Professional pruning shears often have replaceable blades. There are three different blade designs for pruning shears: anvil, bypass and parrot-beak.

The electric shaver usually does not require the use of shaving cream, soap, or water. The razor may be powered by a small DC motor, which is either powered by batteries or mains electricity.
Harry's razor blades are manufactured at Feintechnik GmbH Eisfeld in Eisfeld, Germany. [9] Feintechnik was founded in 1920, [29] and was later nationalised in 1948 as VEB Feintechnik Eisfeld, [30] [31] which later privatized by German government agency Treuhand in 1990. [31] Feintechnik was acquired by Harry's in January 2014 for $100 million.

In 1939, a version of the vertical grass shears was invented having a long handle with a lever at the top, and wheels at the bottom with the shears. This enabled the user to trim the edge of the grass near the sidewalk and driveway. Powered trimmers have for all practical purposes replaced this type of grass shears. [1]
The lightness and rigidity of the blade compared to muscle and bone may allow blade runners to swing their legs faster than non-disabled runners. In comments on the article, Peter Weyand and biomechanist Matthew Bundle noted that the study found that Pistorius re-positioned his legs 15.7% faster than most world record sprinters, allowing for a ...
