The Sharp Fast System was designed to provide ease of use, repeatability, and safety in grinding never before achieved.
Now sharpening a gouge with precision is no longer for the Pros. The S900 gives even beginner Wood Turners the ability to grind difficult gouge shapes over and over with repeatable angles.
The S910 Platform incorporates the same jig concept in a grinding platform providing repeatable angles.
The S920 similar to S910: Heavier duty and but no vertical adjustment.
