A system and method for more efficient tracking and automatically recommend an optimizing pinhole locations on putting greens are disclosed. In one embodiment, a system and method may be directed to identifying a global position of a pinhole location using a turf analysis device having a global positioning system (GPS) module configured to collect and assimilate pinhole location data and condition data to a server database. The server may then determine an optimal location of a new pinhole location based on all previously collected pinhole location data and all previous condition data. By tracking and analyzing the pinhole locations for one or more greens as well as corresponding condition data, follow-on pinhole locations can be optimized. In some embodiments, measurements of turf conditions may be used to influence the optimization of determining pinhole location.

A golf utility apparatus includes a ball alignment tool having alignment marks on the upper surface with an arrow, and concave spherical sections at the corners, conforming to the curvature of a golf ball. To align a putt, a golfer places the golf utility device on the green behind a ball that has been circumscribed with an annular ring, removes the ball, calculates the line of play, and aligns the arrow therewith. The ball is then returned to the green with the annular ring aligned by the arrow on the alignment tool. A golfer subsequently aligns his putt using the alignment of the annular ring. The apparatus further comprises a ball marker, held in place by a magnet inserted through a bore hole in the alignment shaft. The magnet is thereby disposed beneath the surface of the upper baseplate to which the ball marker is secured when not in use.

A corrosion resistant retractable tool or opener device is provided. The retractable tool is integrated within an article of clothing. The integrated retractable tool includes a retractor having a housing that encloses an internal spring coil connected to a retractable cord for drawing the cord into the retractor. The cord is attachable to the retractable tool located at a first end of retractable tool. Retractable tool has a second aperture opposite the retractor end and a flange portion projects into the second aperture to provide a lever for urging a bottle cap from a top bead around a bottle. Retractor is fixedly attached, e.g., by stitching or adhesive means, within a sleeve portion integral with a seam, waistband, hemline or pocket of an article of clothing. The strap overlap sleeve portion encloses the retractable tool to conceal the retractable tool.

A cutting blade piece protective structure that prevents an obstacle from coming into direct contact with a blade portion of a cutting blade piece, saving light weight, saving a replacement cost at the time of breakage, and inhibiting lawn mowing performance by the cutting blade piece, is provided, and the lawn mower that includes the blade disk to be rotationally driven and at least one cutting blade piece attached to the outer peripheral portion of the blade disk, a blade guard for preventing an obstacle from coming into contact with the blade portion of the cutting blade piece is provided on the cutting blade piece. Preferably, the blade guard is attachable to and detachable from the cutting blade piece.
