The Zwilling Self-Sharpening Knife Block is a storage solution that keeps your knives sharp with minimal effort. Each slot has built-in sharpening wheels that hone the blade every time you slide a knife in or out, so you always have a ready edge. This guide covers what comes in the block, how the sharpening system works, and how to care for it so your knives stay in top condition for years.
Ingredients
- 1 Zwilling Self-Sharpening Knife Block (with knives, if purchased as a set)
- 1 soft, dry cloth (for wiping blades before storage)
- 1 drop of mild dish soap (optional, for cleaning the block exterior)
- 1 small brush (e.g., a clean toothbrush) for cleaning the sharpening slots
- 1 food-safe mineral oil (for wooden block models, if applicable)
Instructions
- Unpack and inspect. Remove the block and knives from the packaging. Check that all slots are clear of debris and that the sharpening wheels (the small ceramic or tungsten discs inside each slot) are intact and turn freely.
- Wipe the knives. Before first use, wash each knife by hand with warm water and mild soap, then dry thoroughly with a soft cloth. This removes any manufacturing oils or dust.
- Insert each knife into its designated slot. Match the blade size to the slot: the largest slot is for the chef’s knife, the medium for the utility or carving knife, and the smallest for the paring knife. Slide the blade all the way down until the handle rests on the block.
- Sharpen by removing and inserting. To sharpen, simply pull the knife out of the slot and push it back in 3–4 times. The sharpening wheels will hone the edge. Do this every few uses to maintain the edge.
- Clean the block monthly. Unplug or remove all knives. Use a dry brush to sweep out any metal filings or food particles from the slots. Wipe the exterior with a damp cloth and mild soap if needed, then dry immediately. For wooden models, apply a thin layer of food-safe mineral oil every 3–6 months to prevent drying.
- Reinsert knives after cleaning. Ensure the slots are completely dry before putting knives back in to prevent rust or bacteria.
Tips
- Use the right slot. Forcing a large knife into a small slot can damage the blade and the sharpening wheels. Always match the knife to the slot size.
- Hand wash only. Never put the knives or the block in the dishwasher. The heat and moisture can warp the block and dull the blades.
- Don’t over-sharpen. The self-sharpening system is designed for maintenance, not heavy sharpening. If your knives become very dull, use a honing steel or a whetstone first, then use the block to keep the edge.
- Keep it dry. Moisture can cause rust on the blades and mildew in the slots. Always dry knives completely before inserting them.
Serving Suggestions
This knife block is a kitchen tool, so “serving� means using it to keep your knives ready for any task. Pair it with a cutting board, a honing steel, and a good set of kitchen shears. It works well on a countertop near your prep area, or inside a cabinet if you prefer a clutter-free look.
Variations
Zwilling offers several versions of the self-sharpening block: some come with a full knife set (e.g., chef’s, bread, utility, paring), while others are sold as a standalone block that fits your existing Zwilling knives. There are also models with a bamboo or acacia wood exterior, and some with a built-in honing steel at the side. If you have a different brand of knives, check the slot sizes—most standard Western knives will fit, but Japanese knives with a different bolster may not.
Storage and Reheating
Store the knife block on a dry, stable surface away from the sink and stove to avoid moisture and heat. The block itself does not require refrigeration. Knives stored in the block should be used within a few days of sharpening; if you don’t use them for weeks, the edge will still be fine but may benefit from a quick pass through the slot before use. There is no reheating involved—this is a storage tool, not a food item.
Frequently Asked Questions
How often should I use the self-sharpening slots? For regular home cooks, pulling each knife through the slot 3–4 times once a week is enough to maintain a sharp edge. If you cook heavily, you can do it daily, but avoid excessive passes as it can wear the blade faster.
Can I sharpen serrated knives in this block? No. The sharpening wheels are designed for straight-edged knives. Serrated knives should be sharpened with a ceramic rod or professionally. Using the block on a serrated blade can damage both the blade and the wheels.
Will the block fit my existing knives? Most Zwilling knives and many other Western-style knives with a blade length up to 8–10 inches will fit. However, knives with a thick bolster or a very wide blade may not slide in properly. Measure your knife’s blade width and compare it to the slot opening before purchasing.
How do I clean the sharpening wheels? Over time, metal filings can accumulate on the wheels. Use a dry toothbrush to gently brush the wheels inside the slot. You can also use a can of compressed air to blow out debris. Do not use water or oil on the wheels, as it can attract more dust and reduce effectiveness.
Is the block safe for children? The block itself is heavy and has sharp knives inside. Keep it out of reach of young children. Some models have a locking mechanism, but always treat it as a potential hazard.
What if my knives become dull despite using the block? The self-sharpening system maintains an edge but cannot restore a very dull or damaged blade. Use a whetstone or take your knives to a professional sharpener. After sharpening, the block will help maintain the new edge.
