Thanks all for contributions, I will probably go for cheap type hacksaw blade and see how I get on. Just thinking as I type a couple of years back I made some lock picks from a hacksaw blade and I ground them and filed them rather easily, must have been cheap blades.

Does not have to be extremely hard for lockpicks,Go to some car parts place and you will find metal strips that come from window wiper blades lying on the ground outside, these are good for lockpicks.
