Nibless Creasing Tiles

“What are nibless creasing tiles?”, I ask my brother Ric.
They top brick walls, directing rain away from grout.
“Named after inventors then?” we ponder right thick.
Perhaps Mr. Knibbless and Kreesing, we spout.

“Maybe it means not pointed and creased”, says nephew Jus,
“As in not pointed and making a kink in the water flow”.
The internet concurs, it’s not confusing, there is no fuss
They’re not pointless those creasing tiles though,

They’re nibless and they crease the brick walls just so.
