Tru-maxx 05139050M Fine Rectangle Sharpening Stone

Product Description

The TRU-MAXX 05139050M is a fine-grade rectangular sharpening stone used to hone and sharpen cutting edges on hand tools, blades, and shop equipment. At 0.5 inches thick, this stone delivers controlled abrasive contact suited for finishing and edge refinement rather than heavy stock removal. Fine-grade stones are the standard choice when restoring a sharp working edge on chisels, plane irons, knives, and similar tools. Machinists, maintenance technicians, and skilled tradespeople keep stones like this at the bench for routine tool upkeep between more aggressive grinding operations.

This sharpening stone is suited for bench use in machine shops, maintenance facilities, and trade workshops. Its rectangular profile allows flat, consistent strokes across a blade edge, making it practical for freehand sharpening of flat-ground tools. The fine grit is appropriate as a finishing step after coarser stock removal, or as a standalone tool for lightly dulled edges that do not require re-profiling.

Installation Notes

No installation is required for this sharpening stone. Secure the stone on a flat, stable surface or in a dedicated stone holder before use to prevent movement during sharpening strokes. A honing oil or water lubricant is typically applied to the stone surface to float away metal swarf and extend stone life. Keep the stone clean and stored dry when not in use to prevent contamination of the abrasive surface.
