HSS tip engaving burin / chisel

Hi here is a new kind of chisel (to be used with the hammer) for metal engraving :

The blade is of the same kind as for the hand tools, made out of a HSS jigsaw blade.

The tip is turned down to a diameter equal to the width of the blade. Then using the slitting saw on the lathe, I cut the slit for the blade, which is a little thinner than the slitting saw thickness.
Then I turn a steel sleeve to cover the blade. The blade is inserted after filling the slit with a bit of epoxy paste.

Here is the guide that I follow for the sharpening angles :
