Thank you all for the warm welcome and replies.
I own many firearms, several modern and several "traditional" arms as well. When I am afield with my traditional guns I tend to carry more "period correct" accoutrements. But I'm not a huge stickler about it. I have some things in my pouch that are definitely modern... even an old Tic-Tac container for carrying small parts.
But after a day of shooting I take the guns back to the house and retire to my bench for cleaning, care, maintenance, etc... So I'm looking for a fairly comprehensive screwdriver set for my bench to cover any work done on any of my guns, modern or otherwise.
FDR's suggestion is pretty much what I'm looking for.
But a traditional, hand-forged turnscrew is on the list to carry in my pouches. Because, well, I want one.
Thank you again for the help. I am sure to post more in the future. Looking forward to more responses as they come.
Mike
