I do some 'hobby' bookbinding and cutting card and paper accurately is a must. A common requirement is to "square up" the paper part book edges once they are assembled and before you put them into whatever cover you are making, for this you need something that can cut through 200-300 pages cleanly, this can do that well. This is a well made and heavy bit of kit, the delivery driver wasn't that amused with carrying it up my drive !If I needed something for a commercial use where I would be using it quite a number of times a day every day in a business, it would not be the right tool, I would need to spend a lot more money than this cost for that level of use. What makes this such good value for a hobbyist such as myself is that it is very robust and when you look at the price of simple guillotines that would only be good for paper and struggle with more than one sheet of card, its a real bargin.
