Which Stone Is Right For Me
| SKU | Thickness (A/O) | Grit | Notes | Application |
|---|---|---|---|---|
| Home-400/1000 | 4/11 mm (2/side) | #400/1000 | Double-sided |
Side #400: heavy touch-ups, chip control, fast bevel set on stainless & PM steels. Side #1000: quick daily sharpening; durable toothy work edge for chef/santoku/petty/EDC. |
| Home-2000/4000 | 4/11 mm (2/side) | #2000/4000 | Double-sided |
Side #2000: fine sharpening & clean deburr; lower friction for smooth push-cuts. Side #4000: pre-polish/finish for glide cuts and plating; not for bone work. |
| Home-3000/5000 | 4/11 mm (2/side) | #3000/5000 | Double-sided |
Side #3000: pre-polish with slight bite—great for sujihiki/gyuto when presentation matters. Side #5000: finishing; remove residual burr and enable glide cuts; presentation grade. |
| Pro-200 | 5/20 mm | #200 | Single-sided | Heavy repair: rapid chip removal and bevel reprofile on severely dull edges; resets geometry fast (not a working finish). |
| Pro-400 | 5/20 mm | #400 | Single-sided | Bevel set & fast burr; aggressive stock removal; leaves coarse tooth for boxes/rope/hard skins; ideal pre-step to #600/#1000. |
| Pro-600 | 5/20 mm | #600 | Single-sided | EDC tooth: coarse, durable micro-serration that matches the fiber scale of cardboard/rope/wood; quick tune-ups; bridges to #1000. |
| Pro-800 | 5/20 mm | #800 | Single-sided | Refines coarse scratches while keeping a “meaty” bite; raises keenness without losing purchase—excellent for poultry/meat prep. |
| Pro-1000 | 5/20 mm | #1000 | Single-sided | Fast sharpening for most kitchen knives; long-lasting working edge that balances bite and glide; the go-to daily finish. |
| Pro-2000 | 5/20 mm | #2000 | Single-sided | Fine sharpening & pre-finish; clean deburr and reduced cutting friction—ideal for smooth veg/protein cuts. |
| Pro-3000 | 5/20 mm | #3000 | Single-sided | Pre-polish with slight bite; smooth push-cuts and neat plating; great for sujihiki/gyuto and refined EDC edges. |
| Pro-4000 | 5/20 mm | #4000 | Single-sided | Fine pre-finish/finish; tunes bite while maximizing glide for presentation slicing. Prefer #1–2K if a toothier edge is desired. |
| Pro-5000 | 5/20 mm | #5000 | Single-sided | First finisher: remove residual burr and true the apex; glide-cut oriented for sashimi/slicers; avoid for bone contact. |
| Pro-6000 | 5/20 mm | #6000 | Single-sided | High-polish finishing; refine the apex and lightly strop for razor feel; push-cut/presentation priority, not for rough prep. |

Frequently Asked Questions
Get the answers you need — sharpen your confidence.
Will #400 be too coarse for my kitchen knives?
No—#400 is the right starting grit for dull edges, setting a new bevel,
and fixing small chips. For a finer bite, follow with #1000 and then the
included leather strop.
Do I need to soak it?
Water only; splash-and-go. Brief soak (~1 min) gives you better feel. Do
not use oil.
How do I choose the correct sharpening angle for different knives?
Angle defines edge character — not right or wrong, just trade-offs:
10–12°/side: Japanese gyuto, slicers, razors — ultimate bite, lower durability
15–18°/side: western chef knives, petty — balanced edge
20°+/side: outdoor, cleaver, work knives — max durability
You can use the Angle Reference Wedge included, or a guided sharpener (our Cheefarcuut Guided Knife Sharpener) if you want precision and repeatability.
Pro tip: stick to one consistent angle family across your knives — it simplifies burr management and speeds up the entire progression.
For more specific angle recommendation, check our digital manual.

I sharpened both sides, but the knife is still not sharp. Why?
Make sure you’ve raised a burr after sharpening each side. Use a stone ≥
1000 grit, refine with single-direction strokes, and don’t forget to use
the leather strop to remove all burrs.
Does the vitrified diamond stone need flattening? How often, and how
should I do it?
Yes — though vitrified diamond holds flatness far longer than resin or
water stones, it still benefits from occasional truing.
When you notice uneven wear, pencil-grid the surface and check. If the grid doesn’t erase evenly after a few strokes, flatten it using a Cheefarcuut flattening plate #140 / #400 or SiC powder (80–220 grit) on glass/granite. Rotate the stone regularly during use to even wear.
Suggested frequency:
Home users: check every 1–2 months
Heavy users/pro sharpeners: every 1–2 weeks
For more info, check our digital manual.

How to use the leather strop without scratching?
Keep the stone angle (optionally +1–2° micro-bevel). Use light, even
pressure ≈ 250 g / 0.55 lb.
Orientation & force: tip backward, spine forward, and pull with the spine leading so the edge trails. No back-and-forth. Do 5–10 light pulls per side.
Feel cue: glide as if skimming off a thin layer of sand from the strop.
