Week 9 Blog

   For this week's blog i decided to talk about the design of a razor blade.  In particular i will talk about the Gillette Mach3 razor.  The design of the razor is very similar to other razors.  It has a simple straight handle that the user can hold onto while using the razor.  The handle has some rubbery grips on the side which makes it easier to hold when wet which is very useful for razors since they're always used in wet conditions.  The next key part of the handle's design is at the top where different blades can snap onto.  This allows different types of razors to be used on top of the handle which can allow different types of users to use the same handle.  Razor heads can be easier popped off by pressing the button on the handle which makes replacing blades very easy.
   The actual razor head is very important for the process and has a nice design to it as well.  The razor head first has a blue strip of rubber that hits your face before the blade does.  This helps raise hairs and remove excess dirt before the blades get there.  Then there are 3 blades that actually cut the hair.  These blades are sharp at the time that you purchase them.  Overtime these blades dull down fairly quickly which gets to be annoying.  this is where the third strip on the razor head comes into play.  There is a green aloe strip(depending on razor head model) above the blades which releases aloes ans skin soothers onto your skin after the razors have passed.  This strip also deteriorates in color as the blade gets used and serves as a nice indicator of when razor heads should be replaced.  This was a nice way of combating the problem of short lasting razors.
