Hmm- will give this a try - thanks for the effort, had trouble with all the others - hopefully this is better. Just 1 thing, like w1zd00m said
- many people use middle mouse for knife - THE PERFECT KEY would be an un-used keyboard key ( so you could keybind to right mouse)
or the RIGHT MOUSE BUTTON itself, but nevermind that 4 now, many thanks- going to try now
