Review: I have been doing my own knife sharpening as long as I can remember back to boy scout days. i am now in my 7th decade and have used a lot of hand sharpening tools, Smith, Lansky, chef's choice, worksharp,arkansas stones, diamond stones etc. For just out of the box, something recognizable in a kitchen drawer and used by those who dont sharpen knives as a hobby or profession this one made in Japan does as nice of a job as I have seen with 3 simple steps. For those who found this item bereft of sharpness I think they got a lemon or it was broken in some way. I did my wifes whole drawer of knives over christmas as well as my sis's; dependable, straightforward. The price was worth it when i sat down with my two adult daughters and they got the hang of it easily. So many features of so many sharpeners, this is a nice conglomeration from the grit on the stones, the stability, the angle of the sharpening surfaces. hell even the non slip inserts on the feet that hold it in place on the table top. Well made but light weight and the surfaces are kept shielded from kitchen drawer tool impacts by the sliding sheath. Well Done KAI
Review: So when I first ran my Shun knife through it, I’ll admit I was scared. The first pull when I heard and felt the grinding, I had shed a tear. But with the second and third stages it was a lot smoother. The end result was my blade was as sharp as I first got it. Highly recommend.

## Questions & Answers

**Q: I lost my instructions how to use this sharpener can someone share what their instructions state?**
A: Unfortunately my son opened the box and I too don’t have the instructions. Sorry

**Q: Can this also sharpen scissors?**
A: No. This sharpener is for straight knife blades honed to a particular angle. It's highly unlikely that any scissors would have the same angle. Search instead for scissor sharpener, e.g.

**Q: Is the 16 degree angle suitable for western kitchen knives?**
A: It might be, but I wouldn't use it unless they were already sharpened at that angle.
It does a GREAT job on my Shun knives and makes sharpening very quick with just a few strokes.

**Q: What's the difference between this model ap-0138 and the ap-0308? https://www.amazon.com/dp/b0061wz7a4**
A: Not sure I only bought one, so I'm not a good reference.  Perhaps reading the information provided ,reviews or looking it up on the internet would be a proactive course of action.
