Is that one genuine or one of the $750 ones from the USA?
"Well made reproduction of the extremely rare experimental bayonet (with tools in the handle). Made by 'cof' and tool set is marked 'ltf'. I purchased this piece as an original in the 1990's and it probably came out of Eastern Europe in the 1970-1980s. Overall in very good condition and will be a good collection fill-in until you can find an authentic SG42. It looks just like the original and much nicer than the cheaper recent reproductions."

If you want to criticise someone first walk a mile in their shoes. Then, when they come after you, you'll be a mile ahead and they'll be barefoot.
