I know there were many other similar models with rubber or rubberized grips, but I’m mainly referring to the more unique ones. With that said, did any other manufacturers have whacky grip designs similar to these?
BTW – if you have one of these you want to sell, please let me know!
I think there was another Pentel ‘ergonomic experiment’… the Shift Grip or something? They also made the Flex Grip series that allowed some chonky clear grips to be twisted left/right.
I think you are referring to the FlexFit and FlexFit II which had silicone grips that you could twist one way or the other to create a spiraling finger-groove grip.
The A335 Shift.A.Grip is probably what you are thinking of. I don’t know much about it, so not much in the Pentel Book.
I do have the FlexFit & FlexFit II, due to the double knock mechanism, and as Dave says, the grip can be twisted to provide a more custom grip for either right or left handed people.
