Since 2004, the Tharwa Valley Forge has been using Radiusmaster grinders for our Knifemaking Classes. Hundreds of students have ground their first knife blades using a Radiusmaster after a short safety briefing and grinding demonstration.
We have used the original Radiusmaster, the Select-a-rad and the new Radiusmaster II, in both the variable speed and fixed speed configurations.
The variable speed motor allows those with less experience in using machines to start slowly and build confidence as they increase the speed. The variable speed motors also allows delicate grinding and sharpening without overheating or burning of the steel, and the grinding of softer material like wood, bone and horn. The different radius’ available allow efficient shaping of handles.
The Radiusmaster solid construction and design require allow long periods of service, without the need for maintenance. The accessories are well made, and adjustable. Cleaning is easy, and belt changes are quick. Belt life is vastly improved over other grinders I have used, saving money and time. Their compact size take up less room in the workshop.
Using the Radiusmasters has cut the grinding time in half in the classes, allowing more time for other processes. Beginning students are producing superior results on their blade grinds. Experienced users are producing blade efficiently with a high standard of finish.
I have made my investment back many times with the Radiusmaster through longer belt life and improved productivity. Don’t waste valuable time with inferior options.
