The hook started in '83 and remained pointy on most of the 4s (except SBs) until 2012ish. They dulled the hook on all the US 4 strings after that. Fivers with 4+1 headstocks like the Kilo 5, L5000, L5500 and first year L2500 are pointy too. The 2500 changed to 3+2 shortly after release.
All the Trib 4s look like they are still pointy.
The USA JB still has the full point.
