Round rasps (also known as rat tail rasps) are gently rolled as they are pushed through the cut to engage as many teeth as possible. At 90 degrees to the workpiece the round rasp produces a U shaped channel, at lower angles they form one end of an ellipse, they are also a very instinctive roughing tool for three dimensional work - cutting evenly in all directions, the round rasp is ideal for finding and establishing intersections between surfaces before removing the bulk of the waste with a hand or halfround rasp.
As fine and precise as a conductor's baton, the 150mm No.14 grain round rasp is a delightful tool for tight curvatures and smaller scale work.
The 200mm No.11 grain round rasp is a 'normal' medium sized rasp for general work.
The hand stitched Liogier 300mm No.9 grain 'Queue de Rat' (rat tail rasp) has an overall length of just over 17 inches with an aggressive yet controllable grain.
The key to a Liogier rasp's performance is in the craftsmanship, meticulously perfecting each stage before moving on to the next. The blanks are beautifully forged, ground and polished before a stitcher even gets near them. The blank is treated with ever increasing reverence as more time is invested in it, and when the lengthy stitching process is complete, it goes on to the transformational stage of heat treatment where the crystalline structure of the steel is carefully reset into a hard, tough, and above all wear resistant material.
Before it can receive it's plump, narrow waisted beechwood handle, proudly marked with the Liogier logo, the newly created tool is gently wafted with compressed air and ground walnut shells to gently clean the steel to a smooth matte surface.
The rasp is now ready to enter service with it's new owner.
It is important to keep your rasps free of wood debris that can attract and hold moisture against the surface. A brass bristled brush is the ideal tool for cleaning the teeth, for greater protection we highly recommend storing in an enclosed space with an open pot of Shield Technology ToolGuard VCI.
