Hugo Köller Solingen folding knife set, comprising two vintage examples including a distinctive hawkbill pruning knife and a slimmer straight-blade utility knife. Crafted in Solingen, Germany—renowned for its blade-making heritage—each piece features steel blades with visible maker’s marks, one stamped “No. 211 12 cm,” and traditional pinned handles: one in rich dark wood, the other in striking red composition. The curved blade form is characteristic of horticultural and grafting use, prized for precision cutting, while the companion knife offers versatile everyday utility. Both show honest age-related wear, light patina, and surface marks consistent with use, enhancing their authentic character.
