Help for arthritic knitter

I’ve been knitting for a few years, but took up circular needles recently so that I can do colorwork. My right hand has a bit of arthritis, making normal circular needles difficult to hold as the wooden or metal grips are just a bit too short. If I could find a source for needles with grips about 1/2 to 1 inch longer than usual, it would help so much. Most packages don’t give the length of the grips, just the over all length. Any help will be most appreciated.

How long do you want the needle parts to be? And what size?

Thank you for replying. I am currently using needles with 3.75 wooden grips. 4.0 to 4.75 grips (or longer) would be excellent. As to size, I mostly use sizes 6.0mm to 9.0mm, with length of 16" tip to tip, but 18" or 20" length would be even better. I have tried metal needles, but wood or bamboo seem to be better for my hand.

How about Addi Lace? The needles themselves are a bit more than 12.5 cm. They are found in most dimensions and lengths:
They are metal, thou…

Thanks for your help. I’ll check it out.
