## Features

- KAI knife sharpener AP-0308 used both diamond and ceramics as abrasive.This makes it perfect when sharpening hard types of steel.
- With this KAI sharpener you can sharpen knives with a two-sided grind in three phases. From blunt to razor-sharp in no-time!
- Each of the three sharpening slots uses a different sharpening method. The first slot contains two small diamond sharpening stones with grain size 270. Relatively coarse and therefore perfect for the first sharpening phase to restore a blunt edge.
- Step two is the ceramic sharpening wheel with grain 150. A coarser grain than the diamond stones, but with a less aggressive function. Finally you use two ceramic sharpening steels for step three. These have a grain size of 1000 and are, as a result, perfect when polishing the edge
- The KAI knife sharpener has a stylish and solid design and is easy to take with you. If you don't use it you can easily store the sharpener in a transparent plastic cover to make sure no dust or dirt can get caught in between the slots. If you use it you take out the sharpener and use the 'casing' as handle, for optimal stability while sharpening.

### ⭐⭐⭐⭐⭐ perfect sharpner

very good quality and really works

### ⭐⭐⭐⭐ Value for money

Excellent product. Does what it promises. Value for money. Though it doesn’t work on serrated knives.

### ⭐⭐⭐⭐⭐ Sharpens knives well, very easy to use, not expensive
*by S***K on 29 October 2022*

I was a bit skeptical initially on how well this gadget can sharpen knives, having used a few cheap ones in the past. However, the seller has a option to return and Kai seems to be a reputed brand for cutting instruments from Japan (www.kai-group.com). They also have a branch in India (www.kaiindia.in). Usually my knives are sharpened on an inexpensive whetstone, with the correct technique it gets sharp but as a novice, I've never gotten a razor sharp edge. Today when I tested this product (AP-0308), it sharpened the edge much better that what I normally get and it's as sharp as a fresh boxcutter blade. It was tested against cardboard and paper. It was also very quick, took about 5 minutes (2 pulls on the diamond #1, 5 pulls on the ceramics #2, #3) compared to the whetstone that usually takes me about 15 - 20 minutes. Looking at the label, the overall quality of the packaging and product and also the price of the original listed at the Japanese website (appx INR 1350), I think this is a Genuine Kai sharpener. The price is reasonable IMO especially when you look at how much the good quality sharpening stones sell for. The really cheap stones do work but they're like half the price of this while being relatively harder to use.
