When heat treating is off

One of my chisels is going blunt really quickly. On closer inspection, I saw that the edge was rolling which means the steel is not properly hardened. This is probably the result of inaccurate tempering. I'll have to harden and temper the chisel again. It's difficult to get a good picture of the rolled edge but here is my attempt.

Adam Garret

Adam Garret is a jeweller/engraver and uses engraving as a major part of the design. The scroll work and intricacy of his pieces are inspiring. He uses inlay, engraving as well as standard goldsmithing techniques to great effect.

Tom Herman

Searching for references to the type of work I have in mind, I found the website of  Tom Herman

Using a mixture of piercing and carving he makes intricate jewellery which seems to echo the use of borders and negative space found in decorative iron work. Although it's not explicit in his website, other articles about him have mentioned the making of tsuba as well as the use of chisels and tiny hammers so i can surmise he is using the same Japanese techniques I am interested in.

This is almost exactly the type of work I picture when I say carving and decorative iron work.
