Knipex has some great sidecutters.
The only other single bladed nipper I've used is the USA Gundam Store brand, which is manufactured by Simp if I'm reading the label correctly. It cuts clean, but not flush. There's always like 1mm of nub left. Not sure if they're all like that or I just got a bad pair, but if I have to do nub cleanup anyway I might as well just use a cheapie set of nippers.
FWIW I'm still on my first SPN-120 nipper. They're about 5 years old, and between my fiancé and I, I don't even know how many kits that is. They started to feel not quite as sharp about a year ago, so I grabbed the USAGS ones because cheaper and free shipping. After testing them out, I bought a backup set of Godhands in case my original gets dropped or otherwise damaged.
Not a single bladed nipper, but still surprisingly useful, is the Mr. Easy Nipper. Yes, the one that looks like nail clippers. They are my go-to for nubs that Bandai decided to put on inside arcs or otherwise hard to reach places.
I got the Dispiae ST-X single blade nipper and I really like it. Never used God hands before, but comparisons seem similar for half the price.
I've got a pair of stedi's and God hands. The stedi's are half the price and seen to be giving the GH a run for it's money
My first single bladed nippers were from USA Gundam Store. After those broke, I found a pair from SIMP at a convention. They're both really good and only about $35 USD.
