Having a name on a blade is one thing... Ray Mears for example, but he didn't make the knife... the makers name should always be on there..... if its handmade by a maker then his/her name should be on the blade, if its mass produced or not fully handmade, the companies name should be on the blade.
In general I agree, but there have been remarkable exceptions in the past.
Many goods sold by the Hudson Bay Company just had the HBC logo. Many goods sold by hardware store chains (long ago) just had their stamp. Norlund axes sold for a high price despite the fact that Norlund was a sporting goods company and their axes were all made by Mann Tool. The thing was that having the stamp of these companies meant something. They guaranteed that they sold only the best, and if you had bought something which didn't work, then they would make things good and cover the shipping which could be considerable in the Canadian North.
Now famous companies attach their logo to stuff made to the lowest production cost in third world countries. Marble's, Schrade, Cold Steel, etc., expecting that if people now see a famous logo then they focus on that and wouldn't know what a quality tool should be. Now I have a lot of blades made in far away places, from my CCK cleavers to my exotic stuff made by hand in primitive conditions, but they're stamped with something I trust. I value the stamp on my Moras because I've never seen a bad one so far. I even have some unstamped Moras which were sold as such by Lee Valley. They have shown all the attributes of the regular Mora which I'd expect as in the past I haven't expected anything but the truth off Lee Valley. Way back I got and wrote about a Normark stamped knife which I assumed at the time to be a re-branded Mora since it was identical to a Mora line. I got dragged over coals for that and rightfully so! You either know what a thing is or you don't.
So if I bought an expensive anything then I'd want to know that whoever made it or warranted it stood by it, and were proud to put their name on it. I wouldn't just look for a stamp or name, I'd want to know the value of that stamp or name.
