If you like ease of use and don't like fighting with a tool to get it to work, don't buy this knife. We could not get the blade in place. I even tried again today before I went online to do the return. No luck. It's not even worth the 1 star I gave it. Don't waste your money.
According to the packaging you are supposed to be able to change blades on these knives with a push of a button. However, there are no instructions and after several attempts I gave up and opened it with a screwdriver. I would not purchase this product again.
