First off, the zt 0804cf is one of my most favorite ZT's.
my only gripe with mine is that the lockbar goes all the way to the end of the scale. this doesnt happen with every one, but its a common issue that happened to a lot of folks as mentioned by alot of folks on the forum. it doesnt really make any difference in use.
While im disappointing they discontinued the 0804cf, its really their own fault.
ZT needs to implement CQi like spyderco does. but to be fair, its life cycle was rather short.
customers showed lots of feedback wanting things to be changed in order for them to purchase. alot of them said it was the blade, most didnt want a DLC coated blade or the blade shape.
it was also priced too high for most, so compromising was a good idea to sell to those folks. making the scale g10 or even just ti/ti would have helped reduce costs possibly and setting a different price bracket to sell to those who could afford it.
i bought mine under MAP pricing which is about the price they are going for now after they were discontinued. its worth it. i say if you dont like the DLC blade, have it removed/modified or get a regrind.
is the ZT 0850 its replacement? i have some issues with that, that i hope they address (see my videos on ig, if your interested) but ZT doesnt seem like they care about issues or changes that people want.
