Knife Sharpeners,400/600 Grit Folding Pocket Diamond Whetstone, Handheld Double Sided Sharpening Stone for Outdoor Camping Kitchen Garden

Handy tool for when working in the garden. Can help maintain a nie keen edge on various tools. Nice and compact, and great functionality. Handy little sharpener.

This works fine for now. Perfectly happy with it. Time will tell if it lasts or not.

I had one of these for the past 5 years and it’s now worn out so I bought a new one. It’s great! Very effective and will last for another five years.

Really handy, quick way to get a sharp edge back on a knife. I use this daily to maintain the edges on my kitchen knives. Also very inexpensive, compared with a quality steel. Delivered within 24 hour too.

I bought this specifically to put the edge back on a ceramic knife, which it did no problem. There seems to be quite a lot of difference between the two sides, i.e. the 400 feels very rough (more like 200) whilst the 600 seems very smooth (more like 800), but it does ultimately it does the job. I was worried that, being foldable, it would be a bit wobbly when sharpening, but it's perfectly sturdy.

Very easy to use and store

Like these for honing garden tools and household knives

This is an effective tool for keeping blades sharp, assuming a) good quality steel blade and b) blades do not require major sharpening from a very blunt state.
