First time getting kitchen knives sharpened so I looked around for vendors. Compared to others, Jack Knife was quick and priced right. Sharpens knives while you wait for immediate turnaround. And Jack is super friendly so doing business with him is a pleasure.

Jack Knife is wonderful. Highly recommend for your knife sharpening needs. Did an excellent job on all my knives and even brought back to life my antique butcher knife. Can not say enough good things about this company.

I just met with Jack and he sharpened 17 of my knives in 30 minutes. He and his assistant Matt were courteous and gracious. I chose Jack because he is a Veteran and I believe in supporting those who serve our country. I found his skills to be exceptional as well as his personality. I'd recommend him to anyone!

If you’re a working Chef, or a Culinary Student like I am you need consistently sharp knives. After visiting Jack’s my knives have never been sharper! Jack may want to change his slogan to “Sharper than New” he’s also really fast, and affordable. Thank You Jack, for your great service.

Jack did a great job sharpening my gardening tools at the Old Greenwich Farmers Market. I had bent a tip of my favorite pruners and he was able to salvage them.

Got knives sharpened last week. Great Job and price was quite reasonable. However I am also giving 5 stars also because the service and attitude were great. Jack gave me several tips on which knives to buy; which knives are keepers versus throwers (throw away after they dull). Suggestions on how to store and wash knives.

Service was great, easy, and nicely priced. I dropped off my knives and pretty much as soon as i got home they were ready. The knives were sharpened very well. Slicing and cutting is noticeably easier compared to when I just used to sharpen them just using a steel.

Brandon King2 reviews

Jack is the best in the business.. there is nobody on his level when it comes to pricing and quality of service. Questions? He answers them. Think there is a knife he can’t sharpen? Highly unlikely. He can sharpen it all! Great all around service. Highly reccommend.
