Koichi/Echoes were never pierced by Black Sabbath's arrow, the only time Gold Experience got stabbed thru the hand was to protect Echoes in the first place.

"Gold Experience has been pierced twice by Arrows but only once did it evolve into a Requiem Stand"

Silver Chariot also was pierced two times and only fully became Requiem once, as Polnareff was able to cancel the transformation the first time by pulling the arrow away from Chariot's hands, King Crimson as also pierced and didn't became Requiem because Chariot Requiem's death pulled him away from the arrow.

"It is possible to break an Arrow and render it ineffective. This is largely implied to be related to the insect-like carving on the flat face of an arrow, which, if intact, will be usable. "

Source pls, outside of those "Complete/Superior Arrow" fan theories the manga never gave any importance to the carving on the top of the arrows, as it's said that is a virus that lives on the rock that grants a new life ability.

Moreover, Jotaro didn't make a ammulet with the arrow, he put a small fragement of the arrow inside the ammulet without any carving, so the "as long as the insect carving on its face is intact and it is able to pierce its target" doesn't make sense.
