-After our assembly of the product, the product worked the same as it did before we disassembled. The assembly process is the reverse of the disassembly process. The same tools were used to both disassemble and reassemble the product. An Analysis of our product could be done to figure out the power output of the saw. Another analysis that could be done would be to see how much stress the saw blade can undergo before breaking.

Another analysis that could be done would be to see how much stress the saw blade can undergo before breaking. According to Black & Decker the saw blade moves at 1850 strokes per min and has a stroke length of 13mm (1/2")and a voltage of 6V.

 The most disappointing aspect of the Black and Decker Handisaw is the charging apparatus. It may seem like a good idea to have a wall mounted charger but rather it forces the user to mount the charger someplace and always charge it from there. The wall-charger is a great option to have but it must also have the option of just plugging it into the wall. The wall charger is impractical if the Handisaw is brought to a worksite. The saw should be packaged with the wall-charger as well as a cord to plug into the wall. Also when it hangs on the wall-charger it can easily be knock off the charger and if it has the blade attached can be very hazardous. A small clamp or clip can be placed on the wall-charger to prevent accidental dropping.
