Talk:Razor blade steel

[Untitled]
Reference 1 is not related to the article. Upon reading the reference material ( US international trade committee), i found that it clearly states in the footnotes that "this journal does not apply to razor blades" that is under the introduction section.

Wanted to know the date razor blades were invented. — Preceding unsigned comment added by 122.106.155.172 (talk) 12:36, 23 April 2012 (UTC)

Iron must be greater than what article states. It is steel.
