Knives? no, not yet. Glue? yes. when i first started buying modles i used, not the right glue, but industrial strength modeling glue. It literaly melted parts of the Necron Destroyer i was trying to make. And it kept falling apart. It smelled nasty too. That poor miss-shapen thing is now in some cabnet never to be seen again(cept for the rats, they see everything
) When i got smart and bought the real glue for these kinds of figures i was also prompted to buy the un-stick stuff for the gule. I am so happy i got that. Some guy told me about how he guled his hands together wiht some real gule and ripped skin off trying to un-stick it. oi!
