This handy tool securely holds round (up to 7mm dia.) and square stamps (up to 7/32"W), including your homemade stamps, while keeping fingers at a safe distance from the hammer strike. Simply insert the stamp into the round hole and tighten by turning the knurled handle—it's that easy. It also makes lining up the stamp a snap because there's nothing to obscure your view of the stamping surface.
