[TheForge] Re: File making in Japan

[Grant Marcoux]

I use a lead bath to temper the tangs of my hand made files, but not to
harden the body of the file  Grant

Andy didn't say this was not case hardening - he said modern files are
hardened in lead.  That's not what is happening here.  This is a hand cut
file process using old methods and it still looks like case hardening to me.

I with Andy,  I think it is highly unlikely that hand made Japanese files
are case hardened.   The Japanese are noted for their very high carbon, very
high quality steels used for hand tools, woodworking blades and such.
