## Questions & Answers

**Q: Will this sharpen steel fabric scissors?**
A: Yes, worked fine on mine. Make sure that you sharpen the correct side of each blade.

**Q: sirve para cuchillos dentados?**
A: Si funciona exactamente

**Q: Why did the seller not put the blade angle in the description?**
A: I just got mine and checked the angles.  It sharpens at 17°.  That's great for a kitchen knife, but too acute and fragile for a hunting knife.

**Q: So many of these esharpeners take off too much material, is this one any different?**
A: My sharpener chipped a ceramic blade so yes it takes off too much material. This sharpener has 3 different grooves for rough to fine sharpening.  With metal blades just pay attention to how much force to apply.
