## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Effective and easy to use
*by J***H on October 24, 2022*

I've purchased 3 knife sharpeners (different brands and types), and this is the first one that has 1. Worked flawlessly, and 2. Allowed me to sharpen some of my "exotically" shaped work and utility knives! The previous sharpeners were inappropriately designed, and did not allow the blades of the specialty knives to pass through the grinder without being obstructed by either the knife's handle or the sharpener's bulky frame. The Mueller sharpener presented absolutely no issues here - it's worth noting that the design is exceptionally ergonomic, and the positioning of its handle provides excellent stability when in use, and offers ample relief from the workspace to keep your hands and fingers safe.Passing the blades through coarse and fine grinders as instructed yielded perfect results, and the sharpened utility blades were able to neatly slice through a single sheet of tautly-held copy paper using a gentle touch (very minimal pressure applied to achieve the cut). My kitchen knives had equally positive results when applied to onions and tomatoes. Interestingly enough, my chef's knife was relatively new, and expected to be mostly undulled, but their performance was undeniably smoother and allowed for effortless, paper thin slicing after a low-rep pass through the Mueller.10/10 - a simple tool that functions exactly as described at an excellent value.

### ⭐⭐⭐⭐⭐ Easier than a whetstone
*by P***L on September 23, 2022*

If you're a connoisseur, then this is not the product for you.If you just need to keep your knives sharp in the kitchen for daily use, then this is a great product.* Very little effort needed to make this work - just run your knife through the appropriate slot about 10-20 times. Start with slot 2 if your knife is really dull, then move on to slot 3 and then finish with slot 4. For typical maintenance, you'll be using slots 3 and 4 only.* Fast use. This only requires 10-20 draws through the appropriate slots to sharpen your knife.* Fast clean-up. This doesn't require oil or water to use, so it comes out, it gets used, and it goes back - all within a minute or two.* Easy to use. I tried to train my wife to use the whet stone, but she was intimidated and hated the setup and cleanup, so she didn't use the whet stone and the knives went dull unless I sharpened them. This product she will use at the drop of a hat - zero intimidation factor.Need to keep your knives sharp for daily use? This works.Need to impress your knife connoisseur friends and keep a ridiculously sharp edge that needs constant upkeep? Then keep to your whet stone.

### ⭐⭐⭐⭐ Decent purchase
*by C***E on September 26, 2025*
