RSM 4 automatic

4th generation of an automatic radius sharpening machine.
Developed together with Zandstra Sport (in the Netherlands).

It is intended for short track skates, long track skates and tour skates.
Has attended the Olympic Games several times.

Five radius templates of your choice are included.

Highest precision

The vertical grinding wheel that moves automatically from left to right will guarantee an exact copy of the contour of the template. By using a fixed holder you get a proper shape in the blade.

Work horse

If you are looking for a way to profile your short track blades, long track blades and tour skates, look no further. This is an automatic sharpening station of the highest quality. It is heavy and very durable, made for working vibration-free all day long.


After the profiling is complete you need to hone your skate using a very fine hand hone/ whetstone mounted in an assembly like the Slijptafel from Zandstra Sport. Because of the accurate sharpening, removal of skate blade material and honing is kept to a minimum.
