Ive got ya beat by one year!
At 81, I have some definite arthritis from half a lifetime in a machine shop cranking on Bridgeport mills and Hardinge lathes. Some bad worn and painful knuckles. BUT...I can and do carry the old Wenger SI, pioneer, cadet, and alox bantam on a regular basis. I love the alox models and I really believe them to be the better quality SAK's. Yes, they are built a bit beefier, but they will hold up to hard work better than the cellidor models. I've had a tinker buckle at the middle rivet because the Phillips driver is not as sturdy as it needs to be, and I've had cellidor scales melt from some gun cleaning solvents an mosquito repellents.
If you can't handle alox SAK's without fear of cutting yourself, maybe you'd best not handle any pocket knife. My Wenger SI is over thirty years old, has seen some very hard use, and aside from the blade being a bit worn down, and the screw drivers a bit scarred, its fit for carry today. As I type, its in its nylon belt pouch, along with a Fenix E01. I've actually held it by the open screw driver/bottle opener and used the handles as a small tack hammer.
The alox SAK's are the bomb proof
