Shopmade 01 chisel set
Beitels.jpg
I am currently working on a set of 01 chisels for my own use. I like to make
my own tools, because then you are free to make them to your own specifications.
I’ve bought a few strips of 01 steel, and I shaped them with standard tools like
a bench grinder, angle grinder and a belt sander. It works out pretty good in
mine opinion.
I’ve made 12 chisels in total. 3 bench, 3 firmer, 2 paring and 4 butt
chisels. I have a connection with a proffesional heat treater with hightech heat
treatment equipment, so I have a good change on correct hardness and edge
holding after the heat treatment. I’m only a bit worried about how straight they
will be after hardening, but for now i’m very happy with the results.
Next step is to turn some nice handles, and to etch my personal logo on the
chisels. After that, I hwill have my own very unique chisel set, with no
matching pair in the world.

Nice chisels Wilco Flier.
I have made chisels from spring steel but not "O1." I would normally say that the heat treatment will not affect the straightness particularly as a chisel is reasonably robust in the first place as compared to say a knife blade where distortion is an issue.
With knives the trick is to quench the blade vertically and move the quenching medium around to keep cool liquid on the steel. I did this with my chisels too, although I suspect it wasn't neccessary. If you are taking your chisels to a specialist they should be aware of that potential if it indeed exists.
I think the handles make or break the final job so do find some really nice timber. Your chisels deserve it .

I don't know about higher quality, O1 is pretty standard tool steel that has been around for some time.
Double hardening is just that and it helps ensure that the whole piece has been hardened. Small variations in the way longer shaped objects are quenched, ie not rapidly quench or heated such that supports in a furnace doe not lead to even heating can lead to hardness irregularities in the final product. For a computer controlled furnace it is probably unnecessary but I find it is very useful where the heat source is marginal relative to the size of the object e.g. when a flame is used on a large or long object.
Yep same temp is used.
