Backout comb

Once I read about an amazing Far Eastern tree, Schmidt birchwhose hardness is many times greater than oak, approaching steel.
I wondered if it was possible to buy a piece of such a tree somewhere, just to hold it in my hands.
It turned out that it was impossible - alas, I did not find any mention of the sale of samples on the Internet. But I learned about lignum vitae, a more common analogue of birch woodSchmidt and one of the most durable types of wood in the world - it is four times harder than oak, twice harder than rosewood and one and a half times harder than ebony! In addition to hardness, the bacout is also interesting for its high oil content (thanks to them it is almost not afraid of water and does not rot, smells good and is relatively easy to process) and a beautiful wood pattern with fibers of adjacent annual rings located at a large angle.
And the main advantage of a back-out before Schmidt’s birchin the fact that combs are made of it that are easy to buy. On Aliexpress and ebay, different sellers sell dozens of options for back-out combs, which sellers call Green Sandalwood, a green sandalwood.
Combs start at 1-2 dollars, andend with 10-15, they differ in the frequency of the teeth, the number of parts (solid or glued in two parts - the second, by the way, also comes from the black horn), thickness (buyers of cheaper ones sometimes complain that the comb is not only thin, but also two combs from one batch vary in thickness) and the number of customer reviews. I took the rarest-toothed version for myself (my hair is tough and curly), picked up the shape of a pen that I liked and chose the most serious seller - to specifically buy a comb from a backout, and run into a fake, it would be insulting.
The hairbrush came in about three weeks later, it was packed unusually neatly - in a rigid cardboard box and blister made of thick polyethylene.
First impressions of the material are veryan unusual tree, it seems, is really a backout. The polish is almost perfect, the two wooden parts are well matched in color. The tree is incredibly hard, it does not push through with a fingernail and is hardly scratched with a knife, it slowly sinks in water, it emits a sonorous bone knock upon impact.
If you specifically try to look for flaws, thenyou can see that the teeth are not polished from the inside, and at the junction between the wooden parts in one place there is a ledge that can be felt with a finger if you specifically look.
Here's how the comb looked on the day of arrival:

Now, after a few weeks of use,the polishing is a little gone - now the comb on the texture does not look like a varnished radiol, but a carefully polished wood. But the fiber pattern (probably a bit clogged with dirt) has become much brighter and deeper - outwardly, this went to the benefit of a comb.
Here it is today:

As you already understood, the hairbrush more interested me not as a hygiene item, but as a sample of rare wood. But it turned out that as a comb, it is also very convenient.
Before that, I have used cheapplastic combs. When the hair grew longer than 10-15 centimeters, combing them became painful and long. I won’t lie that the new comb made combing my hair easy and enjoyable, but now I don’t have to grit my teeth every time I try to comb another curl - the hair glides on an oily tree better than on polyethylene with stamping marks. Perhaps I will consider this a pleasant bonus to a cute wooden toy made of rare wood, for which I initially took this comb, :-).
