Saw something on the TV last night and thought I would stir things up in the New Year.
It was all about carbon and there was a very interesting section on how carbon fiber is made. The guy said carbon fiber is ten times stronger than steel and at least 3 times as light as steel! So for all the posts about fears of carbon fiber failing, and there are many, it seems your fears are misplaced.
I am going to look for a carbon fiber hammer to replace my Estwing!
