That Gränsfors froe is obviously electrically welded. With correct preheating and correct rods and slow cooling one can usually weld spring steel and tool steel electrically with good result.
Fire welding spring steel to spring steel is very difficult. Old time blacksmiths and to a lesser degree traditional blacksmiths of today generally build the tool body from wrought iron (nowadays from mild steel) and then fire weld the edge steel in place. That way one can use the surrounding wrought iron to protect the steel against overheating in the forge. Steel is very easily overheated and then it catches fire and the carbon burns out of it. An old time froe was likely made from a flat bar of wrought iron folded to form the eye and with a strip if steel sandwiched in to make an edge. Such a froe would be unaffordable with today's wages.
Punching the eye in a froe would likely not work. There isn't enough of a poll and the billet would likely split. With modern steels it might just barely be possible but with old time materials it was utterly impossible because before they started to roll profiles directly from molted steel coming out of the converter there was a more pronounced grain structure in the rolled material. I would think it necsessary to hire a very expensive lawyer to avoid any liability issues if making froes with punched eyes.
For this sort of kindling splitting there is no seansible alternative to a hatchet or small axe. All other alternatives are significantly less effective and most alternatives are more expensive.
