Probably, all you need to do is to copy the eyelander attributes to the weapon you want.
Edit: The attribute seems to be this one

                "max health additive penalty"
                {
                    "attribute_class"    "add_maxhealth"
                    "value" "-25"
                }

Wich translated with the attributes table, it is:

"125"        "-25"
