First impression of the Narex firmer chisels is good, the chisels have nice balance, the backs, of at least the 26mm, are very slightly concave. Less than 3 minutes on the 400 Atomic and it was flat. The bevel and back honed up quickly on the med India and Hard Black Ark developing a nice burr quickly and got a beautiful 'polish' on one of the hard JNAT's.
They may be keepers,
P.S. Ralph you shouldn't have but It looks like a keeper and thanks. I love tools, it is a sickness but there is nothing as satisfying as holding and using a old tool. The feel of the wood and the fit, how it can be perfect with nothing extra but everything needed to do it's job. The 'old ones' had much knowledge, it is a shame so much has been lost.
