The mark consists of a literal portion "Mjölnir" written in stylized black letters. The literal portion "Mjölnir" is centered in the mark above a perspective view of a stylized weapon, comprising a handle with a pointed pommel with a knurled upper portion, a laterally-elongated pentagonal head, and a tapered handle joining the two. The narrow end of the handle has a beveled ring at the base, next to the knurling of the pointed pommel. The end of the handle closest to the head of the weapon is wider than the head and shows stylized wood grain where it meets the head. A two-pointed Celtic knot is positioned along the length of the handle. The head of the weapon is pierced by the handle and has a covering comprising a top and front facing joined by simulated black stitching. The stitching outlines each visible face, as well as the upper and lower striking faces of the weapon, which are not pictured. The front face is covered by a Celtic knot on a black face, outlined in white trim. A single row of stylized white beads surrounded in black outline the white trim. The front face of the head is decorated with a five-pointed Celtic knot symbol. The top of the weapon comprises two identical design portions, each having two three-pointed Celtic knot symbols aligned base to base and extending diagonally from the back face of the head of the weapon to the front across a black field, outlined in white and again in black. The center of the top comprises a stylized circular handle end with a single cross-hatch in the center. The handle end is enclosed in a black ring which is further enclosed in a white ring. A literal portion "Breakfast IPA" written in black standard script is right justified beneath the edged portion of the weapon. A literal portion "Calavera" also in black stylized letters is centered at the bottom of the mark. The letter "C" in "Calavera" has a quartered inner design, the upper left quadrant contains the letter "B", the upper right and lower left quadrants each contain a letter "E" and the lower right quadrant contains the letter "R".
