Zebrawood pencil carvers can be used for clay carving, sgraffito, mishima, sculpting, scraping and more. The wide "V" Tip creates clean wide straight or arced lines. Zebratools are constructed of hand-made exotic zebrawood handles and ultra-sharp stainless steel blades. No other tool can match these tools in performance. They leave little or no burs or debris, carver faster and deeper if desired, with much less resistance and therefore with much less hand/wrist/muscle fatigue. They are sharp enough to carve bone dry or leatherhard clay. They are much sharper than ordinary loop tools, have adjustable blade angle, a built-in stylus, and a comfortable foam grip. The blades are self-sharpening (made of .006" sheet stainless steel ), and are designed with a wider opening in the back to prevent clogging, leaving cleaner, crisper lines. Carving is done with the "beak" down and sgraffito is optimum with the "beak" facing up.
