Suction Knife Sharpener Reviews

Sharpening Knife with Suction Knife Sharpener

“I decided to dive in and try this one without many expectations, and boy was I wrong! 1 or 2 uses on a knife, and it’s really sharp, 3-5 on a knife without a real edge, and it actually puts an edge on it that would cut a tomato with ease. Highly recommend this sharpener.” – Osborne H.

“I’ve used a butcher’s steel for years but lacked the skill to get a really good edge, plus I’ve had too many accidents with it. So, I tried this suction knife sharpener, and it put a wonderful edge on my gran’s ninety-year-old carving knives, which needed regrinding. And even I can’t manage to injure myself with it. The best thing to do is keep going through the process until the blade feels right.” – Jason M.

“This will put a very good sharpening to any knife. I tried it on the bluntest knife I could find (one that wouldn’t cut a banana) and brought it very much back to life and would slice any soft tomatoes. I have ordered two more for my colleagues.” – Natalie C.
