Description

BACKGROUND OF THE DISCLOSURE

The present disclosure generally relates to apparatus for dermaplaning and, more particularly, to a dermaplaning tool that minimizes breakage of the head portion from the handle portion.

As shown in prior art FIGS. 1-3, the Applicant herein previously designed a dermaplaning exfoliation tool 10 to remove dead skin and peach fuzz with its single blade 50 to deliver a smooth complexion, even skin tone, and clear pore congestion. Dermaplaning enhances product penetration, helps makeup to go on smoother, and reduces the appearance of lines.

As shown, the tool 10 includes an aluminum handle 30 to optimize user control. The top end of the handle 30 includes a post 35 that is captured within the channel 46 between two halves 42a, 42b of the blade sheath or head 40, when installing the blade head 40 on to the post 35.

In practice, it has been determined that the two-piece head construction around the post 35 causes a weak point 40a (FIG. 2) at or near a seam 40b (FIG. 3), and that after extended use, or upon multiple on/off evolutions for blade replacement, the head 40 cracks at the bottom thereof.

As can be seen, there is a need for an improved head portion of a dermaplaning tool which minimizes breakage of the head portion.
