Review: Oblivion Dual Grit Knife Sharpener — Worth Buying in 2026?

Coarse side (grey) for repairing dull edges, fine side (dark) for finishing. No oil needed.
A dull knife is actually more dangerous than a sharp one. It slips off food instead of cutting through it, which is how people cut their fingers. If your Godrej or Prestige knife can barely get through a tomato without squashing it, the Oblivion Silicon Carbide Stone might be exactly what your kitchen needs.
We tested it over several weeks on four different types of knives to see if it actually delivers on the promise.
🏆 Our Verdict: Oblivion Dual Grit Stone
4.6 / 5The Oblivion sharpening stone delivers a noticeably sharper edge than any plastic pull-through sharpener we have tried. It works well on Indian stainless steel knives and the silicon carbide build means it will last for years. The only real barrier is the learning curve — you need 10 minutes of YouTube watching before your first session.
What works
- ✔ Restores a razor edge that pull-through sharpeners cannot match
- ✔ Works on Godrej, Prestige, Pigeon, Crystal and local knives
- ✔ Also sharpens scissors and chisels
- ✔ No oil needed, just water
- ✔ One purchase lasts for years
What does not
- ✖ Real learning curve, not a 10-second fix
- ✖ Will crack if dropped on a hard tile floor
- ✖ Does not work on serrated bread knives

Will It Work on My Knives?
Most Indian kitchens have stainless steel knives from brands like Prestige, Godrej Cartini, Pigeon, Crystal, or unbranded local market picks. We tested the Oblivion stone on all of these and the results were consistent. Every knife came away noticeably sharper after a single session.
Here is what we used it on:
- Godrej Cartini vegetable knife — restored the factory edge completely after 15 minutes
- Prestige chef knife — went from struggling with capsicum to slicing tomatoes paper-thin
- Local sabziwala knife (soft iron steel) — sharpened up fast, softer steel responds well to the coarse side
- Kitchen scissors — the flat stone surface works on scissors too, though it takes some practice with the angle
What it will not work on
Do not use this on serrated bread knives. The flat stone surface will damage the teeth. You need a tapered sharpening rod for those. Ceramic knives can technically be sharpened on silicon carbide but we would not recommend it without knowing what you are doing.
Build and Materials
The stone is made from silicon carbide, also called carborundum. It is the same material used in professional knife sharpening blocks that cost two to three times more. The block is heavy for its size, which actually helps keep it stable during use.
What is Dual Grit?
Think of it as two tools in one. The coarse side grinds down nicks and repairs seriously dull edges. The fine side polishes the edge so it slices cleanly through skin of a tomato without tearing. You always start on the coarse side and finish on the fine side.
The stone comes with a rubber or plastic base that grips the counter well. You will not need to hold it down with your second hand on most surfaces, which makes the actual sharpening motion safer and more consistent.
Whetstone vs. Plastic Pull-Through Sharpeners
Most Indian homes still use those cheap plastic V-shaped sharpeners you can buy at D-Mart for ₹50. They do technically sharpen your knife, but the trade-off is poor.
| Feature | Oblivion Stone | Plastic Pull-Through |
|---|---|---|
| Sharpness achieved | Razor sharp | Moderate at best |
| Effect on blade | Controlled, minimal metal removal | Strips metal fast, shortens blade life |
| What it works on | Knives, scissors, chisels, tools | Knives only |
| Cost over time | One purchase, lasts years | Wears out, needs replacing |
| Skill required | 10 min learning curve | Zero, just pull through |
The plastic sharpener wins on convenience. The stone wins on everything else. If you want your Prestige knife to still be usable five years from now, the whetstone is the smarter investment.
How to Use It (First Time)
The honest version: watch a short YouTube video before your first session. Maintaining a consistent 15 to 20 degree angle is the only skill involved and it takes one session to get the hang of it. Here is the basic process:
- Soak the stone in water for 10 to 15 minutes until air bubbles stop coming out of the surface.
- Place it on a stable surface. Use the rubber base provided. Put a damp cloth underneath if you are on a smooth granite countertop.
- Start on the coarse side. Hold the knife at roughly 15 to 20 degrees to the stone and push the blade forward across the stone as if you are trying to slice a thin layer off the top.
- Do 10 to 15 strokes per side on the coarse grit, then flip to the fine side and repeat with lighter pressure.
- Test on paper. A properly sharpened knife will slice through a sheet of A4 paper cleanly with no tearing.
Frequently Asked Questions
Does this work on Indian stainless steel knives like Prestige and Pigeon?
Yes. We tested it on knives from Prestige, Godrej Cartini, Pigeon, Crystal, and local steel market knives. All of them sharpened up well. Indian stainless steel is generally on the softer side which actually makes it easier to sharpen on silicon carbide.
Do I need to buy oil for this stone?
No. Water is all you need. Soak the stone for 10 to 15 minutes before you start and add a splash of water during the session if the surface looks dry. You do not need honing oil.
Can I sharpen serrated bread knives on this?
No. Flat whetstones are designed for straight-edge blades only. A serrated knife needs a tapered ceramic or diamond sharpening rod to get into the individual teeth. Using a flat stone on a serrated knife will damage it.
Is this fragile? Will it break if I drop it?
Yes, it is brittle like a ceramic plate. If you drop it on a tiled kitchen floor from counter height, there is a real chance it cracks. The silicon carbide material is very hard but not impact-resistant. Keep it stored in the included case when not in use.
Can a complete beginner use this?
Yes, but budget 10 minutes to watch a whetstone tutorial on YouTube first. Maintaining a consistent angle is the only tricky part, and most people get the feel for it within the first session. The results are noticeably better than any pull-through sharpener even for a first-timer.
Final Verdict
If you take cooking seriously, a whetstone is one of the most useful kitchen tools you can own. The Oblivion Dual Grit Stone gives you professional results without a professional price tag. The learning curve is short and the results make every knife in your kitchen feel new again.
