What was the hardest thing to find?
The harder ones to find off the top of my head are:
SDDP123 long shank #3 screwdriver (new)
24 inch ratcheting screwdriver (new)
SDD42 with pouch and the 4 shanks (new)
Most of my stubbys. (I have 11 of them)
SDD104 stubby flat tip with 3 1/2 inch handle (new)
SDDP234 stubby Phillips head with 4 inch handle (new)
My metric nut driver set. It is now a 7 pc set but for a few years it was 12 pc set. 4mm to 14mm set also has 5.5mm (all new condition)
5 pc tamper proof Torx set. (new)
Pocket Phillips and flat head screwdrivers with clip (new) phillips was really hard to find.
T-6 T-7 Torx I have the only two I ever seen. Didn't know they made them. Til I found them on eBay. There is a T-9 but don't have one yet.
I'm sure there's more. And some of them you can find easy but it was hard to find a cheap price.
