I have a Rogers pipe knife that now has a floppy (not side-to-side) blade after falling from the table to the floor of the kitchen. The spring for the blade broke in half and the blade just flops around, it will open if you flick the body of the knife. Once open there's no tension to hold it in place it can be flicked back to closed. When closed it goes too far so that the nail mark for your fingernail to open the knife is buried behind the bolster. Is this an easy and inexpensive fix? It doesn't have a lot of sentimental value so it's not a repair at any cost situation. Recommended knife repairers are also appreciated.
