I have not tried it on wood. Since it scribes glass and metals, I would think it would work on wood.
The scribe is for metal.
It will not work to cut glass.
You use it like a pencil to scratch the surface you want to make a mark on.
Yes it should work.
The KH537 is good for scribing glass.
This tool has a tungsten tip to mark on metal, glass, plastic, and tools.
The KH537 Scribe is sharp enough to make cuts into hard surfaces and leave clear marks on metal, glass, plastic and tools. It is only intended to score a glass surface, but probably not enough to cut it. It is not a glass cutter which would cut much deeper.
No, this scriber is not recommened to be used for scoring ceramic tile. Its intended use is to WRITE on metal, glass, plastic and tools. It would not be appropriate to handle the application you are describing.
