It is recommended to not move side-to-side with the tool's edge engaged with the grinding surface, especially when using the SVS-50. Instead, move to a position, ensure the SVS-50 is engaged fully with the USB, and then raise the handle to engage the tool with the grinding surface.

If you want to move use a different part of the grinding surface, lower the handle first, and then repeat the above-listed instructions.

Edge Profile Comments
This is the shape for the tool when shipped by most manufacturers. The edges may be flat instead of slightly concaved (shown exaggerated here).
This shape has a convex edge on the bottom edge.

Advantage Disadvantage
  • The added metal below the center line provides better support for the cutting edge, reducing vibration at the tip.
  • This shape does not burnish the wood as quickly as the traditional shape.
  • The tool is kept sharp longer.
  • This shape will not be as sharp (as the β will be larger).
  • This tool shape cannot be flipped to allow the turner to use the the other side. This is useful when wood builds up on the edge's surface (as it does with oily woods like padauk).
  • It also does not allow for usage in as close a quarter (i.e., when using the tool like a bedan to cut at a rotated angle).
