How do you prevent corrosion ? |
|
|
The tang will need to penetrate the sapwood, which will be wet and have compounds in solution that may attack the metal. |
|
|
The blade isn't a problem as it can be left unfinished and subsequently ground to profile (and can be dipped in polymer anyway) but the tang needs to be exposed metal. |
|
|
And don't suggest stainless steel, please ... stainless blades don't keep an edge. |
|
|
Weld a carbon steel blank to a stainless tang. |
|
|
I'd be more concerned about the wood splitting as it dries, or otherwise being structurally less sound than a cut billet. |

//How do you prevent corrosion ?// - make a ceramic knife? |
|
|
This idea would work better with tools such as scythes, pickaxes and adzes where the haft passes through a hole in the blade; just hang the blade over a suitable branch and let it grow into a very tight fit. |
|
|
Don't trees produce callus around injuries? If so, it won't be
much good as part of a knife scale. |
|
|
A field of trees fruiting axeheads, surreal. |
|
|
Surreal, but not without precedent (of a sort). |
|
|
Also baked but not widely known to exist by the Arborsmith folks. [link] |

They say just lean any old shovel-head or un handled tool up against a sapling... and wait. |
