At an other forum there has been discussion about the Narex (8105 model) chisels and consensus was that they’re good bang/buck.

I don’t know if they still practice it, but a shopkeeper here in Finland was in contact with Narex and found out that the initial bevel is achieved with a sandbelt machine. So the sharpest point has likely overheated and will not stay sharp long. The fix has been to sharpen them initially to lower angle (30deg?) which effectively removes the part that won’t stay sharp. He says that after his customers do this there was no more complaints.

I have only one other chisel (Sorsakoski 🙂 and don’t use that much so can’t tell anything else but that they seem to work well, especially when just sharpened. Their backs were mostly easily flattened too, only the widest (40mm) gave me any trouble.  I maybe should sand the backs edge a tiniest bit, it cuts skin when used for paring.
