Subject: Designing arthritis friendly secateurs / pruners! Input appreciated
I am a university design student who has been set the task of designing a pair of ergonomic secateurs (pruning shears). I thought what better opportunity to cater to those suffering from all types of Arthritis!
My own knowledge of Arthritis is limited, so I have some questions for anyone who suffers, and any form of input is much appreciated ;)
1. What are your issues with arthritis that affect your hands?
2. Do current secateur designs stop you from using them?
3. If so, is this because:
A. The handle diameter is too big
B. the handle diameter is too small
C. The handles require too great range of motion D. The handles require too much pressure
4. What kind of secateurs do you use most often? A. Cheap
B. Ergonomically designed
D. Rolling handle
