i think the entire slave army had the butchers nails.

as emps was heading towards the planet wouldn't he have gathered all available information in regards to that world? so he ought to have known about the practice of slaves being implanted with butchers nails. maybe it simply came down to his thought of - "those slave warriors have been augmented to their detriment (detrimental in terms of cool and calm thought processes) as candidates for the astartes process. angron has also been 'nailed' but he's my 'son' and i wont throw away such a potent asset."

or maybe he was hubristic and wouldn't allow his armies to be modified by anything other than his own techniques.
