Vallorbe HSS Gravers Flat #8

Hello All

I have been using Vallorbe HSS gravers for about 20 something years
and have been buying them from our local tool shop here in New
Zealand but have recently been buying a few tools in Los Angeles. In
New Zealand I can buy Vallorbe flat gravers number 2, 4, 6, 8, 10,
12, 14, 16, etc these sizes correspond to the mm size 0.2, 0.4, 0.6,
0.8, 1.0, 1.2 etc As far as I have seen so far these numbers are
written on the side of all Vallorbe flat gravers no matter where in
the world you buy them.

In all American tool catalogues I have seen so far they are listed
as 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46 But they skip number 8
or 0.8mm they go from 0.6mm to 1.0mm & at the LA tool shops they tell
me the number 8 does not exist.

I know it exists because I can buy it in New Zealand. Can anyone
explain this to me. Normally its the other way around, things exist
in
other countries and not in New Zealand.

Any direction to where I can purchase Vallorbe 0.8mm flat would be
appreciated.

Thanks
Phil W
