Hozan C-205 Lockring Tool
The Hozan Lockring tool is made of chromed steel, but when it comes to removing or installing lockrings, it's worth it's weight in gold. Quality forged steel is super hard so the hook ends will not round off causing steel and soft alloy lockrings to round off on the edges.
The double ended hooks are different diameters and will fit almost any size lockring. This tool has been around shops for ages and will be the last lockring tool you will ever buy.
