One way is to cut olive at an 45 degree angle and cut with small hacksaw. The problem with this is that it may flare or damage the pipe, leading to replacement of the whole pipe. An easier way is to use a tool such as the olivepulloff tool (it costs about £20 and you can get one easily from Jee Dee Tools website). These do a good job, are quick and easy to use, and quite neat in removing olives off copper pipes. Further, even in space constraints, for example when removing olives off shower pipe's, a good olive puller will remove the olive off the copper pipe without leaving any damage to the pipe.

Sounds as though you have galvanised piping. Your only solution there is to take the section of piping out and inspect it at the next joint and see whether the condition of the piping is adequate. If not take out the next section of piping until you find that the piping is in better condition. My recommendation is to replace with copper, for two reasons, copper does not corrode and is easy to install. Would be advisable to replace the stopcock and even in some cases the tap as well.
