(K1:09), measuring 42.6 cm in length, 11 cm in width, 0.8 cm in thickness, and weighing 454.2 g. Made of altered dolomities limestone, with dark green coloration on both sides and a brownish center. The artifact was broken in the middle and has been reassembled. The artifact is relatively wide, with thin sides and a slightly thicker middle section. The blade is long and triangular, with sharp edges on both sides. The upper section narrows toward the center, with a small notch at the tip. The tang is narrow, with shallow serrations on both the upper and lower edges. Seven evenly spaced parallel lines are carved along both sides of the blade’s main body. The tang is rectangular, thicker in the middle, with dull edges ground on both sides. The lower edge of the tang is elongated and slanted at the end. A circular perforation (1.2 cm in diameter) is drilled at the junction of the tang and blade. A "stepped" mark remains on one side, left from the cutting process.
