#現貨供應｜新国作 XinGuo 鑽石砥石

高含量鑽石磨粒 × 高自銳性 × 快速下鐵

#400／#1200／#4000／#8000

這次到貨的新国作鑽石砥石，實際試磨後最大的感受很直接：

下鐵速度真的快，而且砥石表面的自潔能力非常好。

但它又不是一般燒結式或電鍍式鑽石板那種偏硬、直接刮削的研磨手感。

採用水泥系基材澆築，並搭配樹脂及其他結合劑，在保留鑽石磨粒強勁切削能力的同時，研磨接觸感依然順暢、容易掌握。

主要針對高硬度、高耐磨的現代鋼材，尤其在高鎢合金等難研磨鋼材上，更能展現鑽石磨料的優勢；一般傳統碳鋼與不鏽鋼，自然也能輕鬆應付。

━━━━━━━━━━━━━━━━━━━

為什麼鑽石砥石可以磨得這麼快？

新国鑽石砥石採用約 38% 高含量鑽石磨粒，搭配特殊結合系統製成。

鑽石本身具有極高硬度，因此面對高硬度、高耐磨鋼材時，依然能提供相當積極的切削能力。

但真正影響一顆砥石好不好用的，不只是「磨料夠不夠硬」。

自銳性、自潔性與可修正性，同樣非常重要。

相較於較為剛硬的燒結式或金屬結合類鑽石產品，這類結合方式能帶來較柔和、順暢的研磨接觸感。

所以實際磨刀時，可以同時得到：

「鑽石磨粒的高切削效率 × 接近天然砥石般的研磨回饋」

不是只有快而已，研磨過程中的手感與控制性也是這系列相當有意思的地方。

━━━━━━━━━━━━━━━━━━━

自銳性｜讓新的鑽石磨粒持續工作

研磨一段時間之後，任何磨粒都會逐漸產生磨耗。

新国鑽石砥石在使用過程中，結合劑會隨著研磨適度磨耗，使逐漸鈍化的磨粒脫落，同時讓內部新的鋒利鑽石磨粒持續露出。

這就是所謂的：

Self-Sharpening｜自銳作用

因此砥石工作面能隨著使用持續更新，降低因磨粒鈍化、磨屑堆積而造成切削效率快速下降的情況。

這也是我們自己實際試磨後非常有感的一點：

磨面自潔速度真的很快，不容易磨沒多久就變得又黑又滑。

對需要長時間連續磨刀的人來說，這點真的很舒服。

━━━━━━━━━━━━━━━━━━━

不只傳統鋼材｜越難磨的鋼材，越能感受到差異

一般碳鋼、不鏽鋼當然可以輕鬆應付。

但如果平常經常接觸：

・高硬度不鏽鋼

・高耐磨工具鋼

・現代粉末鋼

・高鎢合金鋼

・其他難研磨鋼材

鑽石磨料的優勢會更加明顯。

尤其部分含有鎢（W）、釩（V）、鈷（Co）等合金元素，並具有高度耐磨性的鋼材，使用一般傳統砥石研磨時，往往需要花費更多時間。

甚至部分極高耐磨的模具鋼，在某些傳統砥石上會出現下鐵效率非常低、刃口難以快速建立的情況。

這時新国鑽石砥石的高切削能力就會更加明顯。

對需要大量磨刀的職人，或手上高硬度、高耐磨刀具比較多的玩家來說，可以省下不少研磨時間。

━━━━━━━━━━━━━━━━━━━

🔥 Now In Stock | XinGuo Diamond Sharpening Stones

High Diamond Content × Strong Self-Sharpening Action × Fast Metal Removal

#400 / #1200 / #4000 / #8000

After testing these newly arrived XinGuo diamond stones ourselves, the first impression was very straightforward:

They cut extremely fast, and the stone surface has excellent self-cleaning ability.

At the same time, they do not feel like the hard, aggressive scraping sensation typically associated with sintered or electroplated diamond plates.

XinGuo uses a cement-based cast matrix combined with resin and other bonding agents, allowing the stone to retain the aggressive cutting power of diamond abrasives while still providing a smooth and controllable sharpening feel.

They are designed especially for modern steels with high hardness and high wear resistance.

The difference becomes particularly noticeable on difficult-to-sharpen steels such as high-tungsten alloys, while conventional carbon steels and stainless steels are naturally no problem at all.

━━━━━━━━━━━━━━━━━━━

✨ What Makes XinGuo Diamond Stones Different?

