Convex sharpening provides high cutting capabilities to the blade while maintaining high strength of the cutting edge. The convex edge acts as a wedge, moving apart up the material being cut, which reduces friction and material resistance due to the smaller area of the contact spot.
Application of uniform forces when cutting products of considerable thickness, as well as the highest strength when cutting and cutting strokes are the distinctive features of blades with a convex edge. The TSPROF attach for convex sharpening of blades is provided as a removable adapter, which is easily mounted on the abrasive holder. These adapters provide a uniform change of the angles across the entire width of intake, and the result is the convex edge. The convex edge of blades proved itself very well under shock loads, during cutting of reeds, coastal shrubs and grass, large raw bones, keratinized branches, it is significantly more effective for deep cutting compared to blades with V-shaped sharpening, provided that the blade is of a similar thickness. The reason is less 'sticking' to the material. This form is most suitable for military weapons with long blades, large knives, logging axes.
The main parameters that characterize this attachment are an easy installation, simplicity of design, and low cost.
The kit includes an adapter with a range of 7.2 degrees, mounting hardware for installation.
