Wonderful job! Easy to pick up.My Japanese knife got her life back!!Thank you so much. Highly recommended.

John is great to work with! He did an excellent job sharpening out kitchen knife set. Beautiful. Very reasonably priced. We will be back for sure. Nothing like breaking down a chicken with a sharp knife :)

John Kuipers is by far the most thorough educator and a master in the world of sharpening. He offers private training to those seeking a career in sharpening. He is structured and clear about his focus on you. We are forever grateful him and to our investment in learning a new trade. We highly recommend John Kuipers for his continued support and service at Wicked Sharp, LLC!

He’s BEEN THE GUY for many years. Every time he fixes the problem with my sheers which we all know could be high end SHEERS which cost thousands, It’s an honor to have this man sharpen them for me. Trust 100%

He did an awesome job on my knife and multitool. Highly recommended.

John is amazing the only guy who touches my shears.

Mans a saint! Not only did he give me the knowledge to be successful, he’s always been there after training if I had to call and ask a question.
