Hello all. I am very grateful for all I have learned by just reading the posts on this site. However there are some acronyms I am not quite able to place. Would some kinds souls please define some of the terms used here-heck I don't even know the ones I don't know!

For exampe: DD, DE?? What are these?

I have figured out the following:

WTG: with the grain
XTG: across the grain
ATG: against the grain

Maybe an index of wet/straight shaving terms can be made sticky somewhere.

As always, thanks for your help.
