Was sawing thru some plywood and heard the saw change pitch for a second, took a closer look and saw what looks like a nail or thin piece of metal embedded between the layers of ply.
I've never come across this before, has anyone else?
The ply is of unknown origin as it came with the house, nice enough tho with what looks like a cedar decorative outer layer. Bit hesitant to keep using it if its going to dull all my saws!

They don't. But some workers drop things when manufacturing it.

What about a flitch beam?

Since when have they been plywood GD? They are laminated, yes. This looks like 27mm ply with a veneer. What size beam are you talking about? Smallest is normally 40mm.

Keep using it and worry if you find a second bit of metal.

Plywood is laminated timber is it not? But yes, I’m taking the piss.

Run a stud finder over the plywood. However the metal is quite small. A tungsten carbide blade cuts through nails very well without damage to the blade.

Different glues used, but the same principal. Not like you to piss take?

Unless running the same way, been there done that. In the centre of a log, 6" nail perfect line with bandsaw blade.
