[CAUT] Knuckle Direction

[tnrwim at aol.com]

I know the line indicates the direction of the nap of the leather, but which way 
s preferable.

That's the big debate. Some manufacturing say the nap should allow for the jack to return fast, some say the nap should alllow the jack to escape fast.

OK, maybe just too much week-end or perhaps old-timers....
I am re-knuckle-ing a set of grand shanks. The new parts are of Able manufacture 
nd have a pencil line on each. 
Does this line face the flange or the hammer?
