Elevate your WORK SHARP Precision Adjust Knife Sharpener with the Upgrade Kit, a thoughtfully designed bundle that expands edge possibilities without replacing your existing setup. This kit brings together seven abrasive options, plus a molded carry case, so you can experiment with bevels, transitions, and polish levels to suit different blades and tasks. Important: the Precision Adjust Sharpening Base is not included in this kit, so you’ll want to pair it with your current base if you have one.

What’s inside and how it helps your sharpening routine

• Seven abrasive grits cover the journey from material removal to final refinement: 220, 320, 400, 600, and 800 diamond grits, plus fine ceramic. These options give you control over edge shape and aggressiveness, enabling you to reprofile dull blades or create a smooth, polished edge on your favorites.
• Leather strop provides a final touch for edge refinement, helping you reduce burrs and achieve a clean cut with less effort.
• Small ceramic rod for serrations offers a dedicated path to address serrated knife teeth, helping you maintain even bite along the serrations where it matters most.
• Molded carry case keeps the new abrasives and your original sharpening base organized in one place, making it easier to transport or store when not in use.

Create custom edges, explore multiple finishes

The combination of grits lets you tailor your edge with intention. Start with the coarser diamond grits to reprofile and set the bevel on an older blade, then progress through the finer options to sculpt a precise edge geometry. For knives you use daily, the finer diamonds and ceramic stages can help you achieve a balance of sharpness and durability that suits your cutting tasks without being overly aggressive.

The kit is designed to be versatile, so you can experiment with different edge profiles across a range of blades—from kitchen knives to utility tools. While results depend on technique and blade condition, the available grits provide a practical path to improved performance compared to a single-step approach.

Sharpen serrated knives with confidence

The included small ceramic rod is specifically mentioned for serrations, giving you a focused option to refresh the teeth on serrated blades. This can help maintain even contact along the edge where performance matters for slicing and saw-like cuts.

Portable, organized, ready to travel

The molded carry case is designed to keep everything in one place, so you can take your sharpening routine on the road, to a workshop, or to your outdoor setup. Organization matters when you’re juggling multiple blades and tasks, and a compact case helps you stay efficient while preserving your tools.

Notes for buyers

• The Precision Adjust Sharpening Base is not included in this Upgrade Kit, so you’ll want to pair it with your existing setup if you own one.
• This kit emphasizes flexibility and edge customization rather than guaranteeing a specific outcome; results will vary with blade condition, technique, and maintenance.
