1. A cutter adapted for use with a power tool comprising:
a housing assembly including an anvil;
a cog assembly including a drive shaft and a first and a second cog, a first intermediate cog, a second intermediate cog and a third intermediate cog, wherein the drive shaft is rotatably connected to the housing assembly, wherein the drive shaft has a first end configured to detachably connect with the power tool, wherein the first cog is disposed on the drive shaft and moves synchronously with the drive shaft, wherein the second cog is rotatably connected to the housing assembly and rotates upon rotation of the first cog, wherein the first and the second intermediate cogs are rotatably connected to the housing assembly in a manner that allows them to rotate synchronously about a same axis, wherein the first intermediate cog and the first cog are engaged with each other, wherein the second cog and the second intermediate cog are interlinked with each other by the third intermediate cog such that the second intermediate cog is not in contact with the second cog and the third intermediate cog is engaged between the second cog and the second intermediate cog, wherein the second cog, the second intermediate cog, and the third intermediate cog are configured to provide a mechanical advantage between the drive shaft and the second cog, and wherein the second intermediate cog and the first cog are arranged at opposite sides of the first intermediate cog; and
a blade connected to the cog assembly, wherein the blade is rotatably connected to the housing assembly and connected to the second cog in a manner that rotates synchronously with the second cog, wherein the blade has a cutting edge selectively cutting the object to be cut by the cutter, wherein the blade is rotatable between a deployment position and a cutting position with respect to the object, and wherein the cutting edge is disposed away from the anvil when the blade is in the deployment position, but is adjacent to the anvil when the blade is in the cutting position.
