re: Three really large 18th century style chisels

Do you mean that the small end of the tang protrudes through the end of the wood handle is enough to ensure the wood handle is safe from normal use?  I can’t see any metal at the end of the wood handle.  

You should just say these are just display chisels and build some real chisels when you get some time. 

We don’t mean to be critical of your work we just want you to make quality items.
