There were some of these shorties (thread 23) doing the rounds in the UK a few years ago. I think made from the short Indian No1 bayonets without the groove in the blade. Easy to tell...., like this one.
Maybe a better method of straightening a bent blade (see thread 21) is to put the blade on a suitably clamped vice and put a piece of pipe over the bent part of the blade and GENTLY straighten by levering pipe. There's more control this way to because by definition, a bend takes place over a length and you can clamp, bend, clamp, bend to suit. FAR better to treat tempered steel like this than whacking it I say
