Shamrock‘s in-game description.
Shamrock is an unobtanium tier knife skin in The Mad Murderer 2.
Shamrock particles


Shamrock has a green and gold blade with curly patterns, a red leather grip with golden rings around it and a golden pommel in shape of a four leaf clover. The hilt is made of gold and has two emeralds and a realistic four leaf clover attached to both sides.

The blade emits soft white glow and small sparkles, while the gems on the pommel emit green particles that travel a pattern very similar to a four leaf clover.
