Special steels are necessary to make knives. To ensure the best cutting edge, stell high in Carbon is chosen.
Band of steel are cut into billets, carefully calculated to conform to the final specification of the knives. These are then heaten to 1150° centigrade to enable forging to take place. The red hot billets are carefully placed under the drop hammer in a 3-part mould which exactly corresponds to the size of knife in production.
Three blows of the massive drop hammer are needed, one in each section of the mould, to forge the billet into the required shape. Showers of sparks accompany this operation.
After forging, the knife is returned to the furnace and heated to 800° C to make it malleable once more, in order to trim the rough shape to the exact form required.
The tang is then pierced to take the rivets which will be used to maintain the handle on it.
