Once you have cured your bacon and smoked it if you wish, you will need to slice it!
You can do this by hand with a good knife and a steady hand, but if you are going to be doing it regularly it might be worth investing in an electric slicer.
There are various models to suit all budgets and they can often be bought second hand. The one you see in the first picture is a small, domestic unit but more than suitable for relatively small amounts. In picture two, you can see a medium sized ‘commercial’ slicer, the like of which you would find in a deli shop.
If you find yourself making larger amounts of bacon, ham, other cured meats or using it for slicing the leftovers from Sunday Lunch you might need to consider a ‘better’ model. Look out for them on Ebay and other auction sites.
