Newbie looking for disability aids!

Hi @Daisybelle - Welcome to the community. I have difficulty with this too, & have found that with many you need to have one good hand to hold the jar in order to use some. I've used the following shop before. I find them reasonably priced (you can get VAT relief), & they have some examples that look like they'd work for you. Please see: https://www.completecareshop.co.uk/kitchen-aids/bottle-and-jar-openers/

Hope this helps.
