Slant Ridge Trowel....

[White Room]

I've got 2 sizes and find I use them more than any other trowel

used it on a few floors with wet u/f as it is supposed to give you better heat transfer to tile because of 100% coverage thus preventing air pockets. I was going through adhesive like never before. I went back to my 10mm round notch as it eats less and with the right prepped floor always gives me good coverage

Was looking at them recently, look a good job. How well do they wear? Would imagine the thin blades wouldn't last too long with everyday use.
