STAINLESS STEEL!Ronin Gear's new #215 Practice Butterfly knife features polished stainless steel skeletonized handles and a 1.25" wide, rounded; perforated dull blade (blade cannot be sharpened!) that is ideal for safe training! Built to the same high standards as found on real Balisong selling for hundreds of dollars! Top quality; all metal construction with optimal weight and balance. 5" closed; 4" blade. Legal under most state & local laws as it is a 'training replica' and cannot be made into functional knife
