Last I checked I had enough hand strength and manual dexterity to hold a cyllindrical object in my hand (weapon hilt?) and still use a finger or two to work an object held in the other hand. You don't need both hands open unless you don't have thumbs. Disclamor: However, this is my personal experience, and your milage may vary.

Edit: It occurs to me that I might need to point out that I was referring to weapons, and not other cyllindrical objects... and it amuses me to have to point that out.
