Sorry to hear about your mishap.I work in the building trade although i am management and dont do any real work well thats according to the tradesman.One of the guys was sawing some timber in the garden when the lady of the house comes out and asked if he wanted a cup of tea.He turns round to say "yes please"and continues sawing and the same time straight through the top of his hand.Good job it wasent a bacon buttie he would have taken his hand off.
