ABSTRACT:
A lathekin for use in stain glass window construction and the like has a handle with a blade attached to one end. The blade has a main convex edge which is doubly beveled. Spaced along the edge are two pairs of transverse projections. The transverse projections each have a tapered leading edge and a tapered trailing edge on either side of a peak. The peak extends from the edge of the blade inwardly to at least the depth of the channel of the came used in stained glass panel construction. The blade has a trailing edge which is also doubly beveled and which extends from a substantially normal intersection with the main blade edge to form a concave curve with the handle. On the opposite side of the handle is a concave upper edge which intersects with the main blade edge to form a point. A second blade is transversely mounted on the opposite end of the handle. It has a thin edge which extends transversely to the handle terminating in a substantially rectangular corner at one side and a smoothly radius corner at the opposite side. The handle and the blade are concavely curved along the edge joining the trailing edge of the first blade and of a length such that a portion of the handle and the second blade rests in the palm of the user's hand and the user's index finger tip rests on the upper edge of the blade when the hand is placed along the handle.
