{"product_id":"diamond-sharpening-plate","title":"Diamond sharpening plate, 170 x 75 mm","description":"\u003cp\u003eA blunt tool is not just slower. It pushes instead of cutting, and pushing is what tears a workpiece, snaps a small drill and puts your hand where it should not be.\u003c\/p\u003e\n\u003cp\u003eDiamond grit bonded to a steel plate, 170 x 75 mm, on a non-slip base.\u003c\/p\u003e\n\u003ch3\u003eDiamond, not stone\u003c\/h3\u003e\n\u003cp\u003eA water stone wears into a hollow, and once it is hollow every edge you sharpen on it comes out convex. Diamond plate stays flat because the abrasive is harder than anything you will put on it - it does not dish, it does not need flattening, and it cuts carbide, which no natural stone will touch.\u003c\/p\u003e\n\u003cp\u003eIt also cuts dry. A drop of water keeps swarf clear, but there is no soaking and no slurry.\u003c\/p\u003e\n\u003ch3\u003eThe grits\u003c\/h3\u003e\n\u003cp\u003e400 reshapes - a chipped edge, a burr, a bevel that is the wrong angle. 1000 sharpens; this is the one that does the actual work on a tool that is merely dull. 3000 polishes the edge so it stops grabbing.\u003c\/p\u003e\n\u003cp\u003eMost bench work only needs 1000. Buy all four if you are restoring old tools rather than maintaining sharp ones.\u003c\/p\u003e\n\u003ch3\u003eWhere it stops\u003c\/h3\u003e\n\u003cp\u003eA new diamond plate cuts fast and coarse for the first few uses because the proudest grit particles break away. That is normal and it settles.\u003c\/p\u003e\n\u003cp\u003ePress lightly. Diamond cuts by scratching, and leaning on it tears grit out of the bond - that is how a plate goes bald in a month. Let the abrasive do it.\u003c\/p\u003e\n\u003cp\u003eFlat things only. A plate sharpens chisels, blades, plane irons and flat-ground edges. It will not sharpen the inside of a gouge or the flutes of a drill bit.\u003c\/p\u003e\n\u003cp\u003eThe seller lists food-contact and EU conformity marks. Those are their claims, not our testing.\u003c\/p\u003e","brand":"Mikrabench","offers":[{"title":"400","offer_id":47513173688511,"sku":null,"price":19.99,"currency_code":"USD","in_stock":true},{"title":"1000","offer_id":47513173983423,"sku":null,"price":19.99,"currency_code":"USD","in_stock":true},{"title":"3000","offer_id":47513174016191,"sku":null,"price":19.99,"currency_code":"USD","in_stock":true},{"title":"Set of four","offer_id":47513174048959,"sku":null,"price":69.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/5826\/3743\/files\/S1c7e3b6a0b3f466aa144fc3dc4a107e4m.webp?v=1789880313","url":"https:\/\/arvonelle.com\/products\/diamond-sharpening-plate","provider":"ARVONELLE","version":"1.0","type":"link"}
