J&R Dodge Juste Judicato - double shear steel carving knife

[kwackster]

A recent thrift shop find, and bought for a fart and three marbles (dutch expression, meaning for next to nothing)
From research i learned that J&R Dodge Sheffield didn't manufacture anything themselves, but instead bought high quality cutlery, razors and tools from well established Sheffield makers and resold these under their Juste Judicato (Choose Right) brand, for instance in two stores they owned in Amsterdam.
That is most likely how this carving knife ended up in the Netherlands.
Back in the day in this country J&R Dodge were known for the quality of the double-shear steel carving knives they offered for sale.

Interesting blade! How do you know it is shear steel?

[kwackster]

If you look closely at the blade surfaces (best to enlarge the picture to it's maximum) you can see that they are riddled with short black lines (actually voids), always running lengthwise along the blade.
That is a sign of the layered structure of this steel type.
Also: the surface of shear steel having a coarser structure can sometimes almost look like a layer cake, while the further refined double shear steel and it's still more refined cousin triple shear steel will have a finer layered structure.

The sequence in manufacturing seems to have been like this, where each metal type was made from the previous one: wrought iron > blister steel > shear steel > double shear steel > triple shear steel.
Carbon was added to wrought iron to produce blister steel, which in turn was made into shear steel.
Shear steel was already quite hard, and could be broken (or sheared) into pieces, which were then restacked, rewelded, and reforged into double shear steel, a more refined version.
Double shear steel itself could also be broken up, restacked, rewelded, and reforged into triple shear steel.

While none of the above were as refined as crucible cast steel, both shear steel and it's more refined versions double shear steel and triple shear steel were sought after for specific types of cutlery because of the toothy edges these steels would take, and which among others would work most excellent on all kinds of meat.
Where shear steel seems to have been known for it's very toothy edges, double shear steel edges were a bit finer toothy, while triple shear steel would have had the finest toothy edge.
Butchers in the old days highly prized these knives (in the Netherlands specifically the double shear steel ones), and specimens in good condition like this one are very difficult to find.

These 2 pictures taken in 1869 show the J&R Dodge display, which was made especially for an international exhibition in the Dutch Paleis voor Volksvlijt exhibition hall in Amsterdam in the Netherlands.

The knife really is a delight to work with and it gets used at least several times a week for cutting various types of meat, as well as softer breads and large apple pies.
It's kept sticky sharp freehand on a DMT red.

Part of the ingredients for an old school beef stew:





Probably the best apple crumble pie we ever had.

The brothers J&R Dodge owned two stores in the Netherlands in Amsterdam from 1820 up to 1884, where they sold high quality made in Sheffield knives as well as chisels and other cutting tools.
One store was situated in the Kalverstraat while the other used to be in the Leidschestraat, and both streets are filled with various shops to this very day.
