Over our history, we’ve also provided both OEMs and end users with financial savings. When it comes to the purchase price of our standard and custom form fill and seal blades, our quotes have beaten the rates given by overseas suppliers.

What Our Customers Are Saying

I just wanted to pass along some good news to you and a big “thank you”. We were recently able to test the knife that you supplied us for our “hard-to-cut” material. The “puncture and tear” method that works with other materials would not work with this material.  We had to have a complete cut and this knife provided exactly what we needed without making any machine modifications.  Thank you for all of your time and assistance with this project.

What Our Customers Are Saying

I have been buying custom manufactured saws and knives from York Saw and Knife for over 35 years and have always found their quality and customer service to be exceptional.
