Trust me anon... it's rock solid. I don't have to use any grip stength at all... none... the grabber does the gripping with spring tension (see the way the back of the handle clips together... and see how far appart the ends are when unclipped... spring tension). I've held a full can of water with that thing (more than 2 cups) and bounced the can up and down... swung it to and fro... poured it out... filled it from the tap at full pressure... whatever... it doesn't budge at all... i cannot get it to fail... it's clamped on there tight as a vice... really. So far, I'd say it's far better than the other options I've tried... in terms of both function and safety. And I've tested it with hot water too.
As for nothing new... it's new to me... and I'm having fun "freaking out", experimenting, inventing and learning from others.
I might add, there are a lot of homemade alcohol and esbit solutions out there... but I don't see many complete kits (lid, pot, stand, windscreen, handle, stove/esbit holder) for 65 grams. This is just an experiement for me to see how light I can make a complete and very functional kit... and it's a lot of fun... in a weird, geeky inventor kind of way :P
Anyway, I'll stop posting for now until the design is completely finished and trail tested... probably in a week or so.
