Re: Upgrading chisels
William Duffield, on the Cohansey
>Your first problem with getting a really useful reply is finding an objective user who has and uses both a set of the L-Ns and the Japanese chisels you are interested in.
It took me a bit of "research" to find the particular chisels you are interested in on the JapanWoodworker website. When I found them, there were two significant disadvantages I immediately noticed vs. the L-Ns.
First, they have ferrous striking rings, with unforgiving, sharp edges. These will play havoc with your mallet. The hophornbeam handles on the L-Ns will dent, but not split and splinter, the striking surface of a competent wooden mallet. OTOH, a metal headed mallet, although it will not spit or splinter the L-N handles, is unnecessary. A hard, dense hardwood mallet drives them competently. I like the control and feedback I get with a hardwood mallet much better than a steel hammer.
Second, the geometry of the L-Ns, in particular the very low sides of the blades, makes them much more competent at trimming and paring dovetails. That's why bench chisels are supposed to be beveled on the back side, but only Lie-Nielsen seems to "get it." There are a few "special purpose" Japanese dovetail chisels that work correctly, but every one of the L-Ns works well, without modification, as shipped from the Toolworks, because the sides have been ground down to almost, but not quite, zero height.


Although FWW says these Japanese chisels are well balanced, I qaestion their analysis. The striking ring looks like it would make them top heavy, although not nearly as top heavy as the bluechips. I find the Lie-Nielsens to really be perfectly balanced.
If you are looking for a chisel that will hold the edge only a little longer than the bluechips, forget about the L-Ns. They far exceed your requirement :^J
If you plan to use them for paring, pushing them by hand, as opposed to striking them with a mallet, you will find the L-N handles much better designed and more comfortable for this purpose than either the bluechips or the Matsumuras.
