I generally use modern Irwin Marples chisels. I like the heft and bomb proof handles. However, most of my work prior to a couple years ago was large pieces. Finer work needs finer detail; in this spirit I picked up a couple of Narex chisels from Lee Valley. Shortly thereafter I picked up several Lie-Nielsen chisels. Around that time I pilloried the Narex chisels on Chris Schwarz's blog.
I am here now to officially recant! I did have to put the Narex chisels through a fair amount of prep work to make them useful whereas the Lie-Nielsen simply required a secondary bevel. I have used the Narex and Lie-Nielsen equally quite a lot since my original criticism and they both have performed flawlessly. I actually prefer the small Narex for cleaning tough to reach areas, but have found their metric base a tad inconvenient. I will buy more Narex chisels as the need arises.
