You people need to get out more and pay attention to what the Canadianand Savage bolt disassembly tool looks like and what it can do.
These are modern reproductions of the 'Tool Removing Striker' as used with the SMLE and No4 & 5 Enfield Rifles. The tool is used primarily to adjust the length of the striker by screwing it in or out of the cocking piece, or to remove the striker from the bolt to allow the striker, cocking piece or striker spring to be replaced. To use the tool firstly the bolt head is unscrewed from the bolt, then the striker retaining screw is removed from the cocking piece. Once this has been done the tool (which is hollow) is placed over the tip of the striker and down into the bolt. The lugs on the end of the tool can then engage the collar of the striker and unscrew or tighten the striker as required. This reproduction tool has 2 features not found on the original tool. The ends of the 'T' handle are formed so that one end is a screwdriver for removing the striker retaining screw and the other is fashioned to fit the reverse screw head of the No4 rifle foresight retaining screw.
