You don't need to guess. Hold the guide against the stone and pull the blade toward you — that's the entire technique. Most people get a noticeably sharper knife on their first attempt.\u003c\/p\u003e\n\u003ch3\u003eWhich side do I use first?\u003c\/h3\u003e\n\u003cp\u003eAlways start with the 400 grit (coarse side). This rebuilds and resharpens the edge. Then flip to the 1000 grit (fine side) to polish it to razor sharp. For a knife that's only slightly dull, you can skip straight to 400.\u003c\/p\u003e\n\u003ch3\u003eDoes it work on Damascus and Japanese knives?\u003c\/h3\u003e\n\u003cp\u003eYes. This stone works on all high-carbon steel, stainless steel, and Damascus steel kitchen knives. For Japanese knives sharpened to 15°, use the angle guide set to 15°. For Western-style knives (typically 20°), use the 20° setting.\u003c\/p\u003e\n\u003ch3\u003eHow often should I sharpen?\u003c\/h3\u003e\n\u003cp\u003eFor home cooks using knives daily: once every 2–3 months with this stone. Between sharpenings, a honing rod or leather strop keeps the edge aligned. A sharp knife that's well-maintained with occasional sharpening will outlast a knife that's never touched.\u003c\/p\u003e\n\u003ch3\u003eDo I need water or oil?\u003c\/h3\u003e\n\u003cp\u003eWater only. Soak the stone in water for 5–10 minutes before use. The water creates a slurry that helps the stone cut efficiently and prevents the stone from glazing over. Never use oil on this stone.\u003c\/p\u003e\n\u003ch3\u003eHow long does it take?\u003c\/h3\u003e\n\u003cp\u003e10–15 minutes per knife for a full sharpen. Once you're practiced, 5 minutes is realistic for a maintenance sharpen on the 400 side only.\u003c\/p\u003e\n\u003ch3\u003eIs the bamboo base stable?\u003c\/h3\u003e\n\u003cp\u003eYes. The non-slip rubber feet on the base keep it fixed on any countertop surface. The stone sits in a recessed groove in the base — it won't slide while you're sharpening.\u003c\/p\u003e\n\u003ch3\u003eDoes it come with instructions?\u003c\/h3\u003e\n\u003cp\u003eYes — a quick-start card is included with every order. The angle guide is also self-explanatory — it clips onto the blade and the number markings show the angle.\u003c\/p\u003e","brand":"Rational Steel","offers":[{"title":"Default Title","offer_id":53266431541514,"sku":"RS-ACC-001","price":44.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/7522\/9194\/files\/acc2.png?v=1782539584","url":"https:\/\/rationalsteel.com\/products\/whetstone-knife-sharpening-stone","provider":"Rational Steel","version":"1.0","type":"link"}
