What are these chisels ???

I Was looking at the lee Valley website the other day as one does if one is tool junky.

And I came across these.



Perfect-Pattern Handled Chisels - Lee Valley Tools



Perfect pattern handled chisels.

They look like mortise chisels to me.

Or am I missing something?

Could any one shed some light on what they are intended for ext. the quality if you have a set. Are you happy with them?

Sorry if this seems simply question but like I said I have either missed something completely.

Or I'm just having a moment lol.

Or both.
