Japanese chisels - ferrule question

Hey all,
The inside of Japanese chisel ferrules are beveled. Does the wider end go on up or down on the handle top end? Miñe handles are nicely mushroomed, id have to saw the mushroom off to get the ferrule off to inspect it and i don't want to do that.
Any advice appreciated, thanks

Hope these are clear and understandable.
Was given this with a Japanese plane making class.
Wider part at top to act as wedge to hold on hoop.
Small taper on bottom for smooth entry.
Shave, file, compress with hammer till nice fit.
Place hoop.
Mushroom.

that reminds me, I have to set the hoop on my chisels one day.

Have a look at these mate

Wide end towards the blade. This prevents the hoop digging into the handle and causing splitting.

Thank you all.
