The 19-Tool Industrial Arsenal

Pro Tip & Super Tool® 300 Maintenance: Because the Super Tool® 300 is designed for punishing jobs, keeping its internal hinges clear of grit, mud, and metal filings ensures perfect execution. Flush out the handle scales with a mild solvent or warm water if exposed to field grime, dry thoroughly, and apply a high-viscosity tool lubricant to the plier joints and locking springs. Periodically check the retention screws on your 154CM wire cutters to ensure they are seated tightly; keeping these cutters perfectly aligned prevents premature wear and allows you to snip through tough fencing, wire bundles, and hard cables cleanly for decades to come!
