I was just rounding the edges of end grain on a project, when I saw a
few sparks coming off of the router blade. The wood is a tropical
wood like teak. I had sanded the edge before I started routering. So
it could be coming from a trace of sand or the wood.

Has any one else had a similiar experience?

Yep. But from homemade wood not imported. Apparently from hard
wood, routing too fast, and applying too much pressure. Been quite
while,don't recall what type of wood.

This happens when you are splitting wood with an axe--if you do it
after sundown when you can see them.

Would these be electrical flashes I wonder?

Static electricity and all that?

I doubt it. Electrical sparks generally go from one object to another.
These just fly out like a spark from a flint.

Not electrical in my case, and I'd been routing for a few seconds,
so seriously doubt static 'lectricity. Definitely saw the spark fly
from the bit. However, it is possible that I was using a HSS bit, not
carbide tipped, at the time. I only used HSS bits for a short period of
time and now use only cabide tipped. Only had that happen the one time
- that I know of.

I was a using carbide tipped bit when I saw it. It was like described
as a spark for a flint.
Thanks to everyone for their responses.

Maybe. Or embedded metal staples, barbed wire from
eons ago, etc..

You can get this effect from breaking a Wintergreen Certs in half. It's
