Customer Reviews

"highly recommend the quality of the workmanship"

We have had our knives sharpened several times by RazorSharp Knives including a genuine Japanese Gyuto knife and can highly recommend the quality of the workmanship, and the service is absolutely marvellous which also includes cardboard sheathes to remind us the knives have  just been sharpened so be careful!
