I think someone answered this question before, but I can't find it searching the archives. With Starrett combination squares, what is the difference between models with the glossy black finsih and ones with the wrinkle finish? TIA Eric

wrinkle ones are cast iron, while the smooth ones are forged hardened steel.

Thanks--I had searched the Starrett website but couldn't find the info.
Now...which one is preferred, or considered more accurate/durable?
depends on your use. IIRC, cast iron is more dimensionally stable but steel wears better.

True. I think you'll also find that the really old ones all had a smooth finish.
