To answer my own question a bit, in 1940's"
Stanley 51 $6.60/12
Stanley 52 $7.20/12
Stanley 64 $4.80/12, 24c/extra blade
Bailey 151 $10.20/12
Bailey 152 $10.20/12, 25c/extra blade
In the same catalog, Buck Bros Socket Butt Chisels are $11.11/12
Stanley 140 Block Planes are $3.05/ea
Putty knives are .50/ea
So are standard Stanley screwdrivers
Fancy Hurwood Ice picks are $6.60/12
So,no, they weren't preposterously overpriced....
In fact, they are rather cheap.....
Cheap enough to be sold by the dozen...
For about the price of a good ice pick....
