VogueDiamond Knife Sharpening Steel 25.5 cm/10 inch, Black, Material: Diamond Steel, Microcrystalline Surface Produces Precise Sharp Results, Rockwell 99 degree Hardness Rating, CC199

Very nice

I like it. Its good. Does what it does. 10/10

Good value for money won't last forever but at this price you can replace it every 3/4 months

It will put the edge back on your knife, but doesn't seem great quality. We'll see how long the coating lasts.

Was very good value for money and easy to use

Not too sure how my fellow reviewer rated this product so low! I am also a 'pro chef' and have had several of these over the years, so have my colleagues, and we have all agreed on how good they are - especially for the money! The thing is you need to keep the blade at around a 30 degree angle rather than the more usual 45, it will blunt your knife at that angle and end up grinding the blade away to nothing. They also work especially well with the more expensive Japanese folded steel blades as a normal steel simply isn't up to the job.

Not up to professional class.

Not actually Vogue, Cheap knockoff, do not buy. Lost all sharpening ability within 2-3 weeks and nearly ruined my rosewood handled Vic. Don't risk your knives!
