About Dorn & Hart Microedge

In 1946, working out of a garage and with the use of a hand grinder, a microscope, and some basic hand tools, Vernon Dorn began his business of knife re-sharpening and machine repair services. Each Monday morning, Mr. Dorn would drive into the city and visit local hospitals to pick up knives and machines needing repair. As he met with his clients each week, his promise was to have the knives and machines he picked up returned and ready for use by the following Friday. In fact, on many occasions Mr. Dorn would work late into the evening to make certain that his promise was kept.

Over the next decade and a half as Mr. Dorn saw his business grow, he found it necessary to take on an apprentice to help him keep up with the increased demand for his rapid turnaround services. It was 1963 when Mr. Dorn then hired Ken Hart, a high school student with very good mechanical skills, to help with the deliveries and eventually to work on the machines. With the two working together, they became very efficient and their reputation quickly spread to hospitals and labs across the country. As business steadily continued to increase, Dorn & Hart moved out of the garage and into a new building where packages from all over the country began to fill the mailbox.

As the techniques used in histology and pathology has evolved over the years, so has Dorn & Hart. In fact, Dorn & Hart was a pioneer in the industry with tungsten-carbide knives and today’s tungsten-carbide blades are all based on the early prototypes Dorn & Hart made in the 1970's. With nearly 40 years of experience in the manufacturing and reconditioning / re-sharpening of tungsten-carbide knives, while always maintaining the high standard of quality and the commitment of fast turnaround services for their customers, no other company or person comes close to measuring up.

Dorn & Hart Microedge operates out of the same shop to this day and service customers from around the globe. In fact, Ken Hart still travels locally around the Chicago area performing service calls at hospitals, labs and universities, while always checking every knife and machine personally before it is sent back to the customer. Additionally, Dorn & Hart Microedge has recently expanded their product line with a goal of becoming a "one stop shop" for resin histology and hard tissue supplies. Dorn & Hart Microedge is also a proud member of the National Society for Histotechnology (NSH) and a sponsor to the Hard Tissue Committee.
