Blade steel is tin alloy(you know,the same stuff that is used to make the fake brass screws that are used in Tiwain import furnature and brake or strip like hard plastic) and if a laser was used to cut the hole it would melt the blade.Other than that is is worth the 75.00 buy it now price.Oh and lets not forget the fireing spring not being tempered and after every 10 opening you will have to bend it back in place.
Just wait till some poor sucker comes on here and says look what I just won on ebay,how rare is this one.
