What yer saying depends on whether the tools are HSS. Personally I've not
seen any Sorby M2 HSS gouges or chisels. So I'm assuming the original
poster is talking about A2 turning tools which are not HSS. If you blue a
A2 tool steel turning tool you will soften the edge. So what are the
tools
being used?

I have both non-HSS and HSS steel tools. When I purchased my lathe, I also
bought a non-HSS beginner set of tools. My plan was to buy the beginner set
of tools and then over time buy better tools to replace the cheapies. I
have recently just purchased a Sorby HSS 3/8" bowl gouge and Sorby HSS 3/4"
roughing gouge.
