Below are some Berg chisels with seldom-seen or unusual blade markings.
The middle chisel in the photo below has what I call a “Flying D” on it. It was stamped only on the middle chisel — one of a set of five. I have no idea what it signifies, but I have seen it on a few other chisel blades.
Here is the same mark stamped on an Eskilstunasteel “Esteel” chisel. I’m starting to think that it looks like a flying saucer. 🙂
The Berg chisel below has a Crown symbol and an “S.J.” imprinted on the back of its blade beside the typical Berg text and shark. I see this mark every so often on Swedish tools. I have read that this mark has something to do with the Swedish Government, or the Swedish Military, or the Swedish Train System. I hope to be able to track down the correct information eventually.
The chisel below has a crossed razor and pliers imprinted on the front of the blade. This is the only Berg tool that I’ve seen with this imprint so far.
This is an earlier Berg chisel. The handle does not look original, although it may have been modified at some point.
Here is the razor and pliers imprint on the front of the chisel.
Here is a closer look.
The Berg shark is an earlier variation, indicating that this is an older Berg chisel.
