A karambit model printed for selfdefene training purposes.

this is printed in ABS, then painted in black.
I'll try also a Flexible PLA version that could be safer to use.

After publish I make a search and found that a similar one already exist in thingiverse, probably we use the same source for it.
Mine is completely modeled starting from scratch, anyway the thing is http://www.thingiverse.com/thing:149985
