knifesturbator 

One who sits around all day... playing with a knife. Opening, closing over and over! Repeatedly. Click. Click. Click.

Soupy sits around all damn day flicking his Sebenza, the KNIFESTURBATOR! If only he would get a job he would help the world's problems!

knifesturbate 

To fondle a knife and play with it when you have more important things to be doing.

I could knifesturbate for hours with my new Swiss Army Knife. It has so many things in it!
