With any camera, you'll get a sharper image by using a tripod, but some kinds of shots just can't be gotten easily with a tripod, and if a tripod causes you to leave the camera at home, then you can't shoot anything.
These are handheld with flash, Weegee-style, so that's one approach--

These were shots that should have been taken with a tripod, but I was just casually walking around with the Technika without being particularly on a photographic expedition, and if I had to carry a tripod, the camera would have stayed at home--
Handheld with 6x7 back--
Also, remember the rangefinder is still useful with a tripod for portraits or any kind of action where you want to focus and have film in the back at the same time.
I've even done a little impromptu bird photography (large, relatively approachable birds) with a cammed 360/5.5 Tele-Xenar and rollfilm back. The limiting factor there is the slow max shutter speed, but if you're shooting something like herons or waterfowl, they can hold still.
