Tetrahedron

Another one from Vinco’s new batch. It’s quite tricky to see any seems in this puzzle, and quite hard to feel them too. I got really confused even on to where to start on this one because there is no way of getting any kind of grip.

This is one of Vinco’s new designs. Even though I’m starting to get a pretty good feel for his puzzles, I ran into some problems getting this puppy open. =)

Sat down in my sofa and started to fiddle with this one while I was glancing at the Tv, didn’t really get anywhere, but I kept going and then all of a sudden it open! Spooked me quite a bit, because all of a sudden I had this thing that was semi-open and quite a lot bigger then I started =)

Also requires a little “multi-fingery-movement” and shares characteristics with Flattrick and Explosion Cube, but has it’s very own “take” on it.

About the same size as Flattrick and displays very nicely.
(Had some problems taking pictures of this one, the picture makes it look a bit crocked and rough, but it’s the exact opposite… straight and smooth)
