360 crank knurling?

Back in the mid 80's I got a 440 crank from Hamburger and it had no knurling. That's all I say.

So Hamburger knew back them.
Eagle still knurls their forged cranks as recently as a year ago.
Scat does not knurl their forged crank for 360 stock stroke, the only one I have seen in person.

Knurling is definitely not needed.
