I have a Utica melon tester somewhere that I recieved "free" from a seed company, shipped to me with my seed order. Unfortunately I'm not sure where it is! It will turn up someday.
I think of melon testers as having a single blade and being at least 5 inches closed length. Here's a couple that have multiple blades and are 4-1/4 inches long. Case called the 6296X a "citrus knife". I have no idea about the York whittler, except the shape and length appear to be appropriate for the same useage.
