Brand-new etching needles have rather sharp points that create blunt lines. Some of these tools feature diamond-shaped tips and wooden handles. Other etching needles have carbide tips, which you can sharpen as needed.
A burin is an essential metal engraving tool. It creates clean lines while forming a V-shaped groove in metal. The tool has a long shaft that makes it easy to work with. Etching lines into a metal plate with a burin creates lines that have tapered ends.
A burnisher is a handy error-correcting tool. If you scratch a line in the wrong place on a sheet of metal, you can use this tool to smooth the metal’s surface. Use of a burnisher prevents ink from depositing into areas where you don’t want it. It’s also a great tool for evening out unsightly pits and flaws within a piece of metal before dipping the plate into an etching solution.
