Our Philosophy
Quality, Service, and Value
Cost-Effective Solutions Sharpening your existing tools and blades is significantly more cost-effective than constantly purchasing new ones. We help you maximize your investment while maintaining peak performance.
No Job Too Big or Small We proudly serve everyone – from community members walking in with kitchen knives and lawn mower blades to major corporations requiring industrial-scale precision sharpening. Our small-town values mean every customer receives personal attention.
Cutting-Edge Technology Our investment in modern equipment like the Evolution K850-M cold saw grinder ensures we can handle the most demanding industrial applications while maintaining the precision craftsmanship our customers expect.
Three Decades of Sharpening Excellence
Dave Magadanz founded Riverside Tool and Carbide in 1989, starting as a small sharpening business operating from his garage. As word spread about the quality of our work, business grew rapidly, leading to the construction of our current facility at 1907 Mill Street in New London, Wisconsin in 1991.
On June 28th, 2024, Dave retired and proudly passed the business to Jason Flease, one of his longest and most dedicated employees. Jason joined the team straight out of high school in 2008 and has worked alongside Dave for over 16 years, learning every aspect of the craft, while also being a local firefighter for 10 years. It was always Dave and Jason’s shared dream for Jason to one day take over the business, ensuring our tradition of excellence continues.
Why Experience Matters

With over three decades in the business and Jason’s 16+ years of hands-on experience, we understand that every blade and every customer has unique needs. Our deep knowledge of metallurgy, cutting angles, and industrial applications ensures optimal results every time.
