## 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.
