When it is time to fix furniture and a heavy hammer raised, aiming for that tiny nail and hammer could be a scary moment, because the hammer may land on the fingers instead. This is even a bigger problem for those elders who need reading glasses or those girls who do not have the muscles a slight mistake and Whack! Screams! Putting the nails in with 45-degree angle for holding is also a problem, because with a slip of hand and the wall surface is damaged.Detached the end of the handle of the hammer, place the nail in, fix it on the wall, Whack, and the nail is in place. Never again will you be sucking a smashed finger!
