Old Sorby chisels question

Kerry in FortSask, Alberta

>Hi all,

I picked up a tray of chisels at a garage sale a couple of weeks ago for $10 which contained quite a variety - a few EA Berg socket chisels, a few Sorby's and some newer ones by Stanley and Fuller. The Sorby's all seem to have a black layer of something on them, not totally covering the whole blade, but nearly. Did Sorby sell their chisels painted or japanned or something, or is this just some kind of residue built up over the years. They appear to be quite old and given that the same old gentleman owned them all, I don't see why the Sorby's would be covered in residue and not any of the others which are just as old.

This is the 2nd garage sale this year that actually had some tools (and only the 3rd since I started woodworking 3 years ago). At these two sales this year I've managed to acquire this tray of tools, two Disston #8 saws and a saw set, a Rapier #700 plane and an eggbeater drill labelled Hoppe. Does anyone know who Hoppe was or is? I've been googling but can't seem to find anything relevant.

Cheers,

Kerry

>Here's a couple of pics of what I'm asking about re: the black coating. The first is one of the EA Berg's and the second one is a Sorby.

I guess what I'm wondering is if I want to put the Sorby's on ebay, should I be taking extra measures to get them nice and shiny.

>Looks like they might have been in a fire at some time. Before you put them on e-bay, you might want to check to see if they are still hardened.

>Hmmmm, that never crossed my mind. Some of them still have handles but I guess they may not be the original handles. How does one go about testing the hardness?

>I've got some gouges that have a black coating on all but the last 1/2", but it's more intentional looking than that. Are you sure it's not just dried anti-rust coating of some kind? I'd try polishing it off (SOS pad is good, or 220 sandpaper), and see how the steel looks under it.

Some carbon steels turn very dark with age, too, but they're usually shiny under the darkness.

>I have a small block plane made by Hoppe in West Germany. Unfortunately using american search engines only searches US sites so you cannot find Hoppe in Germany. If you go to www.google.de you will find a lot of sites called Hoppe manufacturing (including Hoppe-Volvo). Unfortunately I do not know enough German to find the wood working plane manufacturer.

The black coating on your chisels could be from a reducing environment rather than an oxidizing environment which would produce rust. I have seen a black coating on iron that has remained in very wet, even under water, environments for some time.
