This is a brand new set of Piranha Golf Performance Cavity Iron heads, .370 hosels.
This is from my friend Jim Battin. They are very similar to the Infiniti KO irons ftom a few years ago. Infiniti used 431 ss, and Piranha uses 301 carbon steel per their website.
Update: the heads are actually 4-GW, not 5-PW.
The 5-PW set is gone
