These look very different than those. I also found some blogs indicating that newer Hubertus knives are not as good in quality as they used to be (the company has a long tradition, since 1899, and are still family-owned). I found sites that sell knock-offs, definitely Chinese (not sure how they get away with this), and even read blogs that indicated new manufacturing was occurring in China.
I have no idea what of this is true or not true... But I trust my brother's judgement in having these in his collection, and also that of the experienced knife-maker who looked at these for me (he also cleaned and oiled them). This listing is for for all 4 knives, described as follows. (2) Hubertus "The Guardian" rostfrei swinguard, leverlock; black buffalo horn handles; spear point 7 - EX; w/ boxes.
