Thanks Ren, but won't the tile carck when hit by the spike ?

I am thinking ceramic tiles. Slate tiles are made of some type of rock aren't they ? They would crack , in theory at least ?

I use this hammer as a carpenter hammer and never used the spike for anything, but I am thinking about it now. There were times when I made holes in sheet metals ( like metal shelves ) and used a concrete nail for that purpose. The spike on this hammer will make a bigger hole than I want.

hmmmm
OK, maybe venting holes for homemade stoves !!
