I'm trying to envision a creature that is highly dexterous, and adept at using tools, but every time I try to think of a possible grasping appendage, the only two I come up with are either tentacle like appendages (cephalopods) or jointed digits (humans).

I want to create a sentient life form with neither tentacles or digits, but the closest thing I could think of is an inflatable appendage that can envelop objects, and I don't think that would be good for tool usage.
