Hinderers have a
different feel, there's really no other way to put it. Whether it will be worth the extra cost to you can only be figured out one way: buy it and see if you like it.
To me, they are worth it. They are another level of precision and durability than ZT, even though from the standpoint of bang for your buck, ZT's are objectively offering more. Knife collecting is pretty inherently unobjective, I reckon.
I currently have 5 ZTs (0801 pimped, 0450 CF aftermarket, 0452CF, 0562 CF, 0909), and have owned two others (0350 BW, 0920). All seven are very good knives and you sure get a lot of bang for your buck with them priced below and above $200. They flip great, have excellent F&F, and use premium materials. All I have/had are well-designed by Rexford, Sinkevich, Hinderer, George, or Onion. I do like my current group and expect they're keepers, but when I go to my knife storage for any day's carry or go grab a few to play with or fondle, the ZTs rarely make it out of their drawer. It's hard to put my finger on exactly (flipper tab pun reference?), but there's something generic, maybe soulless, and un-exciting about them that keeps them out of my pocket and hand moreso than not only my RHKs, CRKs, Shiros and other mid-techs, but also my Sypdies and BMKs.
There's something about my Hinderers (XM18 3.5 Spanto, XM24 REK re-grind, MP1 Micarta, 2 G10 HalfTracks, and one XM3.5 Sparrow sold) that just appeals to me more. With one in hand, I just get a more palpable feel of craftsmanship. Mid-techs are definitely production knives too, but my RHKs have both a hand-made feel and a better feel in hand than my ZTs. There are subtle differences that speak toward a more individualized process of design and production that somehow appeal to me. There are definitely shortcomings too--RHK blades are thick and poor slicers; flipping action on my XMs is meh at best; the knives are heavy for their size and some are kinda pocket hogs; I had to do quite a bit of re-profiling to get my XM18 3.5 and MP1 edges to where I wanted them. Lots of guys that love Hinderers hate and change the Teflon washers, but mine are smooth as glass, more than quick enough for me with only one drop of liquid TriFlow added to each side, and seem in no way weak to me.
It really all just comes down to what appeals to you more. I also never look at these things as a question of value, as the knives cost what they cost and if you prefer one over the other then you have to pony up what it takes to buy one. I buy more knives on the Exchange than new from dealers and would suggest our OP do the same to try out a Hinderer. It's really the only way to tell--getting one in hand will let you know.
"Knife collecting is pretty inherently unobjective, I reckon." Right on, Halden.
