About
This disposable Lancet use the sterile point to gently loosen the skin above and around the splinter, fold in half and use splinter pull out as forceps to grip the splinter and pull out. Surface skin has few nerve endings and can be gently picked away, exposing the splinter with minimal discomfort. Full instructions appear on the back of each card and individual wrapper.
Summary
This device was designed for the purposes of removing splinters. The device has three outstanding features: Firstly, sterile, which was made with the aim of achieving clean removals without wound infection. Secondly, Sharp Tri-bevel point, for loosening and pulling out splinters. Third, Kerf, which will allow the tool to folded for tri-bevel points to grip. We ask for your continued support and cooperation.

Engineering
After considering the normal usage of the design.
The ‘Weird’ loads it might be subject to are the following:
The ‘Weird’ loads it might be subject to are the following:
Fatigue
Fatigue is found in rings and base when being played with
Impact
Impact is found in the product when its dropped or banged against something
Tension
Tension is found in the rings when the user tries pulling it apart.
Flexure
Flexure is found in between the base and tip while force is applied on its side
Compression
Compression is found in the ring when stepped on or being bit.
Summary
The stresses that we considered to be the most problematic are the following:
Stress concentration:
Stress concentration is found when user is biting on ring. Also is found at base tip when leaning over on side or dropped.
Stress concentration:
Stress concentration is found when user is biting on ring. Also is found at base tip when leaning over on side or dropped.
Ergonomics
A study was conducted to determine device size, needs to fit the average male and female. Here is the data.
The minimal measurement from fingertip to apply 16 LB max force finger is .5, this would be the minimal dimensions that the device should close to.

Process
The feeding system pushes a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die. Each station performs one or more operations until a finished part is made. The final station is a cutoff operation, which separates the finished part from the carrying web.
