Diamond File, Flexible - Yellow
Code: 056352Product detailed description
SUNCRAFT Shinari – flexible #325 diamond file
The Japanese SUNCRAFT Shinari flexible diamond file is a compact handheld sharpener for quick maintenance of kitchen knives, scissors, slicers and selected garden tools.
The flexible sharpening section adapts to the edge when applied lightly and makes it easier to maintain the working angle. The #325 diamond surface has a pronounced abrasive effect, so only light pressure and a few controlled strokes are required.

Main advantages of the diamond file
Flexible sharpening section
The file flexibly adapts to the edge under light pressure. This makes it easier to guide the tool at a stable angle and reach less accessible areas.
#325 diamond surface
The diamond particles are electroplated onto stainless cutlery steel. The #325 grit quickly restores working sharpness without requiring heavy pressure.
For knives, scissors and other tools
The narrow, flexible profile can be used to maintain kitchen knives, scissors, slicers, sickles, scythes and other tools with an accessible smooth edge.
Lightweight and easy to store
With a length of approximately 213 mm and a weight of only around 27 g, it takes up very little space in a kitchen drawer, tool bag or workshop.
Which tools can the file be used on?
| Tool | Recommended use |
|---|---|
| Kitchen knives | Quick restoration of working sharpness on standard smooth blades. |
| Scissors | Maintenance of the outer bevelled side of each blade after safely opening or disassembling the scissors. |
| Slicers and mandolines | Maintenance of accessible smooth blades that are difficult to reach with an ordinary sharpening stone. |
| Garden tools | Regular sharpening of sickles, scythes and other tools with a suitable smooth edge. |
| Ceramic knives | Only for very careful maintenance of an undamaged edge without chips and using minimal pressure. |
Quick maintenance without preparing a sharpening stone
The file is suitable when the knife still cuts but the edge has lost its original performance. There is no need to soak a stone or prepare a sharpening station – a few light, controlled strokes are enough.
How does the flexible file work?
The sharpening section bends slightly when it comes into contact with the edge. This helps compensate for small deviations in hand guidance and makes it easier to maintain working contact between the diamond surface and the edge bevel.
The surface consists of #325 diamond abrasive. This is a relatively coarse sharpening surface with fast material removal. It is therefore unnecessary to press hard on the file or perform a large number of strokes.
Flexible does not mean the file should be bent by force
The file is designed to flex slightly during sharpening. Do not use it as a pry bar, bend it over a sharp edge or attempt to permanently reshape the sharpening section.
How to sharpen a kitchen knife correctly
- Place the knife on a stable work surface with the edge facing away from your body.
- Place the diamond section against the edge bevel at the knife’s existing angle.
- Using a light movement, guide the file from the heel of the blade towards the tip.
- Treat the other side of a double-bevel knife in the same way.
- Begin with a few strokes and check the result continuously.
- After finishing, wash and dry the knife so that no metal particles remain on the blade.
Use light pressure only
The #325 diamond abrasive removes material quickly. Excessive pressure may unnecessarily increase steel removal, create an uneven bevel or damage a fine edge.
Scissor maintenance
With scissors, primarily sharpen the outer bevelled side of the blade. Do not modify the inner contact surface without the necessary experience, as changing its geometry may prevent the blades from meeting correctly.
If the scissors can be taken apart, work with each part separately. Open non-detachable scissors as far as possible and guide the file carefully away from your hand. Maintain the original bevel angle and use light pressure only.
When should you choose the file and when a sharpening stone?
| Condition of the edge | Suitable procedure |
|---|---|
| The knife cuts less effectively, but the edge is not damaged | The flexible diamond file can quickly restore working sharpness. |
| The edge is very dull | Controlled sharpening on sharpening stones is more suitable. |
| The blade is chipped or deformed | We recommend professional sharpening or edge repair. |
| You require a finely finished edge | After the coarse stage, use a finer sharpening stone or a suitable finishing tool. |

Can kitchen scissors be sharpened with the file?
Yes. Primarily sharpen the outer bevelled side of the blade while maintaining its original angle.
Is it suitable for ceramic knives?
It can be used very carefully on an undamaged ceramic edge. However, it is not intended for repairing cracks or chipped areas.
Does the diamond file replace a sharpening stone?
Not completely. The file is suitable for quickly restoring working sharpness, while a sharpening stone allows more precise edge creation and fine finishing.
Does the file need to be soaked before use?
No. It is ready for immediate use and does not require prolonged soaking like some sharpening stones.
How should the file be cleaned after use?
