'I don't know. It is yellow, and smooth, and hard.'

'It is bone,' said his uncle, 'part of an ox-bone. But some handles are
made of wood.'

7. 'May I look at that knife near you, auntie? I mean the clean one.
Thank you!'

8. Then Dora wanted one to look at too; and they felt the edges softly
and found them very sharp. They looked at the blunt backs of the blades,
and then tried to read the maker's name.

9. 'There is no room to put the maker's name on a needle,' said Harry.
'But how do they get it on here?'

'It is stamped on when the blade is red-hot and rather soft.'

10. They could not make out how the handle was put on, so their aunt
went to the knife-box and got out an old knife that had lost its handle.
They saw that the blade had a long thin piece of iron at the end of it.

11. 'A long hole is made inside the handle, and this iron thing is put
into it, and made fast.'

So their uncle said, and then looked at the clock and saw that it was
time for him to go.
