Not just pocket clips -- although why you wouldn't want to be able to adjust those is puzzling.
Buck Vantages (large and small) and Kershaw Sapphire, to name just a few folders from my top drawer alone.
And then there's all those pesky T6 screws holding on your scales.
The T6 is a necessary size for pocket knife owners who want a complete set of tools.
Gorilla, Eklind and BM recognize that -- Wiha, unfortunately, does not, in its not-quite all-in-one folding set.
Who said anything about not being able to adjust T6? The set I have starts at T5. They have a variety of different sets.
