{"product_id":"holdfast-rolling-knife-sharpener","title":"Rollkeen Rolling Knife Sharpener — 400 Grit Diamond + 3000 Grit Ceramic, 15° \/ 20° Magnetic Angle Block","description":"\u003cp dir=\"ltr\"\u003eA magnet holds the blade at 15° or 20°. You just roll. It takes the guesswork out.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIT WAS NEVER YOUR HANDS\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAlmost nobody fails at sharpening because they lack talent. They fail because holding a blade at one constant angle for two minutes, freehand, is genuinely hard — and the moment the angle wanders, the edge stops forming. Take the angle away from the person and what is left is easy.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThat is the whole idea. The angled block holds the knife. You roll the cylinder. The bevel comes out the same every pass because it is the block setting it, not your wrist.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTWO GRITS. BOTH ON THE ROLLER.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eMost rolling sharpeners ship with one grit and sell you the second one later. Rollkeen has both, one on each end of the roller:\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e400 grit — resets a dull edge, the one that has been living in the drawer for three years\u003cbr\u003e3000 grit — polishes it down to a clean, razor-sharp finish\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTurn the roller over to change grit. Nothing to swap, no tools, and nothing else to buy.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eHOW IT WORKS\u003c\/p\u003e\n\u003col dir=\"ltr\"\u003e\n\u003cli\u003ePick your angle. 20° for German and most Western knives. 15° for Japanese and anything ground thin.\u003c\/li\u003e\n\u003cli\u003eSet the blade flat against the angled face. The magnet pulls it square and holds it there.\u003c\/li\u003e\n\u003cli\u003eRoll the cylinder down the edge, heel toward tip, light pressure. Start on the 400 grit end if the knife is properly dull.\u003c\/li\u003e\n\u003cli\u003eFlip the knife to the other side and repeat. Then turn the roller over to the 3000 grit end and finish.\u003c\/li\u003e\n\u003cli\u003eTest it on a tomato. If it falls through the skin without pressure, you are done.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp dir=\"ltr\"\u003eWHAT IT WILL NOT DO — read this before you buy\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt is built for chef's, santoku, utility and carving knives — blades roughly 1.5 inches deep or more. Short blades sit below the disc and will not sharpen properly. Paring knives, steak knives and pocket knives are not what this tool is for. This is the single most common regret people have with rolling sharpeners of every brand, and we would rather you know now than find out after it arrives.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt will not sharpen a serrated edge, and it needs a magnetic blade. Most kitchen knives are steel and work fine. Ceramic knives and a few high-end stainless ones are not magnetic, and the block will not hold them.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe first sharpen is the slow one. Resetting a badly neglected edge, or a hard Japanese steel, can take real time and effort. After that, touch-ups take a couple of minutes. Anyone promising you a restored edge in sixty seconds is selling you the demo, not the tool.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt makes fine metal dust. That dust is the old edge coming off. Wipe the block down when you finish.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWHAT'S IN THE BOX\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eRolling sharpener, 5.5 × 8.4 cm — wooden body, steel rings, 400 grit on one end and 3000 grit on the other\u003cbr\u003eMagnetic angle block, 10.4 × 5.7 × 2.4 cm — 15° and 20° rubber faces\u003cbr\u003eN52 neodymium magnets\u003cbr\u003eRigid gift box\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSHIPPING\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eShips free from our US warehouse. 1–3 business days to pack, 3–7 days in transit with UPS.
