In my machining career I have only purchased measuring tools that are Starrett, Mitutoyo, or Brown and Sharpe. But I found a used depth mic at a rummage sale and it has proven to work well. It is NSK brand, made in Japan. It has a good feel and it holds calibration. What has been your experience with this brand and is this make still on the market? Is it worth buying other NSK stuff?
Mitutoyo has never NOT had "local" competion in Japan. NSK, Peacock, etc. Decent stuff, second-tier ..or maybe not so much?
Names get "re-used" and co-opted. Here's an example of a website that just doesn't reflect older and wider history in related industrial products. One would have to spread a wider net, dig history, find the "real" NSK, and then track the keidanren they are part of [1]:

Or just go by what evidence is in your hand?
I just like Mitutoyo BETTER. Superb finish. And perhaps because I've never once had to WORRY about them - could just get on with USING anything as had their name on it?
Not as big a deal as all that.
I've avoided Starrett as over-hyped for easily 60 years but have "some" Starrett goods in with B&S, P&W, Scherr, Hamilton, Dorsey, Dearborn Gage, Cadillac Gage, Herman, DoAll, Weber...Mauser, Mahr, Polish and French - even East German and Russian goods..
..and also some right-decent Chinese-made manual mics as are good enough to be users AND "keepers".
Otherwise? "Kleenex class" disposable Chinese DTI's and more than one "grade" of calipers, some of which I'd shed no tears at all over if crushed, dropped, or gone coolant-soggy.
Whatever WORKS good IS good..
Having "grades" cheap enough to risk a bit of rough and tumble whilst the "good stuff" is held for more demanding work done slowly makes a bit of practical sense.
JF use 'em. Even use 'em UP. They be TOOLS, not sainted monuments, the lot of 'em.
