- Do you like Chinese cleavers?
-
Why yes, this *is* the cleaver thread isn't it?
- Touche. But what of the handles? Do you admire their stark functionality?
-
I do!
- But despair of their plain and ugly looks?
-
Yes, that's me!!
- And don't want to faff around trying to make your own?
-
NO. HARD WORK. BOOO!!!
- Well then, buckle in. For I am here to help...
I've made quite a few handles for Cai dao before; it isn't desperately difficult to knock the old one off, snap a bit of the tang off, and make a new handle in whatever shape or style you want. Here's a nice one on a 1302:

But not everybody will have the kit or inclination to do that. And I only do it on slicing cleavers, as bone cleavers might exert too much shock force on a hidden tang handle like that. So things like my Kau kong still have their boring light wood handles, in the picture below I've given it a quick coarse sanding:

What I'm about to do that isn't new or revolutionary in any way - people do it to wood all the time, including I'm sure many people here. But this is the first time I've tried it, and I think it's worked quite well for very little effort. I'm going to 'ebonize' it; which is a reaction between iron acetate and tannin, turning it darker, you can actually make it almost black depending on the type of wood and its tannin content.
To make iron acetate we're going to use these things which everybody has a packet of under the sink, but never uses because they're nasty and little bits of metal get everywhere:

I kinda pulled a couple apart to get rid of the pink soap bit, which probably wouldn't help, and then cover in white vinegar, leave for a few days or a week, and chemistry happens. You can speed chemistry up by heating stuff - if you simmered them together it'd probably only take a couple of hours, but the smell of boiling vinegar isn't very nice:

Then you just brush it on your wood really, but there are a number of ways you can increase the effect beforehand if you want. Tannins are in a lot of natural products; leaves, wood, and the skins of fruit in particular, it's the stuff that makes your mouth go dry when drinking heavy red wine, or strong tea. So if we do something like this:

Then we can soak some of the tea tannins into the handle first, before applying the vinegar x steel wool iron acetate solution. Bit of banana skin or walnut shell in that cup of tea would probably ramp it up further. Red wine would work too, and doesn't make the handle red.
Anyhow, at the end of it... nothing happened. So I concluded I'd done something wrong, threw away my vinegar and steel wool mixture (stupidly), and went off to watch the rugby. Coming back to it at half time though - it had actually worked, and I think quite well. It certainly looks better than before, and the fact that a chinese cleaver handle is round means that the grain on the wood gives you kinda cool wavy-circular patterns too:

So that's how to ebonize stuff. And I'm sure if anyone else tries they'll probably get far better results than my first effort here. But I quite like it, and will be doing again soon I think.
