The Zebrawood "Teardrop Fluting Tool" is designed to create a smooth sided rounded groove. Zebratools are constructed of hand-made exotic zebrawood handles and ultra-sharp stainless steel blades (.004"). No other tool can match these tools in performance. They leave little or no burs or debris, carver faster, with much less resistance and therefore with much less hand/wrist/muscle fatigue. They are much sharper than ordinary loop tools, have a built-in stylus, and a comfortable foam grip. The blades are self-sharpening (made of sheet stainless steel ), and are designed with a wider opening in the back to prevent clogging, leaving cleaner, crisper lines.
Use all appropriate safety precautions. Keep out of the reach of children.
