Hey Nutty,
My views as a newbie to weed (old hand grower of veg etc) I've used these u shaped bonsai snips to great effect. As for the brand Fiskars - you can't go wrong, they also make fantastic axes.

Mine u shaped scissors do not have a hinge at the back and made of plastic so they are cheap and easy to use. The blades are sprung steel and are as sharp as a razor. I use normal secateurs to cut up the big branches and stems but trim with these little guys.
What I'd really like are some real Japanese bonsai scissors. Apparently the shape is to reduce stress when cutting, and the long handles that curve back on themselves "ding" with each snip. Zen or what? I can't afford a handmade pair $35,000 so a Chinese knockoff will have to do.
