Lou Gean - Grand Master Sharpener


Lou's career had a very innocent beginning as his wife, a full time cosmetologist, was not satisfied with the performance of her beauty shears after a sharpening service from a professional company. As an experienced hairstylist for 30 years, she knew how important it was to have her tools well maintained so she suggested a challenge to Lou which created a new found passion for him in sharpening and servicing beauty shears.

Since then Lou started his career by seeking the best training possible, with Larry & Dennis Brooks at Hamaguri USA in 2008. Shortly after, he sought additional training and has attended the NBTSG Annual Conventions since 2010. During this time and taking several classes, he learned techniques from various well known Master Sharpeners and earned certificates. In May 2013, Lou was invited to a 40 hour intense sharpening training session at Leader Cam in Italy, where he received his 40 hour certificate. Lou has since been sharpening for many professionals including the famous Sam Brocato, in Manhattan, NY and Franco Della Grazia in NJ. In 2012 he earned his first Master certification for Shears, and in 2013 became a Grand Master Sharpener, a Master in both Shears and Clipper Blades. He has achieved Master in Shears every year since 2012! And has served as Shear Certification Judge since 2014. Lou says he has undoubtedly continued to learn something new every year at the conventions and judging shears for Certification.

Now serving on the Board of Directors with the NBTSG, he is a firm believer in the importance of the organization and its purpose! Lou owes his valued knowledge of the industry to the NBTSG, its education and its members. Also he believes in upgrading one's education in this industry as one should never stop learning, and growing. It is essential in making the most of what you can achieve and help to grow one's business and strive to be the best you can be without fear or lack of confidence. As we enter another year at the NBTSG, Lou is looking forward to meeting new faces as well as seeing the old ones too!

Jason Sturm - Master Sharpener


Jason and his family own and operate The Edge Pro in Ankeny, IA.  

Gordon Sturm and his wife Carren founded The Edge Pro in 1990.  For the next 13 years the business grew in their home in Ankeny Iowa, where they focused on sales and sharpening services to the barber, beauty, animal grooming and veterinarian industries.  In 1999 Gordon's son Jason joined the company and by 2003 the business had outgrown its "home" and a storefront location was opened at its current location.  With a storefront open to the public the business has expanded its sharpening services from beauty and grooming scissors and clipper blades to include sewing shears, knives, chainsaw chains, hand tools, paper cutting blades and other misc. items.  We even sharpen the occasional sword.  Since the launch of our retail and wholesale parts store in 2005, we have grown to be one of the largest clipper/dryer parts suppliers in the country! This expanded even more in April 2014 when we purchased the distributor division of Huff’s Wholesale from Bob Huffman of Missouri.  In the past 10 years, Jason has also came to be a recognized authority on clipper blade sharpening and repair and has served on several boards and sharpening guilds.  Our staff has trained hundreds of sharpeners, repairman and women either through our in shop training or in sharpening shows.  As of 2015, we began co-hosting our own sharpening shows with Wolff Industries as well as speaking and vending at different shows across the country.
