I've got a really narrow cold chisel which I am using to remove the
mortar between my bricks prior to repointing but some of the bricks
are really close and I need something narrower - about 4 to 5 mm
wide.

Does anyone know where I could get one as I've so far failed in my
search.

This has got to be a job for an angle grinder.
