## Description

SHARPAL 121N Dual-Grit Diamond Sharpening Stone, Tool Sharpener for Sharpening Knife, Garden Shears, Axe and All Blade Edge : desertcart.co.uk: DIY & Tools

Review: Works Very Well Indeed - Great Product. - I am always sharpening knives both for culinary work and my hobby of making things from leather. As most of us already know a really sharp knife is safer than a dull one, as much less pressure is required to make a cut. I already own a really effective knife sharpening system, but it requires a few minutes to set it all up so it only gets used when I have a few dulled tools. I bought this as something to quickly restore a tool's edge between bouts of major resharpening. I have just tested it on a kitchen knife that was last sharpened about 3 weeks ago. It was pretty dull as others in my household do horrid things to sharp knives, such a putting them in a pile of cutlery on the draining board. With just a few strokes of the coarse side, a hone on the other, and a swift strop with the leather sheath, this put a superb edge on the knife. The tool proved very easy to use and it feels nicely balanced in the hand. The paracord binding on the handle allows a very secure grip and the leather sheath is a clever touch with its ability to be used as a strop. I like it very much and it will be a go-to tool for regular use. It would be especially useful to take on lengthy trips in the outdoors as it isn't either heavy, or bulky, and will always ensure a decent edge on knives used in the field. Highly recommended...
Review: Handy little sharpener! - Bought this to sharpen up my 10 inch shears as I was using a file previously to restore the edge, the difference is night and day!! Very effective at sharpening and incredible value and quality. I was familiar with sharpal stones after buying their diamond plate for my kitchen knives, this is exactly the same but a mini version, easily fitting in a pocket or backpack (or toolbox in my case) Very good little item and well worth the asking price!

## Questions & Answers

**Q: Is water or oil required during the sharpening process?**
A: Avoid using water during sharpening, as it may cause the iron filings on the stone's surface to rust. Testing shows minimal difference in sharpening performance between using oil and dry sharpening, so oil is not necessary.

**Q: After using the stone, dark areas appear on its surface. Does this mean the diamonds have worn off?**
A: No, the dark areas are dried dirt from sharpening, not a sign of the diamonds wearing off. These marks don’t affect performance and can be left as is. For minor marks, use an eraser. For tough stains, clean with Bar Keepers Friend and air dry fully.

**Q: Should I use high pressure when sharpening with this diamond stone?**
A: Avoid applying excessive pressure when sharpening, as it can accelerate wear on the diamond and shorten its lifespan. Instead, use light pressure to maximize the sharpening performance of the diamond particles.

**Q: How long does it last?**
A: The lifespan depends on usage, the hardness of the materials being sharpened, and maintenance. With proper care, it can last many years, even for those sharpening 3 to 4 times a week. Regular cleaning and light pressure extend its durability.

**Q: What is the cause of the rust and how can I deal with it?**
A: The base of this product is stainless steel and will not rust. Any rust is caused by iron filings left on the stone's surface that oxidize if not cleaned. Use Bar Keepers Friend powder to clean it and ensure the stone is fully air-dried.
