The golf tee herein comprises a head; a stem; a ground-gripping ring or rings; and a wide and sturdy pointy contoured tip section. ## Claims ### Claim 1 A golf tee, comprising: a head comprising a central pillar, a collapsible continuous wall surrounding the pillar and having a rim, such that a hollowed out portion is present between the wall and the pillar, wherein the central pillar comprises a planar or contoured top surface, a top end, and a bottom end; wherein the wall is circular in a horizontal section, and of a symmetrical, curved or straight bowl shape; wherein the top surface of the central pillar is lower than the rim, such that the rim is a top edge of the wall configured to securely receive a golf ball while allowing the golf ball to rest on the central pillar; a body operatively connecting to the head and located below the head, and the body comprises: a stem below the head, a gripping ring structure below the stem, and a terminal grounding tool below the gripping ring structure, wherein the gripping structure is configured to be at least partially buried in a ground in which the golf tee is lowered and to grip the ground; wherein the terminal grounding tool culminates in a pointy tip; wherein the golf tee extends along a central axis, has a height extending from a top of the head to the pointy tip along the central axis, and has a center of mass of the golf tee located at a distance of 40% to 60% of the height from the pointy tip along the central axis. ### Claim 2 (depends on 1) The golf tee of claim 1, wherein the stem maintains a diameter from a top direction to a bottom direction or increases in diameter from a top direction to a bottom direction. ### Claim 3 (depends on 1) The golf tee of claim 1, wherein the gripping ring structure comprises a plurality of gripping rings and the pointy tip is incorporated below the plurality of gripping rings. ### Claim 4 (depends on 1) The golf tee of claim 1, wherein: the gripping ring structure comprises a plurality of gripping rings or a singular gripping ring, and the grounding tool is bullet-shaped and comprises a top ledge created by a symmetrical expansion from the body, such that a top of the bullet shape has a diameter of less than or equal to an outer diameter of the singular gripping ring or the plurality of gripping rings. ### Claim 5 (depends on 1) The golf tee of claim 1, wherein the gripping ring structure comprises a plurality of gripping rings or a singular gripping ring, and the single gripping ring or the plurality of gripping rings is configured to resemble an inverted L-shape on cross section. ### Claim 6 (depends on 1) The golf tee of claim 1, wherein the gripping ring structure comprises a plurality of gripping rings or a singular gripping ring, and the single ring or the plurality of gripping rings is configured to resemble a rhomboid or trapezoid shape. ### Claim 7 (depends on 1) The golf tee of claim 1, wherein the gripping ring structure comprises no more than a single bulb shaped expansion from the body below the stem. ### Claim 8 (depends on 1) The golf tee of claim 1, wherein the grounding tool is a bullet-shaped feature and has a ledge with a sharp or curved edge at top of the grounding tool. ### Claim 9 (depends on 1) The golf tee of claim 1, wherein the gripping ring structure comprises a plurality of gripping rings created by ‘L’-shaped or ‘C’-shaped grooves in the body below the stem. ### Claim 10 (depends on 1) The golf tee of claim 1, wherein the gripping ring structure comprises a plurality of gripping rings, and the stem is as wide as an outer diameter of the plurality of gripping rings, wherein the plurality of gripping rings are created by concentric grooves placed on the body below the stem. ### Claim 11 (depends on 1) The golf tee in claim 1, wherein the central pillar is configured to carry a weight of the golf ball axially. ### Claim 12 (depends on 1) The golf tee in claim 1, wherein the terminal grounding tool comprises a non-expanded continuation of the stem, wherein the non-expanded continuation of the stem ends in formation of the pointy tip. ### Claim 13 (depends on 1) The golf tee of claim 1, wherein the gripping structure comprises a single gripping ring or a plurality of gripping rings, or a plurality of gripping grooves, wherein the single gripping ring, the plurality of gripping rings, and the plurality of gripping grooves are disposed concentrically on a lower section of the body below the stem. ### Claim 14 (depends on 1) The golfing tee of claim 1, wherein the terminal grounding tool is bullet or torpedo-shaped. ### Claim 15 (depends on 1) The golfing tee of claim 1, wherein the head comprises between 15% and 25% of a mass of the tee. ### Claim 16 (depends on 1) The golf tee of claim 1, wherein the head forms between 10% and 20% of the length of the tee. ### Claim 17 (depends on 1) The golf tee of claim 1, further comprising a downwardly sloping skirt surrounding at least part of the stem, the skirt having a top circumference joined to the stem and a bottom circumference larger than the top circumference, the bottom circumference being vertically aligned with a junction between the stem and the gripping ring structure or is located above the junction, wherein below the top circumference a hollow space is formed between the skirt and the stem. ### Claim 18 (depends on 17) The golf tee of claim 17, wherein an angle between the central axis and an inclined surface of the skirt connecting the top circumference and the bottom circumference is between 75 and 80 degrees. ### Claim 19 (depends on 1) The golf tee of claim 1 comprising a flat skirt radially extending from the stem, wherein a bottom flat base of the skirt is vertically aligned with a junction between the stem and the gripping ring structure or is located above the junction. ### Claim 20 (depends on 1) The golf tee of claim 1, wherein the gripping ring structure and the terminal grounding tool together form about 35-50% of a mass of the golf tee.
