Multiple purpose tool grinding device

A tool sharpening device having a rotary grindstone with a planar end grinding face, a tool support having a support face defining a first support surface for supporting a tool to be sharpened against the end grinding face, and linear guide means along which the tool support is displaceable in use of the device, the linear guide means extending transversely of the axis of rotation of the rotary grindstone, and the location of the linear guide means being such as to guide a tool supported on the tool support face to transit across the end grinding face of the rotary grindstone, wherein:

• the tool support has guide engagement means for enabling its releasable engagement with the linear guide means
• the guide engagement means and the linear guide means are selectively engageable so as to locate the tool support in a selected one of two distinct, predetermined orientations relative to the grindstone in each of which the tool support face is inclined at a respective one of two different inclinations to the plane defined by the end grinding face of the grindstone,
• said tool support face defines said first tool support surface and a second tool support surface at an obtuse angle to each other and intersecting at an adjoining end edge extending transversely of the axis of rotation of the grindstone, and
• said first tool support surface has a lateral edge extending transverse to said adjoining end edge and an upstanding shoulder extending along the lateral edge and terminating at the adjoining end edge in an end face substantially coplanar with said second tool support surface, whereby a tool supported on the first tool support surface in use of the device can be located securely on the tool support against said shoulder whereas a tool supported on the second tool support surface can project therefrom.
