Overview
These are vintage Melon Testers with advertisements on them. Two are made by Colonial Knife Company and the third by Gerson Co Boston.
They all have polished and fully serrated blades with nail nicks. The handles have composite (bakelite?) scales, brass liners and stainless springs. One has double bolsters, one single bolsters (Gerson Co), and the third has no bolsters. They have some light scratches, but overall good condition for their age.
