Item Name: Blow More Glass Tools - Scoring Knife SKU: ABR-BMGT-854-300 Description: This scoring knife is a handheld glass cutting tool built around a small, hardened scoring wheel mounted in the head of the knife. It is designed to make a clean, controlled score line so glass can be broken accurately with minimal chipping and less edge cleanup. In lampworking and scientific glassblowing, a scoring knife is used any time you need a precise break on tubing or rod before moving to flame work, such as cutting sections for seals, trimming blowtubes, sizing stock for joints and transitions, or preparing straight cuts that will be fire-polished. A dedicated scoring knife is also useful at the bench because it is quick to grab, easy to control, and consistent for repeat work. How it is used: Place the glass on a stable surface or support it securely in your hands. Set the scoring wheel where you want the cut and make one firm, continuous score while rotating the tube or rod smoothly to keep the line even. After scoring, snap the glass using controlled pressure or use a gentle thermal technique at the score line to start the break, then dress the edge or flame-polish to finish. Show more
