The ARS SD-95-PN is a compact 3-sided diamond sharpener designed for maintaining pruning tool blades and knives. Featuring a retractable pen-style design, this sharpening tool offers exceptional portability for gardeners and horticultural professionals who need to keep their cutting tools in optimal condition whilst working.
