Chisel steel question

Matti Kuikka

>I cleaned an old chisel I found at our country place. It is +50 years old. It has a user made handle of curly birch and the blade is welded from two parts. The front/bevel part gets a better shine (it'll be a user). There's a sharp line across the blade about 8cm from the bevel showing different kind of steel. Theres also a visible etching of a crown and on the back is written "elektrost�l" (electric steel) so it's probably swedish. The steel feels hard when sharpening with watersones.

Question is what quality is the steel and what technically means elektrost�l?

>In 1855 the Bessemer process was invented. It created large quantities of steel for the first time in history. However, there was a lack of control of uniformity of the mixture of alloys. The gases involved also contaminated the mix.

There are several "eletric" processes, all of which are contrasted from the Bessemer process in that they do not blow air through the melt, but rather apply heat from an electric source.

This creates smaller batches of highest quality steel, and this is the reason your Swedes advertised the use of this steel in their chisels.

Various crucible methods actually pre-date the Bessemer method.
