Topic tags/keywords: mystery chisel

I refurbished a vintage chisel for my brother-in-law for Christmas. It’s a Witte Hardware 1XL paring chisel 1.25” wide. When I polished it, I noticed a change in the metal about half-way down the blade. The line is on both sides of the blade. It looks like the blade is two pieces of metal welded together. I know that some cutting tools are made of softer metal with a harder piece wielded in for the cutting edge. I speculate that’s what’s going on here. But it could be something else.

So the question is should give this to my brother-in-law or keep it for myself?

More specifically:
How was the chisel made?
Is this an extremely rare and highly-prized collector’s chisel?
Or is it a run-of-the-mill every-day working tool?

My guess on the line is that is where any oil quench or other cooling technique was ended (the line marks how far they dipped it into the fluid vat).

I’m sure some of the smithing folks here can give a definitive answer.

Yes, probably the limit of the hardening of the steel.

You did a nice job refurbing that chisel, looks great. The line is certainly nothing I’d worry about. Witte is (was) a national hardware distributor, meaning the chisel was made for them as a rebrand. Who made it? Someone (not me) knows and might post more info. As far as keep vs. gift, I guess that depends on what you want to do and how much you like you BIL.

Thanks. It wasn’t something I was worried about . . . it was an old rusty chisel with no handle when I started working on it. Mostly a learning experience. Quench line makes lots of sense.

I gave it to my BIL and was always going to give it to him for a umber of reasons. I cleaned it up and polished it but he helped me sharpen it with his Tormek and Shapton Water Stones. I only asked that question so I could show it to him . . . He thought it was almost as funny as I did . . . almost.

Used to be, that line was where the tool steel was welded to the iron body of the blade….a Laminated chisel. Might even see another such line in the bevel’s edge.

If the line extends all the way around the blade, then it could be caused by the quenching process. If only on one surface???

It’s on both sides. It’s a little hard to see but the last two photos show the line on each side. It’s roughly straight across on the “top” and a little bit crooked on the “bottom” side of the blade.
