I have a HELLE "Jaktniv" which is more than 30 y/o and served me very well under very harsh and demanding conditions. Took it out from the place I put it for a peaceful retirement, cleaned it, repolished a bit, resharpened a bit and the good old knife looks as good as new.
I don't know which Mora or Helle models you mean, but this one is rather pricey (mine is SOOO old,a model stilll with the aluminium guards, which these days are made of brass, but the blade is already of the sandwich type).
Quality knives, no doubt.
