Stupid thing I do often and never learnt not to do. Place exacto knife in right hand, balsa in left hand, thumb or other finger over cutting area, say to your self, Watch the knife will suddenly come through the balsa and I will cut myself, ignore self and continue cutting. What happens? Knife slices cleanly thourgh balsa into finger. And now I know the true Use of CA. LOL[img]i/expressions/face-icon-small-blush.gif[/img]
