Manisha industries manufactures tigon plast-o-double plus soft blow hammer for dentless blows, heavy duty with steel handle and cushioned grip. The soft blow heavy duty hammer is soft for heavy impact, with non-chippable, blue detachable knobs fitted to coloured oval steel tubular handle with cushioned grip. An extended plastic stud enables full utilisation of the knob, as against a knob with steel stud insert where only 70 per cent of the surface is utilised. The blue knobs neither chip nor crack, even on sharp edges and corners, but simply wear out and are preferred by users. Also available are insert type copper and brass hammers, more durable than conventional cast sledge type and toughened plastic pink mallets for light blows.