✔ High Diamond Content｜Diamond abrasive content of approximately 38% for fast and consistent metal removal

✔ Excellent Self-Sharpening Action｜Fresh sharp abrasive particles are continuously exposed during use

✔ Strong Self-Cleaning Ability｜The surface is less prone to loading, glazing, and slipping from accumulated swarf

✔ Special Cast Construction｜Cement-based matrix combined with resin and other binders for a balance of cutting speed and sharpening feedback

✔ Suitable for High-Hardness Steels｜Effective even on highly wear-resistant tool steels and powder metallurgy steels

✔ #400 to #8000 Range｜Covers repair, edge setting, refinement, and final finishing

━━━━━━━━━━━━━━━━━━━

💎 Why Can a Diamond Stone Cut So Fast?

XinGuo diamond stones use approximately 38% high-content diamond abrasive together with a specialized bonding system.

Diamond itself has extremely high hardness, allowing it to maintain aggressive cutting performance even when sharpening very hard and wear-resistant steels.

But the performance of a sharpening stone depends on more than simply how hard its abrasive is.

Self-sharpening ability, self-cleaning performance, and surface renewability are equally important.

Compared with more rigid sintered or metal-bonded diamond products, this type of bonding system produces a softer and smoother contact feel during sharpening.

In practical use, the result is a combination of:

“The cutting efficiency of diamond abrasives × A sharpening feedback closer to that of a natural stone.”

It is not simply about speed.

The feel, feedback, and controllability during sharpening are also some of the most interesting characteristics of this series.

━━━━━━━━━━━━━━━━━━━

⚡ Self-Sharpening | Keeping Fresh Diamond Abrasives at Work

All abrasive particles gradually become worn with continued use.

With XinGuo diamond stones, the bonding material wears at a controlled rate during sharpening.

As older abrasive particles become dull, they are gradually released, allowing fresh and sharp diamond particles inside the stone to become exposed.

This is known as:

Self-Sharpening Action

Because the working surface continuously renews itself during use, the stone is less likely to suffer a rapid drop in cutting performance caused by dull abrasives or accumulated swarf.

This was also one of the most noticeable points during our own testing:

The surface cleans itself very quickly and does not become dark, glazed, and slippery after only a short period of sharpening.

For anyone who sharpens continuously for long periods, this makes the process significantly more comfortable.

━━━━━━━━━━━━━━━━━━━

🔪 Not Just for Traditional Steels | The Harder the Steel, the More Noticeable the Difference

Standard carbon steels and stainless steels are naturally easy for these stones to handle.

But the advantages of diamond abrasives become much more noticeable if you frequently work with:

・High-hardness stainless steels

・Highly wear-resistant tool steels

・Modern powder metallurgy steels

・High-tungsten alloy steels

・Other difficult-to-sharpen steels

Certain steels containing alloying elements such as tungsten (W), vanadium (V), and cobalt (Co) can exhibit very high wear resistance.

When sharpened on conventional stones, they can require considerably more time.

Some extremely wear-resistant die and tool steels can even show very low metal-removal rates on certain traditional whetstones, making it difficult to establish an edge efficiently.

This is where the aggressive cutting ability of XinGuo diamond stones becomes particularly noticeable.

For professional sharpeners or enthusiasts who own many high-hardness, wear-resistant knives, they can save a considerable amount of sharpening time.

━━━━━━━━━━━━━━━━━━━

📊 Which Grit Should You Choose?

🔸 #400 | Coarse Grinding / Repair

The main choice when fast metal removal is required.

Suitable for:

・Edge repair

・Re-establishing bevel geometry

・Sharpening jobs requiring heavier steel removal

━━━━━━━━━━━━━━━━━━━

🔸 #1200 | Everyday Main Stone

If you only plan to start with one stone, #1200 would be our first recommendation.

It offers plenty of cutting speed while still leaving a highly practical kitchen-knife edge.

It works very well for both establishing an edge and routine sharpening.

🔥 #1200 is currently sold out due to strong demand.

Additional stock has already been urgently ordered, and customers may register for restock notification in advance.

━━━━━━━━━━━━━━━━━━━

🔸 #4000 | Medium-Fine Refinement

Designed for further refining the edge and removing the previous sharpening scratches after the basic bevel has already been established.

A good choice for users who want a balance between practical cutting bite and a more refined edge.

━━━━━━━━━━━━━━━━━━━

🔸 #8000 | Fine Finishing

The highest finishing grit in the series.

Suitable for further refining the final edge or completing a full sharpening progression together with the lower grits.

#400 → #1200 → #4000 → #8000

From coarse repair and edge establishment to refinement and final finishing, the full four-stone set provides a complete sharpening system.
