Gendai Measurements ;-)

My American Fellows

I was wondering what system do you all use to measure your blades, seeing as
no-one really wants to use shaku and Japans secondary unit is CMs. I believe
that you are doggedly keeping the feet and inches part of imperialism (as
well as gallons), is this still the case when it comes to Japanese swords,
or do you make the exception in this case and use the metric system?
