Thank you David, we have discussed this earlier, but I was also interested in how they compare to the standard Premium line of Narex chisels, that is why I asked, if Richters are worth paying more. I would like to buy only 1/4, 3/8 and 1 chisels now (1/2 is out of stock) and I will buy others later if needed. At the same price point, there are also Pfeil, MHG, and Two Cherries chisels, I do not know if those brands are any better than Richters.
I do not want to buy a set, as I do not need both 3/4 and 1 chisel and maybe I would not need 5/8 or 1/2 chisel.
The key to telling if the premiums are any better than the standard line is the hardness spec. If they say they're 59 hardness, then they are almost certainly going to be austempered process instead of regular process. Austempering would make a good crow bar. You'd rather have standard process in a chisel.
I had the pfeil chisels, they were also good. I had only one experience with MHG mortise chisels eons ago and they weren't that great - they spec 61 hardness, there's no way the ones I had were that hard, but I haven't ever looked to see if anyone tested them with a lab quality hardness tester like a versitron.
Two cherries also behaved lower than their hardness spec (I had the hirsch labeled version) and later the WBW chisel test showed them to be well below 61. there's no guarantee that stuff doesn't change over time, but if you find chisels that roll on the edge and leave you feeling a burr when they feel dull, they're probably not 61 hardness.
if anyone says that there's little difference between a 58 hardness chisel and one at 62, they have no clue what they're talking about.
