There were many early manufacturers of chisels RHD45. The nomenclature depends on where you stem your training from. And where your teacher stemmed their's from. Shipwright, sashmaker, carpenter, lutier?.
Before I placed an order somewhere, I would go to a flea market and buy a bucket of junk chisles. I would learn to shape and sharpen them, and then visit a Woodcraft, or other woodworking store on a saturday morning and meet the chisel devotees.
It is the same amount of work to transform a $1000.00 blank into sawdust as it is a $25.00 piece of walnut. YMMV
I had a five year apprenticeship with the patternmaker/modellmakers dept and the first year was spent learning to sharpen and care for the chisels and plane irons correctly. The main point that was stressed to me was to ensure the flat side opposite to the bevel edge was absolutly made flat by wiping the blade on an oilstone-later diamond stones in a figure of eight movement until all the front area where the edge is to be is flat. Otherwise an edge cannot be achieved.
This stays with you for life.
