Handle compositions, methods of use and methods of making

1. A handle comprising:

one or more surfaces suitable for contacting one or more digits of a user, wherein the handle is radially asymmetric,

wherein the one or more surfaces comprise a first surface suitable for contacting a first digit of the user and a second surface suitable for contacting a second digit of the user;

wherein at least one of the one or more surfaces comprises a concave feature,

wherein the second surface is separated from the first surface by a ridge,

wherein a volume of the handle is substantially the same as a volume of space created by the user's curved digits and a portion of the user's palm when his or her hand is relaxed, and

wherein the portion of the user's palm comprises less than 50% of the user's palm and the portion of the user's palm is a portion above an imaginary line extending from the user's thumb to the user's pinky finger when the user's thumb is positioned above the user's pinky finger.

2. The handle of claim 1 , wherein the one or more surfaces further comprise a third surface suitable for contacting a third digit of the user.

3. The handle of claim 2 , wherein the one or more surfaces further comprise a fourth surface suitable for contacting a fourth digit of the user.

4. The handle of claim 3 , wherein the fourth surface is adjacent to the third surface.

5. The handle of claim 3 , further comprising:

a cavity adjacent to the second surface, third surface, and fourth surface.

6. The handle of claim 5 , wherein the cavity is separated from the first surface by the ridge.

8. The handle of claim 2 , further comprising:

a lower surface adjacent to the ridge, the second surface, and the third surface.

9. A method of manufacturing the handle of claim 1 , comprising using a high-throughput manufacturing method.

10. The method of claim 9 , wherein the high-throughput method comprises 3D printing, 4D printing, stamping, blow molding, and/or injection molding.

11. A handle comprising:

a) a first surface suitable for contacting a first digit of a user;

b) a second surface suitable for contacting a second digit of the user, wherein the second surface is separated from the first surface by a ridge;

c) a third surface suitable for contacting a third digit of the user, wherein the third surface is adjacent to the second surface;

d) a fourth surface suitable for contacting a fourth digit of the user, wherein the fourth surface is adjacent to the third surface;

e) a cavity adjacent to the second surface, third surface, and fourth surface, wherein the cavity is separated from the first surface by the ridge; and

f) a lower surface adjacent to the ridge, the second surface, and the third surface;

wherein the handle is radially asymmetric;

wherein at least one of the first surface, second surface, third surface, or fourth surface comprises a concave feature;

wherein a volume of the handle is substantially the same as a volume of a space created by the user's curved digits and a portion of the user's palm when his or her hand is relaxed, and

wherein the portion of the user's palm comprises less than 50% of the user's palm and the portion of the user's palm is a portion above an imaginary line extending from the user's thumb to the user's pinky finger when the user's thumb is positioned above the user's pinky finger.

12. A method of manufacturing the handle of claim 11 , comprising using a high-throughput manufacturing method.

13. The method of claim 12 , wherein the high-throughput method comprises 3D printing, 4D printing, stamping, blow molding, and/or injection molding.

14. A handle 100 comprising:

a) a first surface 101 suitable for contacting a first digit of a user;

b) a second surface 108 suitable for contacting a second digit of the user, wherein the second surface 108 is separated from the first surface 101 by a ridge 102 ;

c) a third surface 109 suitable for contacting a third digit of the user, wherein the third surface 109 is adjacent to the second surface 108 ;

d) a fourth surface 110 suitable for contacting a fourth digit, wherein the fourth surface 110 is adjacent to the third surface 109 ;

e) a cavity 104 adjacent to the first surface 101 , second surface 108 , third surface 109 , and fourth surface 110 , wherein the cavity 104 is separated from the first surface 101 by the ridge 102 ;

f) a lower surface 103 adjacent to the ridge 102 , the second surface 108 , and the third surface 109 ; and

g) an attachment point 106 on or within the ridge 102 , wherein a wand 105 is attached to the handle at the attachment point 106 ;

wherein the handle 100 is radially asymmetric;

wherein at least one of the first surface 101 , second surface 108 , third surface 109 , fourth surface 110 , lower surface 103 , and cavity 104 comprises a concave feature; and

wherein the volume of the handle 100 is substantially the same as a volume of a space between a user's palm and digits when his or her hand is relaxed.
