The resulting blade did have improved hardenability and the knife does hold a very good edge. This is not by any means intended to show the "correct" way to make a knife. The use of a high carbon spring steel or tool steel is always the better choice - however, it does suggest that some carbon may be added to the metal matrix for a case hardened effect if required. The portion of the video (2:35) showing the steel turning from carbon black to silver is certainly an interesting visual effect.

A number of viewers have asked something similar to:

"What happened at around 2:35? I don't understand why it flamed up like that."

The flame was quickly adjusted to become acetylene rich causing the flame to widen and deposit a layer of carbon on the surface of the blade. The interesting part is watching the black carbon deposit actually absorb into the metal matrix (the blade turns silver as the carbon soaks in). This is similar to a metal treatment process known as case hardening.

well, i have to say i love this video, and i plan on making my own some time ...hopefully soon. my question is, what is going on at the end with the wood in the liquid?

Included in the video is a short section on stabilizing wood handle materials. A knife scale is submerged in wood hardener under vacuum to enhance full saturation of the hardener. The air bubbles result from the vacuum removing air pockets from the burl walnut wood material.
