Hi,

That’s odd 😀

A few questions:

What iron is it (size, make etc)?

What chip breaker do you have on it, and is it a match to the iron?

What angle did you sharpen the iron to?

What is the sound like? E.g. vibration, grinding, scratching etc?

Can you attach photos of the iron, chip breaker, plane sole?

Cheers

Darren.
