Spyderco fixed blades at around $100 or under.
Ark is going to be to small.
The Swick would work with the finger hole.
The Reverse is just not a good EDC, but would be ok if you like the blade shape.
The Moran has a good grip but. I’m starting to get a bit of arthritis too and what worries me is that if I have a loose grip. There isn’t much to stop my hand from going forward on to the blade with the Moran
The Streetbeat and the Enuff would my best picks. Even with loose grip, they feel secure in the hand. With the Enuff you have a pick of different blade styles. Small knife with full grip and enough blade to do the job.
If you want a bigger blade? The Street Bowie and the Aqua Salt would service you well.
Opps! Forgot about the Ronin 2, a lot of blade, not much handle. The others offer a better grip.
