A blade for a demolition shear, said blade comprising:

• a first longitudinal side wall (402, 1702, 2002, 2102, 2502, 3002, 3202);
• a second longitudinal side wall (403, 1703, 2003, 2103, 2503, 3003, 3203) spaced apart from said first longitudinal side wall;
• a first end wall (404, 1704, 2004, 2104, 2504, 3004, 3204) extending between a first end of said first longitudinal side wall and a first end of said second longitudinal side wall;
• a second end wall (405, 1705, 2005, 2105, 2505, 3005, 3205) extending between the second end of said first longitudinal side wall and a second end of said second longitudinal side wall;
• and
• a front wall (406, 1706, 2006, 2106, 2506, 3006, 3206) which extends between said first and second end walls and between said first and second longitudinal side walls;
• said first and second longitudinal side walls, said first and second end walls, and said front wall forming at least one cavity there between;
• an intersection between said first end wall (404, 1704, 2004, 2104, 2504, 3004, 3204) and said front wall (406, 1706, 2006, 2106, 2506, 3006, 3206) defining a first piercing tip (413, 1714, 2017, 2113, 2513, 3018, 3214);
• and
• an intersection between said second end wall (405, 1705, 2005, 2105, 2505, 3005, 3205) and said front wall (406, 1706, 2005, 2506, 3006, 3206) defining a second piercing tip (414, 1715, 2018, 2114, 2514, 3019, 3215);
• said first and second longitudinal side walls said first and second end walls and said front wall being formed as a single body;
• and
• characterised in that each of said first and second end walls comprises a corresponding respective protrusion which faces inwardly into said at least one cavity (602, 602′, 1801, 1801′, 2130, 2130′, 2701, 2701′, 3101, 3101′, 3223, 3223′);
• said blade for a demolition shear being indexable between a first position and a second position;
• wherein, in said first position, the first piercing tip is presented for piercing use and in the second position the second piercing tip is presented for piercing use.
