Bread-Bakers v109.n006.6

OK.  I have now made many good loaves of bread and my family is so 
happy!  I have just one more hurdle to over come to stop buying so 
much bread at the store.  Does anyone know of something to help me 
cut the bread straight?  The kids like sandwiches and I am always 
cutting the bread too fat at one end or too thin at the other.  Any 
suggestions would be great!
