Well it does come in three attractive shades, and it does have a nice spring

It has a spring on the bolt to pop the clamp away from the clamped whatever as soon as you've loosened the screw enough. The standard clamp requires you to not only unscrew the bolt, but also manually pull the clamp out to free it. It's a convenience feature. Possibly a cheap DIY mod if you can find springs of the right size and compressibility.

Seems like a neat trick! I sometimes nick the paint if I open and close too quickly so this would eliminate that effect!

The clamp is also slightly longer on one side. So as you unscrew it, the spring pushes the clamp out, and the slightly longer side keeps the clamp oriented. It doesn't rotate around, so it leads to a much cleaner, faster clamp/unclamp method. Nice!

Unfortunately the company is only selling to the domestic market at this point, not internationally.

dremel+big spring=same effect. They should license it to BromptonProper. Like I should with my stem QR hack...

My question is how do the Thai-made (?) alternative titanium hinge clamps compare to the aluminum ones sold in Japan? And, on the face of it, I agree with the earlier poster - why not just add a spring to the current originals, whether real Brompton or knock- off. I am both fascinated and disgusted by the concept. How Romanian dictator - gold-plated toilets next!
Where do I buy Kamoya ones in Tokyo?

Been looking at these on eBay. Looks like the newest twist on these is that on the side of the clamp that is longer, they've imbedded a neodymium magnet so that the longer end sticks to the frame. I'm actually tempted to try it out, but $85+ is a steep price for admission.

Has any one tried these Bike Gang They look to be a less expensive alternative but I can see the case for light springs.
so many possibilities...
notice how, in the ridea knob, the left side is smaller and both sides are more ergonomic than in previous solutions we've seen. i suspect the next iteration will be the obvious, single-sided twiddle-knob.
design development takes time, even when the "ultimate solution" seems self-evident and obvious.
*frog life cycle development graphic intended as a humorous graphic parallel only. no disparagement of frogs or their life cycle was intended.

I think this is the first time I've seen "frog" and "Brompton" in the same thread. Impressive.

I find it useful to have my thumb across the handle to snug the 'pac-man' down properly..
kitchen faucet is another story..

It may not sound like a lot, but the weight savings (minimal) and more importantly, the fact that the clamp stays aligned after unfolding really makes a big difference to the predictability of the fold. Plus, the look - shiny brass handle with black contrast clamp - is fantastic IMO.
