Snap-On Roto/Swivel Head Changes?

[The Critic]

Did Snap-On recently update the FHNF100 with the new Cynergy design? These ratchets have been 100 tooth since their introduction in 2009.

Any time I've seen Snappy make a change, they add a suffix letter to the part number.

Part number unchanged probably means the tool is unchanged, but maybe they're tying all the 100-tooth ratchets together under the silly name
