Just wanted to say that while I would generally agree that a good knife is the better choice for most people, not everyone is able to use or properly hold a knife. I've seen videos of folks who make recipe videos using tools like this to help overcome physical disabilities. Elderly people can benefit as well due to conditions like arthritis or just a concern about using a sharp knife. We've all got an image in our minds of who the average BIFL poster is but we should take a few moments to consider the circumstances of people who may not be exactly like ourselves.

Hope you have a wonderful wedding!
