HSS is so hard that it is difficult to grind, but you can grind it with a diamond whetstone.
You can keep the sharpness even in hard work.
It requires skill, but it can be sharpened like White steel.
I will list the review of the buyer who used it.
”I finally had some time to sharpen the HSS chisel
It sharp easy on my diamond stones and it got very sharp.
I then tested it on some American white oak and some Baltic Birch plywood which has many layers. It held up for about 50 hard hammer hits before the edge deformed & dulled. I was happy with the performance as those are 2 very hard materials and the plywood has glue and who knows what else in it.”
