Abstract: Novel combination squares for magnetically retaining a magnetic rule-type blade in a blade retaining slot. Novel combination squares including an L-shaped rule-type blade.

Abstract: The present invention is directed toward portable visible light beam pointing devices for set out, marking, and other handyman purposes, and thumb pressure mounted fixtures fashioned as hooks, hook racks, wall mounts, and the like. The pointing devices include a light beam generator, and a pair of orthogonal bubble vials for indicating the orientation of the pointing device along orthogonal axes in a horizontal plane. The thumb pressure mounted fixtures have a body member and at least one thumb tack-like member with a central portion having a steel spike transversely directed relative to the body member for driving into a supporting surface. The thumb tack-like members are intended to be manually collapsible from an arc shaped inoperative configuration with a concealed spike to a generally M-shaped operative configuration with an exposed spike for driving into a supporting surface.

Abstract: An extension set for a spirit level having an elongated leveling face for setting on a surface and defining a nominal working length, an opposite face to the leveling face, a pair of opposite major side surfaces, and a pair of opposite end sections, the extension set including a pair of discrete elongated U-shaped profile spirit level extenders for lengthwise accommodating an end section of the spirit level with its leveling face facing towards the surface and its opposite face facing away therefrom on spaced apart alignment on the surface such that the pair of spirit level extenders partially underlie the spirit level's leveling face and their remaining portions extend lengthwise therebeyond for extending its nominal working length, and a pair of spirit level clamps for mounting on the pair of spirit level extenders for clamping the spirit level thereon.

Abstract: A handheld seed planting device including a rule-like seed spacing member with two or more dibbers and a depth marker for facilitating seed planting in terms of the spacing between neighboring seeds and/or their seed planting depth. Dibbers preferably double up as depth markers but a depth marker may alternatively be implemented as a simple depth gauge for clipping onto a seed spacing member.

Abstract: A handheld layout and marking tool including a rule-like member and a sliding handgrip for sliding to a user desire position. The sliding handgrip preferably includes an integrally formed braking device rendering a one hand operable combined sliding handgrip and braking device. A handheld layout and marking tool having a headpiece and a detachable rule-like member for insertion into the headpiece lengthwise to interchangeably form either a framing square or a T-square.

Abstract: A spirit level comprising a body having a level face for setting a surface, at least one bubble vial mounted in the body, the bubble vial having a longitudinal axis generally perpendicular to the level face, and an optical transfer element fixed to the body which transfers an image of the bubble vial to a viewing plane generally parallel to the level face.

Abstract: Hand tool (1) including a pair of retainer clips (7A,7B) for securing a cylindrical level vial (6) in a suitable recess (3), and method of assembly therefor.
