Which Stone Is Right For Me
The following grit chart is what Cheefarcut has in current development. The following grits are available for current and immediate purchase and order fulfillment (200/400/1000 pro & 400/1000 double sided). All other grits are scheduled to be released within 30 days.
| 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. |

In-house development based on field experience
Process optimization over years
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.
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.
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.
