Sharks fins are welded in a way that the shaft does not heat up so much and reduced its hardness.
All shafts pass through heat treatment and the metal acquires high hardness, durability and reset memory.
At the Medium and Large Shark fins the 2 holes are at the second shark fin and at the end of the shaft.
At the Small Shark fins the hole is at the end of the shaft.
