For this comparison, I compared 4 nippers, as well as the classic control of just snapping it apart with your hands.
The four nippers I compared are :
Princess Auto wire cutters
Standard cheap nippers
God Hand SPN-120
First up, God Hand vs Breaking the runner by hand
(Left Godhand, right myhand)
Easy to see god hands win this one. But really anything would
Or would it?
Here is Godhand (left) vs Princess auto wire cutters (right)
Possibly worse than breaking them by hand. They really are not meant for fine cutting.
Next up Godhand (left) vs Cheap Hobby nippers (right)
Slightly better than the last ones. Still not great. But this is $5 vs ~$80
Finally the main event. Godhand (left) vs Wave nippers (right)
This is the real test, and honestly these produce a very similar cut.
My only note on them is the godhands are a little easier to cut with. But seem to produce a similar result.
So in conclusion, the godhands cut nicer than the competition, but not a whole lot better. It's up to the user just how fine a cut they want, and how much they want to pay for it. I put together a few parts of my PG Exia using the godhands, and didn't notice a big difference in the left behind stress marks, or nub marks. A good xacto blade would make more of an impact at that point.
The godhands get a ton of hype, as do the gundam planet nippers. Both are fairly expensive in Canada at least. If I had to get a new pair, I would probably get another pair of the Wave nippers, or possibly some of the Mr Nipper GX nippers. Mr hobby makes pretty good products.
