The Two-Cherries 515-3437 is a 7-piece wood carving set in a beautiful wooden gift box that is an ideal starter set. The set includes the following: 510-0108 straight chisel (8mm cutting edge), 510-0806 medium gouge (6mm cutting edge), 510-3906 straight v-chisel (6mm cutting edge), three chip carving knives (515-3351, 515-3353, and 515-3358) and a sharpening stone. Two Cherries professional-grade chisels and gouges are hand-forged of German high-carbon steel and have a hardness rating of HRC61. The entire usable length of the blades are hardened in a salt bath, and the cutting edges are machine-ground to a standard of approximately 17 degrees. While these blades may take a little longer to sharpen, their material and manufacturing process ensure they will hold their edges significantly longer than nearly any other chisel or gouge on the market. Made in Germany.
