Gee, talk about a mixed set of reviews!
A set of six Narex is 90 dollars on Amazon right now, and there is a set of 8 for 100.
Amazon also shows the current price of the 8 piece Stanley SW chisels for $160.
I fully understand the need to conserve dollars. I have been a fixed income retired person for two years now, and it sucks to have to be so cost focused (truly sucks - big time - and I do not recommend really retiring, ever). However, for an 8 piece chisel set, I would not quibble very much over $160 vs $100 if I really wanted the more expensive ones. And if I had to really control the budget carefully, I would get a 4-piece chisel set of whatever brand, and use it with enthusiasm and pleasure. Amazon shows a Narex set of four for $40 today, and I bet they are nice chisels to own and use.
On the other hand, the Narex chisels get great reviews on the internet and many good one here, too. I have Narex rasps that are fantastic for me, and haven't held or used the chisels.
Some Narex detractors here are really telling you they already have something else they like, or they don't like sharpening the Narex. Crap, I don't especially like sharpening anything, but alas, it is needed to pursue this hobby.
It turns out I have a set of Mifer chisels made is Spain that came in a nice wooden box (now with a warped lid), and the Stanley SW in the leather roll. I got the Mifer, 6-piece set about 25 years ago, and the S-SW set maybe 4 years back. And of course - they all need to be sharpened from time to time, and it isn't really any particular fun for me to do so.
And a final, tangential thought: I've have a cheap 1/2" Stanley from a big box store laying on my bench for years. It has a yellow, translucent plastic handle, and has been quickly sharpened many times using less than perfect techniques. Sometimes it gets thrown in t tool tote unprotected to go do a chore away form the shop. There are flecks of rust in many places despite me sanding them off a few times. When in the shop, I grab it often, and find it extremely useful and perfect for many quick trimming needed. My point is, hopefully, that I believe that almost any chisel can be used with great success if it is indeed sharpened, and if there has been a little practice in its use.
