Have they got a number on the side? Look like thread gauges or chasers.

One is numbered 7 and the other is 12 or L2 https://trademe.tmcdn.co.nz/photoserver/full/430877615.jpg

Rock chisels, removable handles, you use very similar for smoothing marble. But I wouldn't stake the farm on my memory.
Although they look a little thick for that.

Those are thread chasers, used to fit a wooden file handle on the tapered end. Haven't used one, or seen one in use since my aprenticeship

Now all you need to do is find out if they are for British Standard Whitworth or National Coarse.
